What is (are) Hepatitis B: What Asian and Pacific Islander Americans Need to Know ? | Hepatitis B is a liver disease spread through contact with blood, semen, or other body fluids from a person infected with the hepatitis B virus. The disease is most commonly spread from an infected mother to her infant at birth. Hepatitis B is also spread through sex, wound-to-wound contact, and contact with items that may have blood on them, such as shaving razors, toothbrushes, syringes, and tattoo and body piercing needles.
Hepatitis B is not spread through casual contact such as shaking hands or hugging; nor is it spread by sharing food or beverages, by sneezing and coughing, or through breastfeeding. |
What is (are) Hepatitis B: What Asian and Pacific Islander Americans Need to Know ? | Hepatitis B may start as a brief, flu-like illness. Most healthy adults and children older than 5 completely recover after the bodys immune system gets rid of the virus.
Hepatitis B becomes chronic when the bodys immune system cant get rid of the virus. Over time, having the virus can lead to inflammation of the liver; scar tissue in the liver, called cirrhosis; or liver cancer. Inflammation is the painful red swelling that results when tissues of the body become infected. Young children and people with weakened immune systems are especially at risk. People who were infected as infants have a 90 percent chance of developing chronic hepatitis B.1 |
Who is at risk for Hepatitis B: What Asian and Pacific Islander Americans Need to Know? ? | Since 1986, a hepatitis B vaccine has been available and should be given to newborns and children in the United States. The vaccine, however, is unavailableor has only recently become availablein many parts of the world. You are at higher risk for hepatitis B if you or your mother was born in a region of the world where hepatitis B is common, meaning 2 percent or more of the population is chronically infected with the hepatitis B virus.1 In most Asian and Pacific Island nations, 8 to 16 percent of the population is chronically infected.2 |
What are the symptoms of Hepatitis B: What Asian and Pacific Islander Americans Need to Know ? | Hepatitis B is called a silent killer because many people have no symptoms, so the disease often progresses unnoticed for years. Unfortunately, many people first learn they have chronic hepatitis B when they develop symptoms of severe liver damage, which include
- yellowish eyes and skin, called jaundice - a swollen stomach or ankles - tiredness - nausea - weakness - loss of appetite - weight loss - spiderlike blood vessels, called spider angiomas, that develop on the skin |
Who is at risk for Hepatitis B: What Asian and Pacific Islander Americans Need to Know? ? | Anyone can get hepatitis B, but some people are at higher risk, including
- people who were born to a mother with hepatitis B - people who have close household contact with someone infected with the hepatitis B virus - people who have lived in parts of the world where hepatitis B is common, including most Asian and Pacific Island nations - people who are exposed to blood or body fluids at work - people on hemodialysis - people whose sex partner(s) has hepatitis B - people who have had more than one sex partner in the last 6 months or have a history of sexually transmitted disease - injection drug users - men who have sex with men |
What is (are) What I need to know about Cirrhosis ? | Cirrhosis* is scarring of the liver. Scar tissue forms because of injury or long-term disease. Scar tissue replaces healthy liver tissue and blocks the normal flow of blood through the liver.
A healthy liver
- makes proteins - helps fight infections - cleans the blood - helps digest food - stores a form of sugar that your body uses for energy
A liver with too much scar tissue cannot work properly. You cannot live without a liver that works. But early treatment can control symptoms and keep cirrhosis from getting worse.
*See the Pronunciation Guide for tips on how to say the words in bold type. |
What causes What I need to know about Cirrhosis ? | Causes of cirrhosis include
- heavy alcohol use - some drugs, medicines, and harmful chemicals - infections - chronic hepatitis B, C, or Dviral infections that attack the liver - autoimmune hepatitis, which causes the bodys immune system to destroy liver cells - nonalcoholic fatty liver disease, which is often caused by obesity - diseases that damage or destroy bile ductstubes that carry bile from the liver
Some inherited diseasesdiseases that are passed from parent to childcan cause cirrhosis:
- hemochromatosis, a disease that causes iron to collect in the liver - Wilson disease, a condition that causes copper to build up in the liver - porphyria, a disorder that affects the skin, bone marrow, and liver |
What are the symptoms of What I need to know about Cirrhosis ? | You may have no symptoms in the early stages of cirrhosis. As cirrhosis gets worse you may
- feel tired or weak - lose your appetite - feel sick to your stomach - lose weight - notice red, spider-shaped blood vessels under your skin
Cirrhosis can lead to other serious problems:
- You may bruise or bleed easily, or have nosebleeds. - Bloating or swelling may occur as fluid builds up in your legs or abdomenthe area between your chest and hips. Fluid buildup in your legs is called edema; buildup in your abdomen is called ascites. - Medicines, including those you can buy over the counter such as vitamins and herbal supplements, may have a stronger effect on you. Your liver does not break medicines down as quickly as a healthy liver would. - Waste materials from food may build up in your blood or brain and cause confusion or difficulty thinking. - Blood pressure may increase in the vein entering your liver, a condition called portal hypertension. - Enlarged veins, called varices, may develop in your esophagus and stomach. Varices can bleed suddenly, causing you to throw up blood or pass blood in a bowel movement. - Your kidneys may not work properly or may fail. - Your skin and the whites of your eyes may turn yellow, a condition called jaundice. - You may develop severe itching. - You may develop gallstones.
In the early stages, cirrhosis causes your liver to swell. Then, as more scar tissue replaces healthy tissue, your liver shrinks.
A small number of people with cirrhosis also get liver cancer. |
How to diagnose What I need to know about Cirrhosis ? | Your doctor will examine you and may perform
- blood tests to see whether your liver is working properly - imaging tests, which may show the size of your liver and show swelling or shrinkage - a liver biopsy, in which a doctor uses a needle to take a small piece of liver tissue to view with a microscope to look for scar tissue |
What are the treatments for What I need to know about Cirrhosis ? | Once you have cirrhosis, nothing can make all the scar tissue go away. But treating the cause will keep cirrhosis from getting worse. For example, if cirrhosis is from heavy alcohol use, the treatment is to completely stop drinking alcohol. If cirrhosis is caused by hepatitis C, then the hepatitis C virus is treated with medicine.
Your doctor will suggest treatment based on the cause of your cirrhosis and your symptoms. Being diagnosed early and carefully following a treatment plan can help many people with cirrhosis. In the late stages of cirrhosis, certain treatments may not be effective. In that case, your doctor will work with you to prevent or manage the problems that cirrhosis can cause.
What if the cirrhosis treatment doesnt work? If too much scar tissue forms, your liver could fail. Then you will need a liver transplant. A liver transplant can return you to good health. For information about liver transplantation, see the booklet What I need to know about Liver Transplantation from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). |

How to prevent What I need to know about Cirrhosis ? | To prevent cirrhosis,
- see your doctor for treatment of your liver disease. Many of the causes of cirrhosis are treatable. Early treatment may prevent cirrhosis. - try to keep your weight in the normal range. Being overweight can make several liver diseases worse. - do not drink any alcohol. Alcohol can harm liver cells. Drinking large amounts of alcohol over many years is one of the major causes of cirrhosis. - do not use illegal drugs, which can increase your chances of getting hepatitis B or hepatitis C. - see your doctor if you have hepatitis. Treatments for hepatitis B, C, and D are available. If you are on treatment, carefully follow your treatment directions. - if you have autoimmune hepatitis, take your medicines and have regular checkups as recommended by your doctor or a liver specialist. |

What is (are) What I need to know about Hirschsprung Disease ? | Hirschsprung* disease (HD) is a disease of the large intestine that causes severe constipation or intestinal obstruction. Constipation means stool moves through the intestines slower than usual. Bowel movements occur less often than normal and stools are difficult to pass. Some children with HD cant pass stool at all, which can result in the complete blockage of the intestines, a condition called intestinal obstruction. People with HD are born with it and are usually diagnosed when they are infants. Less severe cases are sometimes diagnosed when a child is older. An HD diagnosis in an adult is rare.
*See Pronunciation Guide for tips on how to say the words in bold type. |
What is (are) What I need to know about Hirschsprung Disease ? | The large intestine, which includes the colon and rectum, is the last part of the digestive tract. The large intestines main job is to absorb water and hold stool. The rectum connects the colon to the anus. Stool passes out of the body through the anus. At birth, the large intestine is about 2 feet long. An adults large intestine is about 5 feet long. |
What causes What I need to know about Hirschsprung Disease ? | People with HD have constipation because they lack nerve cells in a part or all of the large intestine. The nerve cells signal muscles in the large intestine to push stool toward the anus. Without a signal to push stool along, stool will remain in the large intestine.
How severe HD is depends on how much of the large intestine is affected. Short-segment HD means only the last part of the large intestine lacks nerve cells. Long-segment HD means most or all of the large intestine, and sometimes the last part of the small intestine, lacks nerve cells.
In a person with HD, stool moves through the large intestine until it reaches the part lacking nerve cells. At that point, the stool moves slowly or stops, causing an intestinal obstruction. |
What causes What I need to know about Hirschsprung Disease ? | Before birth, a childs nerve cells normally grow along the intestines in the direction of the anus. With HD, the nerve cells stop growing too soon. Why the nerve cells stop growing is unclear. Some HD is inherited, meaning it is passed from parent to child through genes. HD is not caused by anything a mother did while pregnant. |
What are the symptoms of What I need to know about Hirschsprung Disease ? | The main symptoms of HD are constipation or intestinal obstruction, usually appearing shortly after birth. Constipation in infants and children is common and usually comes and goes, but if your child has had ongoing constipation since birth, HD may be the problem.
Symptoms in Newborns
Newborns with HD almost always fail to have their first bowel movement within 48 hours after birth. Other symptoms include
- green or brown vomit - explosive stools after a doctor inserts a finger into the rectum - swelling of the belly, also known as the abdomen - lots of gas - bloody diarrhea
Symptoms in Toddlers and Older Children
Symptoms of HD in toddlers and older children include
- not being able to pass stools without laxatives or enemas. A laxative is medicine that loosens stool and increases bowel movements. An enema is performed by flushing water, or sometimes a mild soap solution, into the anus using a special wash bottle. - swelling of the abdomen. - lots of gas. - bloody diarrhea. - slow growth or development. - lack of energy because of a shortage of red blood cells, called anemia. |
How to diagnose What I need to know about Hirschsprung Disease ? | HD is diagnosed based on symptoms and test results.
A doctor will perform a physical exam and ask questions about your childs bowel movements. HD is much less likely if parents can identify a time when their childs bowel habits were normal.
If HD is suspected, the doctor will do one or more tests.
X rays
An x ray is a black-and-white picture of the inside of the body. To make the large intestine show up better, the doctor may fill it with barium liquid. Barium liquid is inserted into the large intestine through the anus.
If HD is the problem, the last segment of the large intestine will look narrower than normal. Just before this narrow segment, the intestine will look bulged. The bulging is caused by blocked stool stretching the intestine.
Manometry
During manometry, the doctor inflates a small balloon inside the rectum. Normally, the rectal muscles will relax. If the muscles dont relax, HD may be the problem. This test is most often done in older children and adults.
Biopsy
Biopsy is the most accurate test for HD. The doctor removes a tiny piece of the large intestine and looks at it with a microscope. If nerve cells are missing, HD is the problem. |
What are the treatments for What I need to know about Hirschsprung Disease ? | Pull-through Procedure
HD is treated with surgery called a pull-through procedure. A surgeon removes the segment of the large intestine lacking nerve cells and connects the healthy segment to the anus. The pull-through procedure is usually done soon after diagnosis.
Ostomy surgery
An ostomy allows stool to leave the body through an opening in the abdomen. Although most children with HD do not need an ostomy, a child who has been very sick from HD may need an ostomy to get better before the pull-through procedure.
For ostomy surgery, the surgeon first takes out the diseased segment of the large intestine. The end of the healthy intestine is moved to an opening in the abdomen where a stoma is created. A stoma is created by rolling the intestines end back on itself, like a shirt cuff, and stitching it to the abdominal wall. An ostomy pouch is attached to the stoma and worn outside the body to collect stool. The pouch will need to be emptied several times each day.
If the surgeon removes the entire large intestine and connects the small intestine to the stoma, the surgery is called an ileostomy. If the surgeon leaves part of the large intestine and connects it to the stoma, the surgery is called a colostomy.
Later, during the pull-through procedure, the surgeon removes the stoma and closes the abdomen with stitches. |

What is (are) Mntriers Disease ? | Mntriers disease causes the ridges along the inside of the stomach wallcalled rugaeto enlarge, forming giant folds in the stomach lining. The rugae enlarge because of an overgrowth of mucous cells in the stomach wall.
In a normal stomach, mucous cells in the rugae release protein-containing mucus. The mucous cells in enlarged rugae release too much mucus, causing proteins to leak from the blood into the stomach. This shortage of protein in the blood is known as hypoproteinemia. Mntriers disease also reduces the number of acid-producing cells in the stomach, which decreases stomach acid.
Mntriers disease is also called Mntrier disease or hypoproteinemic hypertrophic gastropathy. |
What causes Mntriers Disease ? | Scientists are unsure about what causes Mntriers disease; however, researchers think that most people acquire, rather than inherit, the disease. In extremely rare cases, siblings have developed Mntriers disease as children, suggesting a genetic link.
Studies suggest that people with Mntriers disease have stomachs that make abnormally high amounts of a protein called transforming growth factor-alpha (TGF-).
TGF- binds to and activates a receptor called epidermal growth factor receptor. Growth factors are proteins in the body that tell cells what to do, such as grow larger, change shape, or divide to make more cells. Researchers have not yet found a cause for the overproduction of TGF-.
Some studies have found cases of people with Mntriers disease who also had Helicobacter pylori (H. pylori) infection. H. pylori is a bacterium that is a cause of peptic ulcers, or sores on the lining of the stomach or the duodenum, the first part of the small intestine. In these cases, treatment for H. pylori reversed and improved the symptoms of Mntriers disease.1
Researchers have linked some cases of Mntriers disease in children to infection with cytomegalovirus (CMV). CMV is one of the herpes viruses. This group of viruses includes the herpes simplex viruses, which cause chickenpox, shingles, and infectious mononucleosis, also known as mono. Most healthy children and adults infected with CMV have no symptoms and may not even know they have an infection. However, in people with a weakened immune system, CMV can cause serious disease, such as retinitis, which can lead to blindness.
Researchers are not sure how H. pylori and CMV infections contribute to the development of Mntriers disease. |
Who is at risk for Mntriers Disease? ? | Mntriers disease is rare. The disease is more common in men than in women. The average age at diagnosis is 55.2 |
What are the symptoms of Mntriers Disease ? | The most common symptom of Mntriers disease is pain in the upper middle part of the abdomen. The abdomen is the area between the chest and hips.
Other signs and symptoms of Mntriers disease may include
- nausea and frequent vomiting - diarrhea - loss of appetite - extreme weight loss - malnutrition - low levels of protein in the blood - swelling of the face, abdomen, limbs, and feet due to low levels of protein in the blood - anemiatoo few red blood cells in the body, which prevents the body from getting enough oxygendue to bleeding in the stomach
People with Mntriers disease have a higher chance of developing stomach cancer, also called gastric cancer. |
How to diagnose Mntriers Disease ? | Health care providers base the diagnosis of Mntriers disease on a combination of symptoms, lab findings, findings on upper gastrointestinal (GI) endoscopy, and stomach biopsy results. A health care provider will begin the diagnosis of Mntriers disease by taking a patients medical and family history and performing a physical exam. However, a health care provider will confirm the diagnosis of Mntriers disease through a computerized tomography (CT) scan, an upper GI endoscopy, and a biopsy of stomach tissue. A health care provider also may order blood tests to check for infection with H. pylori or CMV.
Medical and family history. Taking a medical and family history is one of the first things a health care provider may do to help diagnose Mntriers disease. He or she will ask the patient to provide a medical and family history.
Physical exam. A physical exam may help diagnose Mntriers disease. During a physical exam, a health care provider usually
- examines a patients body - uses a stethoscope to listen to bodily sounds - taps on specific areas of the patients body
CT scan. CT scans use a combination of x rays and computer technology to create images. For a CT scan, a health care provider may give the patient a solution to drink and an injection of a special dye, called contrast medium. CT scans require the patient to lie on a table that slides into a tunnel-shaped device where an x-ray technician takes x rays. An x-ray technician performs the procedure in an outpatient center or a hospital, and a radiologista doctor who specializes in medical imaginginterprets them. The patient does not need anesthesia. CT scans can show enlarged folds in the stomach wall.
Upper GI endoscopy. This procedure involves using an endoscopea small, flexible tube with a lightto see the upper GI tract, which includes the esophagus, stomach, and duodenum. A gastroenterologista doctor who specializes in digestive diseasesperforms the test at a hospital or an outpatient center. The gastroenterologist carefully feeds the endoscope down the esophagus and into the stomach. A small camera mounted on the endoscope transmits a video image to a monitor, allowing close examination of the stomach lining. The gastroenterologist also can take a biopsy of the stomach tissue during the endoscopy. A health care provider may give a patient a liquid anesthetic to gargle or may spray anesthetic on the back of the patients throat. A health care provider will place an intravenous (IV) needle in a vein in the arm to administer sedation. Sedatives help patients stay relaxed and comfortable. The test can show enlarged folds in the stomach wall.
Biopsy. Biopsy is a procedure that involves taking a piece of stomach tissue for examination with a microscope. A gastroenterologist performs the biopsy at the time of upper GI endoscopy. A pathologista doctor who specializes in diagnosing diseasesexamines the stomach tissue in a lab. The test can diagnose Mntriers disease by showing changes in the stomachs mucous cells and acid-producing cells.
Blood test. A health care provider will take a blood sample that can show the presence of infection with H. pylori or CMV. A blood test involves drawing blood at a health care providers office or a commercial facility and sending the sample to a lab for analysis. |
What are the treatments for Mntriers Disease ? | Treatment may include medications, IV protein, blood transfusions, and surgery.
Medications
Health care providers may prescribe the anticancer medication cetuximab (Erbitux) to treat Mntriers disease. Studies have shown that cetuximab blocks the activity of epidermal growth factor receptor and can significantly improve a persons symptoms, as well as decrease the thickness of the stomach wall from the overgrowth of mucous cells. A person receives cetuximab by IV in a health care providers office or an outpatient center. Studies to assess the effectiveness of cetuximab to treat Mntriers disease are ongoing. A health care provider also may prescribe medications to relieve nausea and abdominal pain.
In people with Mntriers disease who also have H. pylori or CMV infection, treatment of the infection may improve symptoms. Health care providers prescribe antibiotics to kill H. pylori. Antibiotic regimens may differ throughout the world because some strains of H. pylori have become resistant to certain antibioticsmeaning that an antibiotic that once destroyed the bacterium is no longer effective. Health care providers use antiviral medications to treat CMV infection in a person with a weakened immune system in order to prevent a serious disease from developing as a result of CMV. Antiviral medications cannot kill CMV; however, they can slow down the virus reproduction.
Intravenous Protein and Blood Transfusions
A health care provider may recommend an IV treatment of protein and a blood transfusion to a person who is malnourished or anemic because of Mntriers disease. In most cases of children with Mntriers disease who also have had CMV infection, treatment with protein and a blood transfusion led to a full recovery.
Surgery
If a person has severe Mntriers disease with significant protein loss, a surgeon may need to remove part or all of the stomach in a surgery called gastrectomy.
Surgeons perform gastrectomy in a hospital. The patient will require general anesthesia. Some surgeons perform a gastrectomy through laparoscopic surgery rather than through a wide incision in the abdomen. In laparoscopic surgery, the surgeon uses several smaller incisions and feeds special surgical tools through the incisions to remove the diseased part of the stomach. After gastrectomy, the surgeon may reconstruct the changed portions of the GI tract so that it may continue to function. Usually the surgeon attaches the small intestine to any remaining portion of the stomach or to the esophagus if he or she removed the entire stomach. |
What to do for Mntriers Disease ? | Researchers have not found that eating, diet, and nutrition play a role in causing or preventing Mntriers disease. In some cases, a health care provider may prescribe a high-protein diet to offset the loss of protein due to Mntriers disease. Some people with severe malnutrition may require IV nutrition, which is called total parenteral nutrition (TPN). TPN is a method of providing an IV liquid food mixture through a special tube in the chest. |

What is (are) Goodpasture Syndrome ? | Goodpasture syndrome is a pulmonary-renal syndrome, which is a group of acute illnesses involving the kidneys and lungs. Goodpasture syndrome includes all of the following conditions:
- glomerulonephritisinflammation of the glomeruli, which are tiny clusters of looping blood vessels in the kidneys that help filter wastes and extra water from the blood - the presence of anti-glomerular basement membrane (GBM) antibodies; the GBM is part of the glomeruli and is composed of collagen and other proteins - bleeding in the lungs
In Goodpasture syndrome, immune cells produce antibodies against a specific region of collagen. The antibodies attack the collagen in the lungs and kidneys.
Ernest Goodpasture first described the syndrome during the influenza pandemic of 1919 when he reported on a patient who died from bleeding in the lungs and kidney failure. Diagnostic tools to confirm Goodpasture syndrome were not available at that time, so it is not known whether the patient had true Goodpasture syndrome or vasculitis. Vasculitis is an autoimmune conditiona disorder in which the bodys immune system attacks the bodys own cells and organsthat involves inflammation in the blood vessels and can cause similar lung and kidney problems.
Goodpasture syndrome is sometimes called anti-GBM disease. However, anti-GBM disease is only one cause of pulmonary-renal syndromes, including Goodpasture syndrome.
Goodpasture syndrome is fatal unless quickly diagnosed and treated. |
What causes Goodpasture Syndrome ? | The causes of Goodpasture syndrome are not fully understood. People who smoke or use hair dyes appear to be at increased risk for this condition. Exposure to hydrocarbon fumes, metallic dust, and certain drugs, such as cocaine, may also raise a persons risk. Genetics may also play a part, as a small number of cases have been reported in more than one family member. |
What are the symptoms of Goodpasture Syndrome ? | The symptoms of Goodpasture syndrome may initially include fatigue, nausea, vomiting, and weakness. The lungs are usually affected before or at the same time as the kidneys, and symptoms can include shortness of breath and coughing, sometimes with blood. The progression from initial symptoms to the lungs being affected may be very rapid. Symptoms that occur when the kidneys are affected include blood in the urine or foamy urine, swelling in the legs, and high blood pressure. |
How to diagnose Goodpasture Syndrome ? | A health care provider may order the following tests to diagnose Goodpasture syndrome:
- Urinalysis. Urinalysis is testing of a urine sample. The urine sample is collected in a special container in a health care providers office or commercial facility and can be tested in the same location or sent to a lab for analysis. For the test, a nurse or technician places a strip of chemically treated paper, called a dipstick, into the urine. Patches on the dipstick change color when protein or blood are present in urine. A high number of red blood cells and high levels of protein in the urine indicate kidney damage. - Blood test. A blood test involves drawing blood at a health care providers office or commercial facility and sending the sample to a lab for analysis. The blood test can show the presence of anti-GBM antibodies. - Chest x ray. An x ray of the chest is performed in a health care providers office, outpatient center, or hospital by an x-ray technician, and the images are interpreted by a radiologista doctor who specializes in medical imaging. Abnormalities in the lungs, if present, can be seen on the x ray. - Biopsy. A biopsy is a procedure that involves taking a piece of kidney tissue for examination with a microscope. The biopsy is performed by a health care provider in a hospital with light sedation and local anesthetic. The health care provider uses imaging techniques such as ultrasound or a computerized tomography scan to guide the biopsy needle into the kidney. The tissue is examined in a lab by a pathologista doctor who specializes in diagnosing diseases. The test can show crescent-shaped changes in the glomeruli and lines of antibodies attached to the GBM. |
What are the treatments for Goodpasture Syndrome ? | Goodpasture syndrome is usually treated with
- immunosuppressive medications, such as cyclophosphamide, to keep the immune system from making antibodies - corticosteroid medications to suppress the bodys autoimmune response - plasmapheresisa procedure that uses a machine to remove blood from the body, separate certain cells from the plasma, and return just the cells to the persons body; the anti-GBM antibodies remain in the plasma and are not returned to the persons body
Plasmapheresis is usually continued for several weeks, and immunosuppressive medications may be given for 6 to 12 months, depending on the response to therapy. In most cases, bleeding in the lungs stops and no permanent lung damage occurs. Damage to the kidneys, however, may be long lasting. If the kidneys fail, blood-filtering treatments called dialysis or kidney transplantation may become necessary. |

What is (are) Diabetes, Heart Disease, and Stroke ? | Diabetes is a disorder of metabolismthe way our bodies use digested food for energy. Most of the food we eat is broken down into glucose, the form of sugar in the blood. Glucose is the body's main source of fuel.
After digestion, glucose enters the bloodstream. Then glucose goes to cells throughout the body where it is used for energy. However, a hormone called insulin must be present to allow glucose to enter the cells. Insulin is a hormone produced by the pancreas, a large gland behind the stomach.
In people who do not have diabetes, the pancreas automatically produces the right amount of insulin to move glucose from blood into the cells. However, diabetes develops when the pancreas does not make enough insulin, or the cells in the muscles, liver, and fat do not use insulin properly, or both. As a result, the amount of glucose in the blood increases while the cells are starved of energy.
Over time, high blood glucose levels damage nerves and blood vessels, leading to complications such as heart disease and stroke, the leading causes of death among people with diabetes. Uncontrolled diabetes can eventually lead to other health problems as well, such as vision loss, kidney failure, and amputations. |
What is (are) Diabetes, Heart Disease, and Stroke ? | Prediabetes is a condition in which blood glucose levels are higher than normal but not high enough for a diagnosis of diabetes. Prediabetes is also called impaired fasting glucose or impaired glucose tolerance. Many people with prediabetes develop type 2 diabetes within 10 years. In addition, they are at risk for heart disease and stroke. With modest weight loss and moderate physical activity, people with prediabetes can delay or prevent type 2 diabetes and lower their risk of heart disease and stroke. |
What is (are) Diabetes, Heart Disease, and Stroke ? | If you have diabetes, you are at least twice as likely as someone who does not have diabetes to have heart disease or a stroke. People with diabetes also tend to develop heart disease or have strokes at an earlier age than other people. If you are middle-aged and have type 2 diabetes, some studies suggest that your chance of having a heart attack is as high as someone without diabetes who has already had one heart attack. Women who have not gone through menopause usually have less risk of heart disease than men of the same age. But women of all ages with diabetes have an increased risk of heart disease because diabetes cancels out the protective effects of being a woman in her child-bearing years.
People with diabetes who have already had one heart attack run an even greater risk of having a second one. In addition, heart attacks in people with diabetes are more serious and more likely to result in death. High blood glucose levels over time can lead to increased deposits of fatty materials on the insides of the blood vessel walls. These deposits may affect blood flow, increasing the chance of clogging and hardening of blood vessels (atherosclerosis). |

Who is at risk for Diabetes, Heart Disease, and Stroke? ? | Diabetes itself is a risk factor for heart disease and stroke. Also, many people with diabetes have other conditions that increase their chance of developing heart disease and stroke. These conditions are called risk factors. One risk factor for heart disease and stroke is having a family history of heart disease. If one or more members of your family had a heart attack at an early age (before age 55 for men or 65 for women), you may be at increased risk.
You can't change whether heart disease runs in your family, but you can take steps to control the other risk factors for heart disease listed here:
- Having central obesity. Central obesity means carrying extra weight around the waist, as opposed to the hips. A waist measurement of more than 40 inches for men and more than 35 inches for women means you have central obesity. Your risk of heart disease is higher because abdominal fat can increase the production of LDL (bad) cholesterol, the type of blood fat that can be deposited on the inside of blood vessel walls. - Having abnormal blood fat (cholesterol) levels. - LDL cholesterol can build up inside your blood vessels, leading to narrowing and hardening of your arteriesthe blood vessels that carry blood from the heart to the rest of the body. Arteries can then become blocked. Therefore, high levels of LDL cholesterol raise your risk of getting heart disease. - Triglycerides are another type of blood fat that can raise your risk of heart disease when the levels are high. - HDL (good) cholesterol removes deposits from inside your blood vessels and takes them to the liver for removal. Low levels of HDL cholesterol increase your risk for heart disease. - Having high blood pressure. If you have high blood pressure, also called hypertension, your heart must work harder to pump blood. High blood pressure can strain the heart, damage blood vessels, and increase your risk of heart attack, stroke, eye problems, and kidney problems. - Smoking. Smoking doubles your risk of getting heart disease. Stopping smoking is especially important for people with diabetes because both smoking and diabetes narrow blood vessels. Smoking also increases the risk of other long-term complications, such as eye problems. In addition, smoking can damage the blood vessels in your legs and increase the risk of amputation. |
What is (are) Diabetes, Heart Disease, and Stroke ? | Metabolic syndrome is a grouping of traits and medical conditions that puts people at risk for both heart disease and type 2 diabetes. It is defined by the National Cholesterol Education Program as having any three of the following five traits and medical conditions:
Traits and Medical Conditions Definition Elevated waist circumference Waist measurement of - 40 inches or more in men - 35 inches or more in women Elevated levels of triglycerides - 150 mg/dL or higher or Taking medication for elevated triglyceride levels Low levels of HDL (good) cholesterol - Below 40 mg/dL in men - Below 50 mg/dL in women or Taking medication for low HDL cholesterol levels Elevated blood pressure levels - 130 mm Hg or higher for systolic blood pressure or - 85 mm Hg or higher for diastolic blood pressure or Taking medication for elevated blood pressure levels Elevated fasting blood glucose levels - 100 mg/dL or higher or Taking medication for elevated blood glucose levels |
How to prevent Diabetes, Heart Disease, and Stroke ? | Even if you are at high risk for heart disease and stroke, you can help keep your heart and blood vessels healthy. You can do so by taking the following steps:
- Make sure that your diet is "heart-healthy." Meet with a registered dietitian to plan a diet that meets these goals: - Include at least 14 grams of fiber daily for every 1,000 calories consumed. Foods high in fiber may help lower blood cholesterol. Oat bran, oatmeal, whole-grain breads and cereals, dried beans and peas (such as kidney beans, pinto beans, and black-eyed peas), fruits, and vegetables are all good sources of fiber. Increase the amount of fiber in your diet gradually to avoid digestive problems. - Cut down on saturated fat. It raises your blood cholesterol level. Saturated fat is found in meats, poultry skin, butter, dairy products with fat, shortening, lard, and tropical oils such as palm and coconut oil. Your dietitian can figure out how many grams of saturated fat should be your daily maximum amount. - Keep the cholesterol in your diet to less than 300 milligrams a day. Cholesterol is found in meat, dairy products, and eggs. - Keep the amount of trans fat in your diet to a minimum. It's a type of fat in foods that raises blood cholesterol. Limit your intake of crackers, cookies, snack foods, commercially prepared baked goods, cake mixes, microwave popcorn, fried foods, salad dressings, and other foods made with partially hydrogenated oil. In addition, some kinds of vegetable shortening and margarines have trans fat. Check for trans fat in the Nutrition Facts section on the food package. - If you smoke, quit. Your doctor can help you find ways to quit smoking. - Ask your doctor whether you should take aspirin. Studies have shown that taking a low dose of aspirin every day can help reduce the risk of heart disease and stroke. However, aspirin is not safe for everyone. Your doctor can tell you whether taking aspirin is right for you and exactly how much to take. - Get prompt treatment for transient ischemic attacks (TIAs). Early treatment for TIAs, sometimes called mini-strokes, may help prevent or delay a future stroke. Signs of a TIA are sudden weakness, loss of balance, numbness, confusion, blindness in one or both eyes, double vision, difficulty speaking, or a severe headache. |
What are the treatments for Diabetes, Heart Disease, and Stroke ? | You can keep track of the ABCs of diabetes to make sure your treatment is working. Talk with your health care provider about the best targets for you.
A stands for A1C (a test that measures blood glucose control). Have an A1C test at least twice a year. It shows your average blood glucose level over the past 3 months. Talk with your doctor about whether you should check your blood glucose at home and how to do it.
A1C target Below 7 percent, unless your doctor sets a different target
Blood glucose targets Before meals 90 to 130 mg/dL 1 to 2 hours after the start of a meal Less than 180 mg/dL
B is for blood pressure. Have it checked at every office visit.
Blood pressure target Below 140/80 mm Hg, unless your doctor sets a different target
C is for cholesterol. Have it checked at least once a year.
Blood fat (cholesterol) targets LDL (bad) cholesterol Under 100 mg/dL Triglycerides Under 150 mg/dL HDL (good) cholesterol For men: above 40 mg/dL For women: above 50 mg/dL
Control of the ABCs of diabetes can reduce your risk for heart disease and stroke. If your blood glucose, blood pressure, and cholesterol levels aren't on target, ask your doctor what changes in diet, activity, and medications can help you reach these goals. |
What is (are) Diabetes, Heart Disease, and Stroke ? | Two major types of heart and blood vessel disease, also called cardiovascular disease, are common in people with diabetes: coronary artery disease (CAD) and cerebral vascular disease. People with diabetes are also at risk for heart failure. Narrowing or blockage of the blood vessels in the legs, a condition called peripheral arterial disease, can also occur in people with diabetes.
Coronary Artery Disease
Coronary artery disease, also called ischemic heart disease, is caused by a hardening or thickening of the walls of the blood vessels that go to your heart. Your blood supplies oxygen and other materials your heart needs for normal functioning. If the blood vessels to your heart become narrowed or blocked by fatty deposits, the blood supply is reduced or cut off, resulting in a heart attack.
Cerebral Vascular Disease
Cerebral vascular disease affects blood flow to the brain, leading to strokes and TIAs. It is caused by narrowing, blocking, or hardening of the blood vessels that go to the brain or by high blood pressure.
Stroke
A stroke results when the blood supply to the brain is suddenly cut off, which can occur when a blood vessel in the brain or neck is blocked or bursts. Brain cells are then deprived of oxygen and die. A stroke can result in problems with speech or vision or can cause weakness or paralysis. Most strokes are caused by fatty deposits or blood clotsjelly-like clumps of blood cellsthat narrow or block one of the blood vessels in the brain or neck. A blood clot may stay where it formed or can travel within the body. People with diabetes are at increased risk for strokes caused by blood clots.
A stroke may also be caused by a bleeding blood vessel in the brain. Called an aneurysm, a break in a blood vessel can occur as a result of high blood pressure or a weak spot in a blood vessel wall.
TIAs
TIAs are caused by a temporary blockage of a blood vessel to the brain. This blockage leads to a brief, sudden change in brain function, such as temporary numbness or weakness on one side of the body. Sudden changes in brain function also can lead to loss of balance, confusion, blindness in one or both eyes, double vision, difficulty speaking, or a severe headache. However, most symptoms disappear quickly and permanent damage is unlikely. If symptoms do not resolve in a few minutes, rather than a TIA, the event could be a stroke. The occurrence of a TIA means that a person is at risk for a stroke sometime in the future. See page 3 for more information on risk factors for stroke.
Heart Failure
Heart failure is a chronic condition in which the heart cannot pump blood properlyit does not mean that the heart suddenly stops working. Heart failure develops over a period of years, and symptoms can get worse over time. People with diabetes have at least twice the risk of heart failure as other people. One type of heart failure is congestive heart failure, in which fluid builds up inside body tissues. If the buildup is in the lungs, breathing becomes difficult.
Blockage of the blood vessels and high blood glucose levels also can damage heart muscle and cause irregular heart beats. People with damage to heart muscle, a condition called cardiomyopathy, may have no symptoms in the early stages, but later they may experience weakness, shortness of breath, a severe cough, fatigue, and swelling of the legs and feet. Diabetes can also interfere with pain signals normally carried by the nerves, explaining why a person with diabetes may not experience the typical warning signs of a heart attack.
Peripheral Arterial Disease
Another condition related to heart disease and common in people with diabetes is peripheral arterial disease (PAD). With this condition, the blood vessels in the legs are narrowed or blocked by fatty deposits, decreasing blood flow to the legs and feet. PAD increases the chances of a heart attack or stroke occurring. Poor circulation in the legs and feet also raises the risk of amputation. Sometimes people with PAD develop pain in the calf or other parts of the leg when walking, which is relieved by resting for a few minutes. |
What are the treatments for Diabetes, Heart Disease, and Stroke ? | Treatment for heart disease includes meal planning to ensure a heart-healthy diet and physical activity. In addition, you may need medications to treat heart damage or to lower your blood glucose, blood pressure, and cholesterol. If you are not already taking a low dose of aspirin every day, your doctor may suggest it. You also may need surgery or some other medical procedure.
For additional information about heart and blood vessel disease, high blood pressure, and high cholesterol, call the National Heart, Lung, and Blood Institute Health Information Center at 3015928573 or see www.nhlbi.nih.gov on the Internet. |
What are the treatments for Diabetes, Heart Disease, and Stroke ? | At the first sign of a stroke, you should get medical care right away. If blood vessels to your brain are blocked by blood clots, the doctor can give you a "clot-busting" drug. The drug must be given soon after a stroke to be effective. Subsequent treatment for stroke includes medications and physical therapy, as well as surgery to repair the damage. Meal planning and physical activity may be part of your ongoing care. In addition, you may need medications to lower your blood glucose, blood pressure, and cholesterol and to prevent blood clots.

What is (are) Hypothyroidism ? | Hypothyroidism is a disorder that occurs when the thyroid gland does not make enough thyroid hormone to meet the bodys needs. Thyroid hormone regulates metabolismthe way the body uses energyand affects nearly every organ in the body. Without enough thyroid hormone, many of the bodys functions slow down. About 4.6 percent of the U.S. population age 12 and older has hypothyroidism.1 |
What is (are) Hypothyroidism ? | The thyroid is a 2-inch-long, butterfly-shaped gland weighing less than 1 ounce. Located in the front of the neck below the larynx, or voice box, it has two lobes, one on each side of the windpipe. The thyroid is one of the glands that make up the endocrine system. The glands of the endocrine system produce and store hormones and release them into the bloodstream. The hormones then travel through the body and direct the activity of the bodys cells.
The thyroid gland makes two thyroid hormones, triiodothyronine (T3) and thyroxine (T4). T3 is made from T4 and is the more active hormone, directly affecting the tissues. Thyroid hormones affect metabolism, brain development, breathing, heart and nervous system functions, body temperature, muscle strength, skin dryness, menstrual cycles, weight, and cholesterol levels. |
What causes Hypothyroidism ? | Hypothyroidism has several causes, including
- Hashimotos disease - thyroiditis, or inflammation of the thyroid - congenital hypothyroidism, or hypothyroidism that is present at birth - surgical removal of part or all of the thyroid - radiation treatment of the thyroid - some medications
Less commonly, hypothyroidism is caused by too much or too little iodine in the diet or by abnormalities of the pituitary gland.
Hashimotos Disease
Hashimotos disease, also called chronic lymphocytic thyroiditis, is the most common cause of hypothyroidism in the United States.1 Hashimotos disease is a form of chronic inflammation of the thyroid gland. Hashimotos disease is also an autoimmune disorder.
Normally, the immune system protects the body against foreign invaderssuch as viruses and bacteriathat can cause illness. But in autoimmune diseases, the immune system attacks the bodys own cells and organs. With Hashimotos disease, the immune system attacks the thyroid, causing inflammation and interfering with its ability to produce thyroid hormones.
More information is provided in the NIDDK health topic, Hashimotos Disease.
Thyroiditis
Thyroiditis causes stored thyroid hormone to leak out of the thyroid gland. At first, the leakage raises hormone levels in the blood, leading to hyperthyroidismwhen thyroid hormone levels are too highthat lasts for 1 or 2 months. Most people then develop hypothyroidism before the thyroid is completely healed.
Several types of thyroiditis can cause hyperthyroidism followed by hypothyroidism:
- Subacute thyroiditis. This condition involves painful inflammation and enlargement of the thyroid. Experts are not sure what causes subacute thyroiditis, but it may be related to a viral or bacterial infection. The condition usually goes away on its own in a few months. - Postpartum thyroiditis. This type of thyroiditis develops after a woman gives birth. For more information, see the section titled What happens with pregnancy and thyroid conditions? - Silent thyroiditis. This type of thyroiditis is called silent because it is painless, as is postpartum thyroiditis, even though the thyroid may be enlarged. Like postpartum thyroiditis, silent thyroiditis is probably an autoimmune condition and sometimes develops into permanent hypothyroidism.
Congenital Hypothyroidism
Some babies are born with a thyroid that is not fully developed or does not function properly. If untreated, congenital hypothyroidism can lead to mental retardation and growth failure. Early treatment can prevent these complications, so most newborns in the United States are screened for hypothyroidism.
Surgical Removal of the Thyroid
When part of the thyroid is removed, the remaining part may produce normal amounts of thyroid hormone, but some people who have this surgery develop hypothyroidism. Removal of the entire thyroid always results in hypothyroidism.
Part or all of the thyroid may be surgically removed as a treatment for
- hyperthyroidism - a large goiter, which is an enlarged thyroid that may cause the neck to appear swollen and can interfere with normal breathing and swallowing - thyroid nodules, which are noncancerous tumors, called adenomas, or lumps in the thyroid that can produce excess thyroid hormone - thyroid cancer
Radiation Treatment of the Thyroid
Radioactive iodine, a common treatment for hyperthyroidism, gradually destroys the cells of the thyroid. Most people who receive radioactive iodine treatment eventually develop hypothyroidism. People with Hodgkins disease, other lymphomas, and head or neck cancers are treated with radiation, which can also damage the thyroid.
Medications
Some drugs can interfere with thyroid hormone production and lead to hypothyroidism, including
- amiodarone, a heart medication - interferon alpha, a cancer medication - lithium, a bipolar disorder medication - interleukin-2, a kidney cancer medication |
What are the symptoms of Hypothyroidism ? | Hypothyroidism has many symptoms that can vary from person to person. Some common symptoms of hypothyroidism are
- fatigue - weight gain - a puffy face - cold intolerance - joint and muscle pain - constipation - dry skin - dry, thinning hair - decreased sweating - heavy or irregular menstrual periods and impaired fertility - depression - slowed heart rate
However, hypothyroidism develops slowly, so many people dont notice symptoms of the disease.
Symptoms more specific to Hashimotos disease are a goiter and a feeling of fullness in the throat.
Hypothyroidism can contribute to high cholesterol, so people with high cholesterol should be tested for hypothyroidism. Rarely, severe, untreated hypothyroidism may lead to myxedema coma, an extreme form of hypothyroidism in which the bodys functions slow to the point that it becomes life threatening. Myxedema requires immediate medical treatment. |
How to diagnose Hypothyroidism ? | Many symptoms of hypothyroidism are the same as those of other diseases, so hypothyroidism usually cannot be diagnosed based on symptoms alone. With suspected hypothyroidism, health care providers take a medical history and perform a thorough physical examination. Health care providers may then use several blood tests to confirm a diagnosis of hypothyroidism and find its cause:
TSH test. The ultrasensitive TSH test is usually the first test a health care provider performs. This test detects even tiny amounts of TSH in the blood and is the most accurate measure of thyroid activity available. Generally, a TSH reading above normal means a person has hypothyroidism and a reading below normal means a person has hyperthyroidism.
Mildly elevated TSH without symptoms indicates subclinical hypothyroidism. Some health care providers treat subclinical hypothyroidism immediately. Others prefer to leave it untreated but monitor their patients for signs that the condition is worsening.
Health care providers may conduct additional tests to help confirm the diagnosis or determine the cause of hypothyroidism.
T4 test. This test measures the actual amount of circulating thyroid hormone in the blood. In hypothyroidism, the level of T4 in the blood is lower than normal.
Thyroid autoantibody test. This test looks for the presence of thyroid autoantibodies. Most people with Hashimotos disease have these antibodies, but people whose hypothyroidism is caused by other conditions do not.
More information about testing for thyroid problems is provided in the NIDDK health topic, Thyroid Tests. |
What are the treatments for Hypothyroidism ? | Health care providers treat hypothyroidism with synthetic thyroxine, a medication that is identical to the hormone T4. The exact dose will depend on the patients age and weight, the severity of the hypothyroidism, the presence of other health problems, and whether the person is taking other drugs that might interfere with how well the body uses thyroid hormone.
Health care providers test TSH levels about 6 to 8 weeks after a patient begins taking thyroid hormone and make any necessary adjustments to the dose. Each time the dose is adjusted, the blood is tested again. Once a stable dose is reached, blood tests are normally repeated in 6 months and then once a year.
Hypothyroidism can almost always be completely controlled with synthetic thyroxine, as long as the recommended dose is taken every day as instructed. |
What to do for Hypothyroidism ? | Experts recommend that people eat a balanced diet to obtain most nutrients. More information about diet and nutrition can be found on the National Agricultural Library website at www.nutrition.gov.
Dietary Supplements
Iodine is an essential mineral for the thyroid. However, people with autoimmune thyroid disease may be sensitive to harmful side effects from iodine. Taking iodine drops or eating foods containing large amounts of iodinesuch as seaweed, dulse, or kelpmay cause or worsen hypothyroidism or hyperthyroidism. More information about iodine can be found in the National Library of Medicine fact sheet Iodine in diet, available at www.nlm.nih.gov/medlineplus/ency/article/002421.htm.
Women need more iodine when they are pregnantabout 250 micrograms a day because the baby gets iodine from the mothers diet. In the United States, about 7 percent of pregnant women may not get enough iodine in their diet or through prenatal vitamins.3 Choosing iodized salt salt supplemented with iodineover plain salt and prenatal vitamins containing iodine will ensure this need is met.
To help ensure coordinated and safe care, people should discuss their use of dietary supplements, such as iodine, with their health care provider. Tips for talking with health care providers are available through the National Center for Complementary and Integrative Health. |

What is (are) Adrenal Insufficiency and Addison's Disease ? | Adrenal insufficiency is an endocrine, or hormonal, disorder that occurs when the adrenal glands do not produce enough of certain hormones. The adrenal glands are located just above the kidneys.
Adrenal insufficiency can be primary or secondary. Addisons disease, the common term for primary adrenal insufficiency, occurs when the adrenal glands are damaged and cannot produce enough of the adrenal hormone cortisol. The adrenal hormone aldosterone may also be lacking. Addisons disease affects 110 to 144 of every 1 million people in developed countries.1
Secondary adrenal insufficiency occurs when the pituitary glanda pea-sized gland at the base of the brainfails to produce enough adrenocorticotropin (ACTH), a hormone that stimulates the adrenal glands to produce the hormone cortisol. If ACTH output is too low, cortisol production drops. Eventually, the adrenal glands can shrink due to lack of ACTH stimulation. Secondary adrenal insufficiency is much more common than Addisons disease.
1 |
What are the symptoms of Adrenal Insufficiency and Addison's Disease ? | Adrenal Insufficiency
The most common symptoms of adrenal insufficiency are
- chronic, or long lasting, fatigue - muscle weakness - loss of appetite - weight loss - abdominal pain
Other symptoms of adrenal insufficiency can include
- nausea - vomiting - diarrhea - low blood pressure that drops further when a person stands up, causing dizziness or fainting - irritability and depression - craving salty foods - hypoglycemia, or low blood sugar - headache - sweating - irregular or absent menstrual periods - in women, loss of interest in sex
Hyperpigmentation, or darkening of the skin, can occur in Addisons disease, although not in secondary adrenal insufficiency. This darkening is most visible on scars; skin folds; pressure points such as the elbows, knees, knuckles, and toes; lips; and mucous membranes such as the lining of the cheek.
The slowly progressing symptoms of adrenal insufficiency are often ignored until a stressful event, such as surgery, a severe injury, an illness, or pregnancy, causes them to worsen.
Adrenal Crisis
Sudden, severe worsening of adrenal insufficiency symptoms is called adrenal crisis. If the person has Addisons disease, this worsening can also be called an Addisonian crisis. In most cases, symptoms of adrenal insufficiency become serious enough that people seek medical treatment before an adrenal crisis occurs. However, sometimes symptoms appear for the first time during an adrenal crisis.
Symptoms of adrenal crisis include
- sudden, severe pain in the lower back, abdomen, or legs - severe vomiting and diarrhea - dehydration - low blood pressure - loss of consciousness
If not treated, an adrenal crisis can cause death.
Get Treatment for Adrenal Crisis Right Away People with adrenal insufficiency who have weakness, nausea, or vomiting need immediate emergency treatment to prevent an adrenal crisis and possible death. An injection with a synthetic glucocorticoid hormone called a corticosteroid can save a persons life. People should make sure to have a corticosteroid injection with them at all times, and make sure their friends and family know how and when to give the injection.

What causes Adrenal Insufficiency and Addison's Disease ? | Autoimmune disorders cause most cases of Addisons disease. Infections and medications may also cause the disease.
Autoimmune Disorders
Up to 80 percent of Addisons disease cases are caused by an autoimmune disorder, which is when the bodys immune system attacks the bodys own cells and organs.2 In autoimmune Addisons, which mainly occurs in middle-aged females, the immune system gradually destroys the adrenal cortexthe outer layer of the adrenal glands.2
Primary adrenal insufficiency occurs when at least 90 percent of the adrenal cortex has been destroyed.1 As a result, both cortisol and aldosterone are often lacking. Sometimes only the adrenal glands are affected. Sometimes other endocrine glands are affected as well, as in polyendocrine deficiency syndrome.
Polyendocrine deficiency syndrome is classified into type 1 and type 2. Type 1 is inherited and occurs in children. In addition to adrenal insufficiency, these children may have
- underactive parathyroid glands, which are four pea-sized glands located on or near the thyroid gland in the neck; they produce a hormone that helps maintain the correct balance of calcium in the body. - slow sexual development. - pernicious anemia, a severe type of anemia; anemia is a condition in which red blood cells are fewer than normal, which means less oxygen is carried to the bodys cells. With most types of anemia, red blood cells are smaller than normal; however, in pernicious anemia, the cells are bigger than normal. - chronic fungal infections. - chronic hepatitis, a liver disease.
Researchers think type 2, which is sometimes called Schmidts syndrome, is also inherited. Type 2 usually affects young adults and may include
- an underactive thyroid gland, which produces hormones that regulate metabolism - slow sexual development - diabetes, in which a person has high blood glucose, also called high blood sugar or hyperglycemia - vitiligo, a loss of pigment on areas of the skin
Infections
Tuberculosis (TB), an infection that can destroy the adrenal glands, accounts for 10 to 15 percent of Addisons disease cases in developed countries.1 When primary adrenal insufficiency was first identified by Dr. Thomas Addison in 1849, TB was the most common cause of the disease. As TB treatment improved, the incidence of Addisons disease due to TB of the adrenal glands greatly decreased. However, recent reports show an increase in Addisons disease from infections such as TB and cytomegalovirus. Cytomegalovirus is a common virus that does not cause symptoms in healthy people; however, it does affect babies in the womb and people who have a weakened immune systemmostly due to HIV/AIDS.2 Other bacterial infections, such as Neisseria meningitidis, which is a cause of meningitis, and fungal infections can also lead to Addisons disease.
Other Causes
Less common causes of Addisons disease are
- cancer cells in the adrenal glands - amyloidosis, a serious, though rare, group of diseases that occurs when abnormal proteins, called amyloids, build up in the blood and are deposited in tissues and organs - surgical removal of the adrenal glands - bleeding into the adrenal glands - genetic defects including abnormal adrenal gland development, an inability of the adrenal glands to respond to ACTH, or a defect in adrenal hormone production - medication-related causes, such as from anti-fungal medications and the anesthetic etomidate, which may be used when a person undergoes an emergency intubationthe placement of a flexible, plastic tube through the mouth and into the trachea, or windpipe, to assist with breathing
2 |
What causes Adrenal Insufficiency and Addison's Disease ? | A lack of CRH or ACTH causes secondary adrenal insufficiency. The lack of these hormones in the body can be traced to several possible sources.
Stoppage of Corticosteroid Medication
A temporary form of secondary adrenal insufficiency may occur when a person who has been taking a synthetic glucocorticoid hormone, called a corticosteroid, for a long time stops taking the medication. Corticosteroids are often prescribed to treat inflammatory illnesses such as rheumatoid arthritis, asthma, and ulcerative colitis. In this case, the prescription doses often cause higher levels than those normally achieved by the glucocorticoid hormones created by the body. When a person takes corticosteroids for prolonged periods, the adrenal glands produce less of their natural hormones. Once the prescription doses of corticosteroid are stopped, the adrenal glands may be slow to restart their production of the bodys glucocorticoids. To give the adrenal glands time to regain function and prevent adrenal insufficiency, prescription corticosteroid doses should be reduced gradually over a period of weeks or even months. Even with gradual reduction, the adrenal glands might not begin to function normally for some time, so a person who has recently stopped taking prescription corticosteroids should be watched carefully for symptoms of secondary adrenal insufficiency.
Surgical Removal of Pituitary Tumors
Another cause of secondary adrenal insufficiency is surgical removal of the usually noncancerous, ACTH-producing tumors of the pituitary gland that cause Cushings syndrome. Cushings syndrome is a hormonal disorder caused by prolonged exposure of the bodys tissues to high levels of the hormone cortisol. When the tumors are removed, the source of extra ACTH is suddenly gone and a replacement hormone must be taken until the bodys adrenal glands are able to resume their normal production of cortisol. The adrenal glands might not begin to function normally for some time, so a person who has had an ACTH-producing tumor removed and is going off of his or her prescription corticosteroid replacement hormone should be watched carefully for symptoms of adrenal insufficiency.
More information is provided in the NIDDK health topic, Cushings Syndrome.
Changes in the Pituitary Gland
Less commonly, secondary adrenal insufficiency occurs when the pituitary gland either decreases in size or stops producing ACTH. These events can result from
- tumors or an infection in the pituitary - loss of blood flow to the pituitary - radiation for the treatment of pituitary or nearby tumors - surgical removal of parts of the hypothalamus - surgical removal of the pituitary |
How to diagnose Adrenal Insufficiency and Addison's Disease ? | In its early stages, adrenal insufficiency can be difficult to diagnose. A health care provider may suspect it after reviewing a persons medical history and symptoms.
A diagnosis of adrenal insufficiency is confirmed through hormonal blood and urine tests. A health care provider uses these tests first to determine whether cortisol levels are too low and then to establish the cause. Imaging studies of the adrenal and pituitary glands can be useful in helping to establish the cause.
A lab technician performs the following tests in a health care providers office, a commercial facility, or a hospital.
Hormonal Blood and Urine Tests
- ACTH stimulation test. The ACTH stimulation test is the most commonly used test for diagnosing adrenal insufficiency. In this test, the patient is given an intravenous (IV) injection of synthetic ACTH, and samples of blood, urine, or both are taken before and after the injection. The cortisol levels in the blood and urine samples are measured in a lab. The normal response after an ACTH injection is a rise in blood and urine cortisol levels. People with Addisons disease or longstanding secondary adrenal insufficiency have little or no increase in cortisol levels. Both low- and high-dose ACTH stimulation tests may be used depending on the suspected cause of adrenal insufficiency. For example, if secondary adrenal insufficiency is mild or has only recently occurred, the adrenal glands may still respond to ACTH because they have not yet shut down their own production of hormone. Some studies have suggested a low dose1 microgram (mcg)may be more effective in detecting secondary adrenal insufficiency because the low dose is still enough to raise cortisol levels in healthy people, yet not in people with mild or recent secondary adrenal insufficiency. However, recent research has shown that a significant proportion of healthy children and adults can fail the low-dose test, which may lead to unnecessary treatment. Therefore, some health care providers favor using a 250 mcg ACTH test for more accurate results. - CRH stimulation test. When the response to the ACTH test is abnormal, a CRH stimulation test can help determine the cause of adrenal insufficiency. In this test, the patient is given an IV injection of synthetic CRH, and blood is taken before and 30, 60, 90, and 120 minutes after the injection. The cortisol levels in the blood samples are measured in a lab. People with Addisons disease respond by producing high levels of ACTH, yet no cortisol. People with secondary adrenal insufficiency do not produce ACTH or have a delayed response. CRH will not stimulate ACTH secretion if the pituitary is damaged, so no ACTH response points to the pituitary as the cause. A delayed ACTH response points to the hypothalamus as the cause.
Diagnosis during Adrenal Crisis
Although a reliable diagnosis is not possible during adrenal crisis, measurement of blood ACTH and cortisol during the crisisbefore treatment with corticosteroids is givenis often enough to make a preliminary diagnosis. Low blood sodium, low blood glucose, and high blood potassium are also sometimes present at the time of adrenal crisis. Once the crisis is controlled, an ACTH stimulation test can be performed to help make a specific diagnosis. More complex lab tests are sometimes used if the diagnosis remains unclear. |
How to diagnose Adrenal Insufficiency and Addison's Disease ? | After Addisons disease is diagnosed, health care providers may use the following tests to look at the adrenal glands, find out whether the disease is related to TB, or identify antibodies associated with autoimmune Addisons disease.
- Ultrasound of the abdomen. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. A specially trained technician performs the procedure in a health care providers office, an outpatient center, or a hospital, and a radiologista doctor who specializes in medical imaginginterprets the images; a patient does not need anesthesia. The images can show abnormalities in the adrenal glands, such as enlargement or small size, nodules, or signs of calcium deposits, which may indicate bleeding. - Tuberculin skin test. A tuberculin skin test measures how a patients immune system reacts to the bacteria that cause TB. A small needle is used to put some testing material, called tuberculin, under the skin. A nurse or lab technician performs the test in a health care providers office; a patient does not need anesthesia. In 2 to 3 days, the patient returns to the health care provider, who will check to see if the patient had a reaction to the test. The test can show if adrenal insufficiency could be related to TB. To test whether a person has TB infection, which is when TB bacteria live in the body without making the person sick, a special TB blood test is used. To test whether a person has TB disease, which is when TB bacteria are actively attacking a persons lungs and making the person sick, other tests such as a chest x ray and a sample of sputumphlegm that is coughed up from deep in the lungsmay be needed. - Antibody blood tests. A blood test involves drawing blood at a health care providers office or a commercial facility and sending the sample to a lab for analysis. The blood test can detect antibodiesproteins made by the immune system to protect the body from foreign substancesassociated with autoimmune Addisons disease.
After secondary adrenal insufficiency is diagnosed, health care providers may use the following tests to obtain a detailed view of the pituitary gland and assess how it is functioning:
- Computerized tomography (CT) scan. CT scans use a combination of x rays and computer technology to create images. For a CT scan, the patient may be given a solution to drink and an injection of a special dye, called contrast medium. CT scans require the patient to lie on a table that slides into a tunnel-shaped device where the x rays are taken. An x-ray technician performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The patient does not need anesthesia. A CT scan can show size and shape of the pituitary gland to find out if an abnormality is present. - Magnetic resonance imaging (MRI). MRI machines use radio waves and magnets to produce detailed pictures of the bodys internal organs and soft tissues without using x rays. An MRI may include the injection of contrast medium. With most MRI machines, the patient lies on a table that slides into a tunnel-shaped device that may be open ended or closed at one end; some machines are designed to allow the patient to lie in a more open space. A specially trained technician performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The patient does not need anesthesia, though people with a fear of confined spaces may receive light sedation, taken by mouth. MRIs can be used to produce a three-dimensional (3-D) image of the hypothalamus and the pituitary gland to find out if an abnormality is present. - Hormonal blood tests. Hormonal blood tests can assess how the pituitary gland is functioning and its ability to produce other hormones. |
What are the treatments for Adrenal Insufficiency and Addison's Disease ? | Adrenal insufficiency is treated by replacing, or substituting, the hormones that the adrenal glands are not making. The dose of each medication is adjusted to meet the needs of the patient.
Cortisol is replaced with a corticosteroid, such as hydrocortisone, prednisone, or dexamethasone, taken orally one to three times each day, depending on which medication is chosen.
If aldosterone is also deficient, it is replaced with oral doses of a mineralocorticoid hormone, called fludrocortisone acetate (Florinef), taken once or twice daily. People with secondary adrenal insufficiency normally maintain aldosterone production, so they do not require aldosterone replacement therapy.
During adrenal crisis, low blood pressure, low blood glucose, low blood sodium, and high blood levels of potassium can be life threatening. Standard therapy involves immediate IV injections of corticosteroids and large volumes of IV saline solution with dextrose, a type of sugar. This treatment usually brings rapid improvement. When the patient can take liquids and medications by mouth, the amount of corticosteroids is decreased until a dose that maintains normal hormone levels is reached. If aldosterone is deficient, the person will need to regularly take oral doses of fludrocortisone acetate.
Researchers have found that using replacement therapy for DHEA in adolescent girls who have secondary adrenal insufficiency and low levels of DHEA can improve pubic hair development and psychological stress. Further studies are needed before routine supplementation recommendations can be made. |
What are the treatments for Adrenal Insufficiency and Addison's Disease ? | Adrenal crisis is treated with adrenal hormones. People with adrenal crisis need immediate treatment. Any delay can cause death. When people with adrenal crisis are vomiting or unconscious and cannot take their medication, the hormones can be given as an injection.
A person with adrenal insufficiency should carry a corticosteroid injection at all times and make sure that others know how and when to administer the injection, in case the person becomes unconscious.
The dose of corticosteroid needed may vary with a persons age or size. For example, a child younger than 2 years of age can receive 25 milligrams (mg), a child between 2 and 8 years of age can receive 50 mg, and a child older than 8 years should receive the adult dose of 100 mg. |
How to prevent Adrenal Insufficiency and Addison's Disease ? | The following steps can help a person prevent adrenal crisis:
- Ask a health care provider about possibly having a shortage of adrenal hormones, if always feeling tired, weak, or losing weight. - Learn how to increase the dose of corticosteroid for adrenal insufficiency when ill. Ask a health care provider for written instructions for sick days. First discuss the decision to increase the dose with the health care provider when ill. - When very ill, especially if vomiting and not able to take pills, seek emergency medical care immediately. |
What to do for Adrenal Insufficiency and Addison's Disease ? | Some people with Addisons disease who are aldosterone deficient can benefit from following a diet rich in sodium. A health care provider or a dietitian can give specific recommendations on appropriate sodium sources and daily sodium guidelines if necessary.
Corticosteroid treatment is linked to an increased risk of osteoporosisa condition in which the bones become less dense and more likely to fracture. People who take corticosteroids should protect their bone health by consuming enough dietary calcium and vitamin D. A health care provider or a dietitian can give specific recommendations on appropriate daily calcium intake based upon age and suggest the best types of calcium supplements, if necessary. |
What to do for Adrenal Insufficiency and Addison's Disease ? | - Adrenal insufficiency is an endocrine, or hormonal, disorder that occurs when the adrenal glands do not produce enough of certain hormones. - Addisons disease, the common term for primary adrenal insufficiency, occurs when the adrenal glands are damaged and cannot produce enough of the adrenal hormone cortisol. The adrenal hormone aldosterone may also be lacking. - Secondary adrenal insufficiency occurs when the pituitary gland fails to produce enough adrenocorticotropin (ACTH), a hormone that stimulates the adrenal glands to produce cortisol. If ACTH output is too low, cortisol production drops. - The most common symptoms of adrenal insufficiency are chronic fatigue, muscle weakness, loss of appetite, weight loss, and abdominal pain. The slowly progressing symptoms are often ignored until a stressful event, such as surgery, a severe injury, an illness, or pregnancy, causes them to worsen. - If not treated, an adrenal crisis can cause death. - A diagnosis of adrenal insufficiency is confirmed through hormonal blood and urine tests. Imaging studies of the adrenal and pituitary glands can be useful in helping to establish the cause. - Adrenal insufficiency is treated by replacing, or substituting, the hormones that the adrenal glands are not making. - Problems can occur in people with adrenal insufficiency who are undergoing surgery, suffer a severe injury, have an illness, or are pregnant. These conditions place additional stress on the body, and people with adrenal insufficiency may need additional treatment to respond and recover. - People with adrenal insufficiency should always carry identification stating their condition, adrenal insufficiency, in case of an emergency, as well as the supplies necessary to administer an emergency corticosteroid injection. |
What is (are) Urine Blockage in Newborns ? | The urinary tract is the bodys drainage system for removing wastes and extra fluid. The urinary tract includes two kidneys, two ureters, a bladder, and a urethra. The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine. Every day, the kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine, composed of wastes and extra fluid. Children produce less urine than adults. The amount produced depends on their age. The urine flows from the kidneys to the bladder through tubes called ureters. The bladder stores urine until releasing it through urination. When the bladder empties, urine flows out of the body through a tube called the urethra at the bottom of the bladder.
The kidneys and urinary system keep fluids and natural chemicals in the body balanced. While a baby is developing in the mothers womb, called prenatal development, the placentaa temporary organ joining mother and babycontrols much of that balance. The babys kidneys begin to produce urine at about 10 to 12 weeks after conception. However, the mothers placenta continues to do most of the work until the last few weeks of the pregnancy. Wastes and extra water are removed from the babys body through the umbilical cord. The babys urine is released into the amniotic sac and becomes part of the amniotic fluid. This fluid plays a role in the babys lung development. |
What causes Urine Blockage in Newborns ? | Many types of defects in the urinary tract can cause urine blockage:
- Vesicoureteral reflux (VUR). Most children with VUR are born with a ureter that did not grow long enough during development in the womb. The valve formed by the ureter pressing against the bladder wall does not close properly, so urine backs uprefluxesfrom the bladder to the ureter and eventually to the kidney. Severe reflux may prevent a kidney from developing normally and may increase the risk for damage from infections after birth. VUR usually affects only one ureter and kidney, though it can affect both ureters and kidneys. - Ureteropelvic junction (UPJ) obstruction. If urine is blocked where the ureter joins the kidney, only the kidney swells. The ureter remains a normal size. UPJ obstruction usually occurs in only one kidney.
- Bladder outlet obstruction (BOO). BOO describes any blockage in the urethra or at the opening of the bladder.Posterior urethral valves (PUV), the most common form of BOO seen in newborns and during prenatal ultrasound exams, is a birth defect in boys in which an abnormal fold of tissue in the urethra keeps urine from flowing freely out of the bladder. This defect may cause swelling in the entire urinary tract, including the urethra, bladder, ureters, and kidneys. - Ureterocele. If the end of the ureter does not develop normally, it can bulge, creating a ureterocele. The ureterocele may obstruct part of the ureter or the bladder.
Some babies are born with genetic conditions that affect several different systems in the body, including the urinary tract:
- Prune belly syndrome (PBS). PBS is a group of birth defects involving poor development of the abdominal muscles, enlargement of the ureters and bladder, and both testicles remaining inside the body instead of descending into the scrotum. The skin over the abdomen is wrinkled, giving the appearance of a prune. PBS usually occurs in boys, and most children with PBS have hydronephrosisswelling in the kidneyand VUR. - Esophageal atresia (EA). EA is a birth defect in which the esophagusthe muscular tube that carries food and liquids from the mouth to the stomachlacks the opening for food to pass into the stomach. Babies born with EA may also have problems with their spinal columns, digestive systems, hearts, and urinary tracts. - Congenital heart defects. Heart defects range from mild to life threatening. Children born with heart defects also have a higher rate of problems in the urinary tract than children in the general population, suggesting that some types of heart and urinary defects may have a common genetic cause.
Urine blockage can also be caused by spina bifida and other birth defects that affect the spinal cord. These defects may interrupt nerve signals between the bladder, spinal cord, and brain, which are needed for urination, and lead to urinary retentionthe inability to empty the bladder completelyin newborns. Urine that remains in the bladder can reflux into the ureters and kidneys, causing swelling. |
What are the symptoms of Urine Blockage in Newborns ? | Before leaving the hospital, a baby with urine blockage may urinate only small amounts or may not urinate at all. As part of the routine newborn exam, the health care provider may feel an enlarged kidney or find a closed urethra, which may indicate urine blockage. Sometimes urine blockage is not apparent until a child develops symptoms of a urinary tract infection (UTI), including
- fever - irritability - not eating - nausea - diarrhea - vomiting - cloudy, dark, bloody, or foul-smelling urine - urinating often
If these symptoms persist, the child should see a health care provider. A child 2 months of age or younger with a fever should see a health care provider immediately. The health care provider will ask for a urine sample to test for bacteria. |
What are the complications of Urine Blockage in Newborns ? | When a defect in the urinary tract blocks the flow of urine, the urine backs up and causes the ureters to swell, called hydroureter, and hydronephrosis.
Hydronephrosis is the most common problem found during prenatal ultrasound of a baby in the womb. The swelling may be easy to see or barely detectable. The results of hydronephrosis may be mild or severe, yet the long-term outcome for the childs health cannot always be predicted by the severity of swelling. Urine blockage may damage the developing kidneys and reduce their ability to filter. In the most severe cases of urine blockage, where little or no urine leaves the babys bladder, the amount of amniotic fluid is reduced to the point that the babys lung development is threatened.
After birth, urine blockage may raise a childs risk of developing a UTI. Recurring UTIs can lead to more permanent kidney damage. |
How to diagnose Urine Blockage in Newborns ? | Defects of the urinary tract may be diagnosed before or after the baby is born.
Diagnosis before Birth
Tests during pregnancy can help determine if the baby is developing normally in the womb.
- Ultrasound. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. A prenatal ultrasound can show internal organs within the baby. The procedure is performed in a health care providers office, outpatient center, or hospital by a specially trained technician, and the images are interpreted by - a radiologista doctor who specializes in medical imaging, or - an obstetriciana doctor who delivers babies
The images can show enlarged kidneys, ureters, or bladders in babies.
- Amniocentesis. Amniocentesis is a procedure in which amniotic fluid is removed from the mothers womb for testing. The procedure can be performed in the health care providers office, and local anesthetic may be used. The health care provider inserts a thin needle through the abdomen into the uterus to obtain a small amount of amniotic fluid. Cells from the fluid are grown in a lab and then analyzed. The health care provider usually uses ultrasound to find the exact location of the baby. The test can show whether the baby has certain birth defects and how well the babys lungs are developing. - Chorionic villus sampling (CVS). CVS is the removal of a small piece of tissue from the placenta for testing. The procedure can be performed in the health care providers office; anesthesia is not needed. The health care provider uses ultrasound to guide a thin tube or needle through the vagina or abdomen into the placenta. Cells are removed from the placenta and then analyzed. The test can show whether the baby has certain genetic defects.
Most healthy women do not need all of these tests. Ultrasound exams during pregnancy are routine. Amniocentesis and CVS are recommended only when a risk of genetic problems exists because of family history or a problem is detected during an ultrasound. Amniocentesis and CVS carry a slight risk of harming the baby and mother or ending the pregnancy in miscarriage, so the risks should be carefully considered.
Diagnosis after Birth
Different imaging techniques can be used in infants and children to determine the cause of urine blockage.
- Ultrasound. Ultrasound can be used to view the childs urinary tract. For infants, the image is clearer than could be achieved while the baby was in the womb. - Voiding cystourethrogram (VCUG). VCUG is an x-ray image of the bladder and urethra taken while the bladder is full and during urination, also called voiding. The procedure is performed in an outpatient center or hospital by an x-ray technician supervised by a radiologist, who then interprets the images. While anesthesia is not needed, sedation may be used for some children. The bladder and urethra are filled with a special dye, called contrast medium, to make the structures clearly visible on the x-ray images. The x-ray machine captures images of the contrast medium while the bladder is full and when the child urinates. The test can show reflux or blockage of the bladder due to an obstruction, such as PUV. - Radionuclide scan. A radionuclide scan is an imaging technique that detects small amounts of radiation after a person is injected with radioactive chemicals. The dose of the radioactive chemicals is small; therefore, the risk of causing damage to cells is low. Radionuclide scans are performed in an outpatient center or hospital by a specially trained technician, and the images are interpreted by a radiologist. Anesthesia is not needed. Special cameras and computers are used to create images of the radioactive chemicals as they pass through the kidneys. Radioactive chemicals injected into the blood can provide information about kidney function. |
What are the treatments for Urine Blockage in Newborns ? | Treatment for urine blockage depends on the cause and severity of the blockage. Hydronephrosis discovered before the baby is born rarely requires immediate action, especially if it is only on one side. The condition often goes away without any treatment before or after birth. The health care provider should keep track of the condition with frequent ultrasounds.
Surgery
If the urine blockage threatens the life of the unborn baby, a fetal surgeon may recommend surgery to insert a shunt or correct the problem causing the blockage. A shunt is a small tube that can be inserted into the babys bladder to release urine into the amniotic sac. The procedure is similar to amniocentesis, in that a needle is inserted through the mothers abdomen. Ultrasound guides placement of the shunt, which is attached to the end of the needle. Alternatively, an endoscopea small, flexible tube with a lightcan be used to place a shunt or to repair the problem causing the blockage. Fetal surgery carries many risks, so it is performed only in special circumstances, such as when the amniotic fluid is absent and the babys lungs are not developing or when the kidneys are severely damaged.
If the urinary defect does not correct itself after the child is born, and the child continues to have urine blockage, surgery may be needed to remove the obstruction and restore urine flow. The decision to operate depends on the degree of blockage. After surgery, a small tube, called a stent, may be placed in the ureter or urethra to keep it open temporarily while healing occurs.
Antibiotics
Antibiotics are bacteria-fighting medications. A child with possible urine blockage or VUR may be given antibiotics to prevent UTIs from developing until the urinary defect corrects itself or is corrected with surgery.
Intermittent Catheterization
Intermittent catheterization may be used for a child with urinary retention due to a nerve disease. The parent or guardian, and later the child, is taught to drain the bladder by inserting a thin tube, called a catheter, through the urethra to the bladder. Emptying the bladder in this way helps to decrease kidney damage, urine leakage, and UTIs. |

What is (are) Polycystic Kidney Disease ? | Polycystic kidney disease is a genetic disorder that causes numerous cysts to grow in the kidneys. A kidney cyst is an abnormal sac filled with fluid. PKD cysts can greatly enlarge the kidneys while replacing much of their normal structure, resulting in chronic kidney disease (CKD), which causes reduced kidney function over time. CKD may lead to kidney failure, described as end-stage kidney disease or ESRD when treated with a kidney transplant or blood-filtering treatments called dialysis. The two main types of PKD are autosomal dominant PKD and autosomal recessive PKD.
PKD cysts are different from the usually harmless simple cysts that often form in the kidneys later in life. PKD cysts are more numerous and cause complications, such as high blood pressure, cysts in the liver, and problems with blood vessels in the brain and heart. |
What causes Polycystic Kidney Disease ? | A gene mutation, or defect, causes polycystic kidney disease. Genes provide instructions for making proteins in the body. A gene mutation is a permanent change in the deoxyribonucleic acid (DNA) sequence that makes up a gene. In most cases of PKD, a person inherits the gene mutation, meaning a parent passes it on in his or her genes. In the remaining cases, the gene mutation develops spontaneously. In spontaneous cases, neither parent carries a copy of the mutated gene.
Researchers have found three different gene mutations associated with PKD. Two of the genes are associated with autosomal dominant PKD. The third gene is associated with autosomal recessive PKD. Gene mutations that cause PKD affect proteins that play a role in kidney development.
Genetic Disorders Each cell contains thousands of genes that provide the instructions for making proteins for growth and repair of the body. If a gene has a mutation, the protein made by that gene may not function properly, which sometimes creates a genetic disorder. Not all gene mutations cause a disorder. People inherit two copies of most genes; one copy from each parent. A genetic disorder occurs when one or both parents pass a mutated gene to a child at conception. A genetic disorder can also occur through a spontaneous gene mutation, meaning neither parent carries a copy of the mutated gene. Once a spontaneous gene mutation has occurred, a person can pass it to his or her children. Read more about genes and genetic conditions in the U.S. National Library of Medicines (NLMs) Genetics Home Reference. |
How many people are affected by Polycystic Kidney Disease ? | Estimates of PKDs prevalence range from one in 400 to one in 1,000 people.1 According to the United States Renal Data System, PKD accounts for 2.2 percent of new cases of kidney failure each year in the United States. Annually, eight people per 1 million have kidney failure as a result of PKD.2
Polycystic kidney disease exists around the world and in all races. The disorder occurs equally in women and men, although men are more likely to develop kidney failure from PKD. Women with PKD and high blood pressure who have had more than three pregnancies also have an increased chance of developing kidney failure. |
What is (are) Polycystic Kidney Disease ? | Autosomal dominant PKD is the most common form of PKD and the most common inherited disorder of the kidneys.3 The term autosomal dominant means a child can get the disorder by inheriting the gene mutation from only one parent. Each child of a parent with an autosomal dominant mutation has a 50 percent chance of inheriting the mutated gene. About 10 percent of autosomal dominant PKD cases occur spontaneously.4
The following chart shows the chance of inheriting an autosomal dominant gene mutation:
Health care providers identify most cases of autosomal dominant PKD between the ages of 30 and 50.4 For this reason, health care providers often call autosomal dominant PKD adult PKD. However, the onset of kidney damage and how quickly the disorder progresses varies. In some cases, cysts may form earlier in life and grow quickly, causing symptoms in childhood.
The cysts grow out of nephrons, the tiny filtering units inside the kidneys. The cysts eventually separate from the nephrons and continue to enlarge. The kidneys enlarge along with the cystswhich can number in the thousandswhile roughly retaining their kidney shape. In fully developed autosomal dominant PKD, a cyst-filled kidney can weigh as much as 20 to 30 pounds. |
What are the symptoms of Polycystic Kidney Disease ? | In many cases, PKD does not cause signs or symptoms until cysts are half an inch or larger. When present, the most common symptoms are pain in the back and sidesbetween the ribs and hipsand headaches. The pain can be temporary or persistent, mild or severe. Hematuriablood in the urinemay also be a sign of autosomal dominant PKD. |
What are the complications of Polycystic Kidney Disease ? | The complications of autosomal dominant PKD include the following:
- Pain. Cyst infection, other types of urinary tract infections (UTIs), bleeding into cysts, kidney stones, or stretching of the fibrous tissue around the kidney because of cyst growth can cause pain in the area of the kidneys. - High blood pressure. High blood pressure is present in about half of the people with autosomal dominant PKD and normal kidney function between the ages of 20 and 35.4 Almost 100 percent of people with kidney failure and autosomal dominant PKD have high blood pressure.1 High blood pressuregreater than 140/90 mm Hgincreases the likelihood of heart disease and stroke, as well as adding to the damage already done to the kidneys by the cysts. - Kidney failure. Kidney failure means the kidneys no longer work well enough to maintain health. A person with kidney failure may have the following symptoms: - little or no urination - edemaswelling, usually in the legs, feet, or ankles and less often in the hands or face - drowsiness - fatigue, or feeling tired - generalized itching or numbness - dry skin - headaches - weight loss - appetite loss - nausea - vomiting - sleep problems - trouble concentrating - darkened skin - muscle cramps - shortness of breath - chest pain
Untreated kidney failure can lead to coma and death. More than half of people with autosomal dominant PKD progress to kidney failure by age 70.1
- UTIs. Kidney cysts block the flow of urine through the kidneys. Stagnant urine can set the stage for infection. Bacteria enter the urinary tract through the urethra and spread up to the kidneys. Sometimes, the kidney cysts become infected. UTIs may cause scarring in the kidneys. - Kidney stones. About 20 percent of people with autosomal dominant PKD have kidney stones.1 Kidney stones can block the flow of urine and cause pain. - Liver cysts. Liver cysts are the most common nonkidney complication of autosomal dominant PKD.1 Liver cysts generally cause no symptoms. - Pancreatic cysts. PKD can also cause cysts in the pancreas. Pancreatic cysts rarely cause pancreatitisinflammation, or swelling, of the pancreas. - Abnormal heart valves. Abnormal heart valves may occur in up to 25 percent of people with autosomal dominant PKD.1 Insufficient blood flow in the aortathe large artery that carries blood from the heartmay result from the abnormal heart valves. - Diverticula. Diverticula are small pouches, or sacs, that push outward through weak spots in the colon wall. This complication is more common in people with PKD who have kidney failure.1 - Brain aneurysms. An aneurysm is a bulge in the wall of a blood vessel. Aneurysms in the brain might cause headaches that are severe or feel different from other headaches. Brain aneurysms can rupture, or break open, causing bleeding inside the skull. A ruptured aneurysm in the brain is a life-threatening condition and requires immediate medical attention. |
What is (are) Polycystic Kidney Disease ? | Autosomal recessive PKD is a rare genetic disorder that affects the liver as well as the kidneys. The signs of autosomal recessive PKD frequently appear in the earliest months of life, even in the womb, so health care providers often call it infantile PKD. In an autosomal recessive disorder, the child has to inherit the gene mutation from both parents to have an increased likelihood for the disorder. The chance of a child inheriting autosomal recessive mutations from both parents with a gene mutation is 25 percent, or one in four. If only one parent carries the mutated gene, the child will not get the disorder, although the child may inherit the gene mutation. The child is a carrier of the disorder and can pass the gene mutation to the next generation. Genetic testing can show whether a parent or child is a carrier of the mutated gene. Autosomal recessive disorders do not typically appear in every generation of an affected family.
The following chart shows the chance of inheriting an autosomal recessive mutation from parents who both carry the mutated gene:
Read more about how people inherit genetic conditions at the NLMs Genetics Home Reference. |
What are the symptoms of Polycystic Kidney Disease ? | An early sign of autosomal recessive PKD is an enlarged kidney, seen in a fetus or an infant using ultrasound. Kidney function is crucial for early physical development, so children with autosomal recessive PKD and decreased kidney function are usually smaller-than-average size, a condition called growth failure.
Some people with autosomal recessive PKD do not develop signs or symptoms until later in childhood or even adulthood. |
What are the complications of Polycystic Kidney Disease ? | Babies with the most severe cases of autosomal recessive PKD often die hours or days after birth because they cannot breathe well enough to sustain life. Their lungs do not develop as they should during the prenatal period. Pressure from enlarged kidneys also contributes to breathing problems.
Children born with autosomal recessive PKD often develop kidney failure before reaching adulthood.
Liver scarring occurs in all people with autosomal recessive PKD and is usually present at birth. However, liver problems tend to become more of a concern as people with autosomal recessive PKD grow older. Liver scarring can lead to progressive liver dysfunction and other problems.
Additional complications of autosomal recessive PKD include high blood pressure and UTIs. |
How to prevent Polycystic Kidney Disease ? | Scientists have not yet found a way to prevent PKD. However, people with PKD may slow the progression of kidney damage caused by high blood pressure through lifestyle changes, diet, and blood pressure medications. People with PKD should be physically active 30 minutes a day most days of the week. See Eating, Diet, and Nutrition for diet advice on lowering blood pressure and slowing the progression of kidney disease in general. If lifestyle and diet changes do not control a persons blood pressure, a health care provider may prescribe one or more blood pressure medications, including ACE inhibitors or ARBs. |
What to do for Polycystic Kidney Disease ? | A dietitian specializes in helping people who have kidney disease choose the right foods and plan healthy meals. People with any kind of kidney disease, including PKD, should talk with a dietitian about foods that should be added to their diet and foods that might be harmful.
PKD may require diet changes for blood pressure control. Kidney disease in general also calls for certain diet changes.
Following a healthy eating plan can help lower blood pressure. A health care provider may recommend the Dietary Approaches to Stop Hypertension (DASH) eating plan, which focuses on fruits, vegetables, whole grains, and other foods that are heart healthy and lower in sodium, which often comes from salt. The DASH eating plan
- is low in fat and cholesterol - features fat-free or low-fat milk and dairy products, fish, poultry, and nuts - suggests less red meat, sweets, added sugars, and sugar-containing beverages - is rich in nutrients, protein, and fiber
More information about the DASH eating planis available from the National Heart, Lung, and Blood Institute.
As your kidneys become more damaged, you may need to eat foods that are lower in phosphorus and potassium. The health care provider will use lab tests to watch your levels.
Foods high in potassium include
- bananas - oranges - potatoes - tomatoes
Lower-potassium foods include
- apples - peaches - carrots - green beans
Foods higher in phosphorus include
- large portions of meat, fish and dairy foods - bran cereals and oatmeal - beans and nuts - colas
Lower-phosphorus alternatives include
- fresh fruits and vegetables - breads - pasta - rice - corn and rice cereals - light-colored sodas
People with kidney disease and high blood pressure should also limit how much sodium they get to 2,300 mg or less each day.5
People with CKD may need to watch how much protein they eat. Everyone needs protein. However, protein breaks down into wastes the kidneys must remove. Large amounts of protein make the kidneys work harder. High-quality proteins such as meat, fish, and eggs create fewer wastes than other sources of protein. Beans, whole grains, soy products, nuts and nut butters, and dairy products can also be good sources of protein. Most people eat more protein than they need. Eating high-quality protein and smaller portions of protein can help protect the kidneys.

What to do for Polycystic Kidney Disease ? | - Polycystic kidney disease (PKD) is a genetic disorder that causes numerous cysts to grow in the kidneys. - A gene mutation, or defect, causes polycystic kidney disease. - Autosomal dominant PKD is the most common form of PKD and the most common inherited disorder of the kidneys. - Health care providers identify most cases of autosomal dominant PKD between the ages of 30 and 50. - The most common symptoms of PKD are pain in the back and sidesbetween the ribs and hipsand headaches. The pain can be temporary or persistent, mild or severe. Hematuriablood in the urinemay also be a sign of autosomal dominant PKD. - The complications of autosomal dominant PKD include the following: - pain - high blood pressure - kidney failure - urinary tract infections (UTIs) - kidney stones - liver cysts - pancreatic cysts - abnormal heart valves - diverticula - brain aneurysms - A health care provider diagnoses autosomal dominant PKD using imaging tests and genetic testing. - A radiologista doctor who specializes in medical imagingwill interpret the images produced by the following imaging tests: - ultrasound - computerized tomography scans - magnetic resonance imaging - Genetic testing can show whether a persons cells carry a gene mutation that causes autosomal dominant PKD. A health care provider may also use genetic testing results to determine whether someone with a family history of PKD is likely to develop the disorder in the future. Prenatal testing can diagnose autosomal recessive PKD in unborn children. - Although a cure for autosomal dominant PKD is not currently available, treatment can ease symptoms and prolong life. - Autosomal recessive PKD is a rare genetic disorder that affects the liver as well as the kidneys. - The complications of autosomal recessive PKD include the following: - death due to breathing problems - kidney failure - liver scarring - high blood pressure - UTIs - A health care provider diagnoses autosomal recessive PKD with ultrasound imaging, even in a fetus or newborn. - Treatments for autosomal recessive PKD focus on the symptoms and complications. - Scientists have not yet found a way to prevent PKD. However, people with PKD may slow the progression of kidney damage caused by high blood pressure through lifestyle changes, diet, and blood pressure medications. - People with any kind of kidney disease, including PKD, should talk with a dietitian about foods they should add to their diet and foods that might be harmful. |
What is (are) Prevent diabetes problems: Keep your kidneys healthy ? | Your kidneys are two bean-shaped organs, each about the size of a fist. They are located just below your rib cage, one on each side of your spine. Every day, your two kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine. Urine flows from your kidneys to your bladder through tubes called ureters. Your bladder stores urine until releasing it through urination. |
What is (are) Prevent diabetes problems: Keep your kidneys healthy ? | Blood pressure is the force of blood flow inside your blood vessels. Blood pressure is written with two numbers separated by a slash. For example, a blood pressure result of 130/80 is said as 130 over 80. The first number is the pressure in your blood vessels as your heart beats and pushes blood through your blood vessels. The second number is the pressure as your blood vessels relax between heartbeats.
High blood pressure forces your heart to work harder to pump blood. High blood pressure can strain your heart, damage your blood vessels, and increase your risk of heart attack, stroke, eye problems, and kidney problems. |
What are the symptoms of Prevent diabetes problems: Keep your kidneys healthy ? | In the early stages, diabetic kidney disease does not have any symptoms. Kidney disease happens so slowly that you may not feel sick at all for many years. You may not feel sick even when your kidneys do only half the job of healthy kidneys. Only your doctor can tell if you have kidney disease by checking the protein, or albumin, level in your urine at least once a year.
The first symptom of diabetic kidney disease is often swelling in parts of your body, such as your hands, face, feet, or ankles. Also, large amounts of protein in your urine may cause urine to look foamy. Once your kidney function starts to decrease, other symptoms may include
- increased or decreased urination - feeling drowsy or tired - feeling itchy or numb - dry skin - headaches - weight loss - not feeling hungry - feeling sick to your stomach - vomiting - sleep problems - trouble staying focused - darkened skin - muscle cramps |
What to do for Prevent diabetes problems: Keep your kidneys healthy ? | Your dietitian or doctor may suggest a special eating plan for you. You may have to avoid a diet high in protein, fat, sodium, and potassium.
- Cut back on protein, especially animal products such as meat. Damaged kidneys may fail to remove protein waste products from your blood. Diets high in protein make your kidneys work harder and fail sooner. - Avoid a high-fat diet. High-fat diets are high in cholesterol. Cholesterol is a type of fat found in your bodys cells, blood, and many foods. Your body needs some cholesterol to work the right way. For example, your body uses cholesterol to make certain essential hormones and maintain nerve function. However, your body makes all the cholesterol it needs. If you often eat foods that are high in cholesterol, or if high cholesterol runs in your family, extra cholesterol in your blood can build up over time in the walls of your blood vessels and arteries. High blood cholesterol can lead to heart disease and stroke, some of the biggest health problems for people with diabetes. - Avoid high-sodium foods. Sodium is a mineral found in salt and other foods. High levels of sodium may raise your blood pressure. Some high-sodium foods include canned food, frozen dinners, and hot dogs. The amount of sodium is listed on the food label, so you can see which foods have the highest levels. Try to limit your sodium to less than a teaspoon a day, or about 2,300 milligrams (mg) a day. If you have high blood pressure or are African American, middle-aged, or older, aim for no more than 1,500 mg of sodium per day. Ask your doctor or your dietitian about how much sodium you can have. - Ask your doctor about the amount of potassium you need. Potassium is a mineral that helps your heartbeat stay regular and muscles work right. Healthy kidneys keep the right amount of potassium in your body. However, if you have severe kidney damage, high levels of potassium may cause an abnormal heart rhythm or even make your heart stop, called cardiac arrest. Some high-potassium foods include apricots, bananas, oranges, and potatoes.

What is (are) Prevent diabetes problems: Keep your kidneys healthy ? | Kidney failure, also called end-stage kidney disease or ESRD, means your kidneys no longer work well enough to do their job. You will need treatment to replace the work your kidneys have stopped doing. |
What causes Nerve Disease and Bladder Control ? | Nerves that work poorly can lead to three different kinds of bladder control problems.
Overactive bladder. Damaged nerves may send signals to the bladder at the wrong time, causing its muscles to squeeze without warning. The symptoms of overactive bladder include
- urinary frequencydefined as urination eight or more times a day or two or more times at night - urinary urgencythe sudden, strong need to urinate immediately - urge incontinenceleakage of urine that follows a sudden, strong urge to urinate
Poor control of sphincter muscles. Sphincter muscles surround the urethra and keep it closed to hold urine in the bladder. If the nerves to the sphincter muscles are damaged, the muscles may become loose and allow leakage or stay tight when you are trying to release urine.
Urine retention. For some people, nerve damage means their bladder muscles do not get the message that it is time to release urine or are too weak to completely empty the bladder. If the bladder becomes too full, urine may back up and the increasing pressure may damage the kidneys. Or urine that stays too long may lead to an infection in the kidneys or bladder. Urine retention may also lead to overflow incontinence. |
What causes Nerve Disease and Bladder Control ? | Many events or conditions can damage nerves and nerve pathways. Some of the most common causes are
- vaginal childbirth - infections of the brain or spinal cord - diabetes - stroke - accidents that injure the brain or spinal cord - multiple sclerosis - heavy metal poisoning
In addition, some children are born with nerve problems that can keep the bladder from releasing urine, leading to urinary infections or kidney damage. |
What are the treatments for Nerve Disease and Bladder Control ? | The treatment for a bladder control problem depends on the cause of the nerve damage and the type of voiding dysfunction that results.
In the case of overactive bladder, your doctor may suggest a number of strategies, including bladder training, electrical stimulation, drug therapy, and, in severe cases where all other treatments have failed, surgery.
Bladder training. Your doctor may ask you to keep a bladder diary-a record of your fluid intake, trips to the bathroom, and episodes of urine leakage. This record may indicate a pattern and suggest ways to avoid accidents by making a point of using the bathroom at certain times of the day-a practice called timed voiding. As you gain control, you can extend the time between trips to the bathroom. Bladder training also includes Kegel exercises to strengthen the muscles that hold in urine.
Electrical stimulation. Mild electrical pulses can be used to stimulate the nerves that control the bladder and sphincter muscles. Depending on which nerves the doctor plans to treat, these pulses can be given through the vagina or anus, or by using patches on the skin. Another method is a minor surgical procedure to place the electric wire near the tailbone. This procedure involves two steps. First, the wire is placed under the skin and connected to a temporary stimulator, which you carry with you for several days. If your condition improves during this trial period, then the wire is placed next to the tailbone and attached to a permanent stimulator under your skin. The Food and Drug Administration (FDA) has approved this device, marketed as the InterStim system, to treat urge incontinence, urgency-frequency syndrome, and urinary retention in patients for whom other treatments have not worked.
Drug therapy. Different drugs can affect the nerves and muscles of the urinary tract in different ways.
- Drugs that relax bladder muscles and prevent bladder spasms include oxybutynin chloride (Ditropan), tolterodine (Detrol), hyoscyamine (Levsin), and propantheline bromide (Pro-Banthine), which belong to the class of drugs called anticholinergics. Their most common side effect is dry mouth, although large doses may cause blurred vision, constipation, a faster heartbeat, and flushing. A new patch delivery system for oxybutynin (Oxytrol) may decrease side effects. Ditropan XL and Detrol LA are timed-release formulations that deliver a low level of the drug continuously in the body. These drugs have the advantage of once-a-day administration. In 2004, the FDA approved trospium chloride (Sanctura), darifenacin (Enablex), and solifenacin succinate (VESIcare) for the treatment of overactive bladder. - Drugs for depression that also relax bladder muscles include imipramine hydrochloride (Tofranil), a tricyclic antidepressant. Side effects may include fatigue, dry mouth, dizziness, blurred vision, nausea, and insomnia.
Additional drugs are being evaluated for the treatment of overactive bladder and may soon receive FDA approval.
Surgery. In extreme cases, when incontinence is severe and other treatments have failed, surgery may be considered. The bladder may be made larger through an operation known as augmentation cystoplasty, in which a part of the diseased bladder is replaced with a section taken from the patient's bowel. This operation may improve the ability to store urine but may make the bladder more difficult to empty, making regular catheterization necessary. Additional risks of surgery include the bladder breaking open and leaking urine into the body, bladder stones, mucus in the bladder, and infection. |
What are the treatments for Nerve Disease and Bladder Control ? | The job of the sphincter muscles is to hold urine in the bladder by squeezing the urethra shut. If the urethral sphincter fails to stay closed, urine may leak out of the bladder. When nerve signals are coordinated properly, the sphincter muscles relax to allow urine to pass through the urethra as the bladder contracts to push out urine. If the signals are not coordinated, the bladder and the sphincter may contract at the same time, so urine cannot pass easily.
Drug therapy for an uncoordinated bladder and urethra. Scientists have not yet found a drug that works selectively on the urethral sphincter muscles, but drugs used to reduce muscle spasms or tremors are sometimes used to help the sphincter relax. Baclofen (Lioresal) is prescribed for muscle spasms or cramping in patients with multiple sclerosis and spinal injuries. Diazepam (Valium) can be taken as a muscle relaxant or to reduce anxiety. Drugs called alpha-adrenergic blockers can also be used to relax the sphincter. Examples of these drugs are alfuzosin (UroXatral), tamsulosin (Flomax), terazosin (Hytrin), and doxazosin (Cardura). The main side effects are low blood pressure, dizziness, fainting, and nasal congestion. All of these drugs have been used to relax the urethral sphincter in people whose sphincter does not relax well on its own.
Botox injection. Botulinum toxin type A (Botox) is best known as a cosmetic treatment for facial wrinkles. Doctors have also found that botulinum toxin is useful in blocking spasms like eye ticks or relaxing muscles in patients with multiple sclerosis. Urologists have found that injecting botulinum toxin into the tissue surrounding the sphincter can help it to relax. Although the FDA has approved botulinum toxin only for facial cosmetic purposes, researchers are studying the safety and effectiveness of botulinum toxin injection into the sphincter for possible FDA approval in the future. |
