Question:
How to prevent Heart Palpitations ?

Answer:
You can take steps to prevent palpitations. Try to avoid things that trigger them. For example:
                
Reduce anxiety and stress. Anxiety and stress (including panic attacks) are a common cause of harmless palpitations. Relaxation exercises, yoga or tai chi, biofeedback or guided imagery, or aromatherapy may help you relax.
                
Avoid or limit stimulants, such as caffeine, nicotine, or alcohol.
                
Avoid illegal drugs, such as cocaine and amphetamines.
                
Avoid medicines that act as stimulants, such as cough and cold medicines and some herbal and nutritional supplements.
                
Also, work with your doctor to treat medical conditions that can cause palpitations.
Question:
What is (are) Thalassemias ?

Answer:
Thalassemias (thal-a-SE-me-ahs) are inherited blood disorders. "Inherited" means that the disorder is passed from parents to children through genes.
                
Thalassemias cause the body to make fewer healthy red blood cells and less hemoglobin (HEE-muh-glow-bin) than normal. Hemoglobin is an iron-rich protein in red blood cells. It carries oxygen to all parts of the body. Hemoglobin also carries carbon dioxide (a waste gas) from the body to the lungs, where it's exhaled.
                
People who have thalassemias can have mild or severe anemia (uh-NEE-me-uh). Anemia is caused by a lower than normal number of red blood cells or not enough hemoglobin in the red blood cells.
                
Overview
                
Normal hemoglobin, also called hemoglobin A, has four protein chainstwo alpha globin and two beta globin. The two major types of thalassemia, alpha and beta, are named after defects in these protein chains.
                
Four genes (two from each parent) are needed to make enough alpha globin protein chains. Alpha thalassemia trait occurs if one or two of the four genes are missing. If more than two genes are missing, moderate to severe anemia occurs.
                
The most severe form of alpha thalassemia is called alpha thalassemia major or hydrops fetalis. Babies who have this disorder usually die before or shortly after birth.
                
Two genes (one from each parent) are needed to make enough beta globin protein chains. Beta thalassemia occurs if one or both genes are altered.
                
The severity of beta thalassemia depends on how much one or both genes are affected. If both genes are affected, the result is moderate to severe anemia. The severe form of beta thalassemia is known as thalassemia major or Cooley's anemia.
                
Thalassemias affect males and females. The disorders occur most often among people of Italian, Greek, Middle Eastern, Southern Asian, and African descent. Severe forms usually are diagnosed in early childhood and are lifelong conditions.
                
Doctors diagnose thalassemias using blood tests. The disorders are treated with blood transfusions, medicines, and other procedures.
                
Outlook
                
Treatments for thalassemias have improved over the years. People who have moderate or severe thalassemias are now living longer and have better quality of life.
                
However, complications from thalassemias and their treatments are frequent. People who have moderate or severe thalassemias must closely follow their treatment plans. They need to take care of themselves to remain as healthy as possible.
Question:
What causes Thalassemias ?

Answer:
Your body makes three types of blood cells: red blood cells, white blood cells, and platelets (PLATE-lets). Red blood cells contain hemoglobin, an iron-rich protein that carries oxygen from your lungs to all parts of your body. Hemoglobin also carries carbon dioxide (a waste gas) from your body to your lungs, where it's exhaled.
                
Hemoglobin has two kinds of protein chains: alpha globin and beta globin. If your body doesn't make enough of these protein chains or they're abnormal, red blood cells won't form correctly or carry enough oxygen. Your body won't work well if your red blood cells don't make enough healthy hemoglobin.
                
Genes control how the body makes hemoglobin protein chains. When these genes are missing or altered, thalassemias occur.
                
Thalassemias are inherited disordersthat is, they're passed from parents to children through genes. People who inherit faulty hemoglobin genes from one parent but normal genes from the other are called carriers. Carriers often have no signs of illness other than mild anemia. However, they can pass the faulty genes on to their children.
                
People who have moderate to severe forms of thalassemia have inherited faulty genes from both parents.
                
Alpha Thalassemias
                
You need four genes (two from each parent) to make enough alpha globin protein chains. If one or more of the genes is missing, you'll have alpha thalassemia trait or disease. This means that your body doesn't make enough alpha globin protein.
                
If you're only missing one gene, you're a "silent" carrier. This means you won't have any signs of illness.
                
If you're missing two genes, you have alpha thalassemia trait (also called alpha thalassemia minor). You may have mild anemia.
                
If you're missing three genes, you likely have hemoglobin H disease (which a blood test can detect). This form of thalassemia causes moderate to severe anemia.
                
Very rarely, a baby is missing all four genes. This condition is called alpha thalassemia major or hydrops fetalis. Babies who have hydrops fetalis usually die before or shortly after birth.
                
Example of an Inheritance Pattern for Alpha Thalassemia
                

                
Beta Thalassemias
                
You need two genes (one from each parent) to make enough beta globin protein chains. If one or both of these genes are altered, you'll have beta thalassemia. This means that your body wont make enough beta globin protein.
                
If you have one altered gene, you're a carrier. This condition is called beta thalassemia trait or beta thalassemia minor. It causes mild anemia.
                
If both genes are altered, you'll have beta thalassemia intermedia or beta thalassemia major (also called Cooley's anemia). The intermedia form of the disorder causes moderate anemia. The major form causes severe anemia.

Question:
Who is at risk for Thalassemias? ?

Answer:
Family history and ancestry are the two risk factors for thalassemias.
                
Family History
                
Thalassemias are inheritedthat is, the genes for the disorders are passed from parents to their children. If your parents have missing or altered hemoglobin-making genes, you may have thalassemia.
                
Ancestry
                
Thalassemias occur most often among people of Italian, Greek, Middle Eastern, Southern Asian, and African descent.
Question:
How to diagnose Thalassemias ?

Answer:
Doctors diagnose thalassemias using blood tests, including a complete blood count (CBC) and special hemoglobin tests.
                
A CBC measures the amount of hemoglobin and the different kinds of blood cells, such as red blood cells, in a sample of blood. People who have thalassemias have fewer healthy red blood cells and less hemoglobin than normal in their blood. People who have alpha or beta thalassemia trait may have red blood cells that are smaller than normal.
                
Hemoglobin tests measure the types of hemoglobin in a blood sample. People who have thalassemias have problems with the alpha or beta globin protein chains of hemoglobin.
                
Moderate and severe thalassemias usually are diagnosed in early childhood. This is because signs and symptoms, including severe anemia, often occur within the first 2years of life.
                
People who have milder forms of thalassemia might be diagnosed after a routine blood test shows they have anemia. Doctors might suspect thalassemia if a person has anemia and is a member of an ethnic group that's at increased risk for thalassemias. (For more information, go to "Who Is at Risk for Thalassemias?")
                
Doctors also test the amount of iron in the blood to find out whether the anemia is due to iron deficiency or thalassemia. Iron-deficiency anemia occurs if the body doesn't have enough iron to make hemoglobin. The anemia in thalassemia occurs because of a problem with either the alpha globin or beta globin chains of hemoglobin, not because of a lack of iron.
                
Because thalassemias are passed from parents to children through genes, family genetic studies also can help diagnose the disorder. These studies involve taking a family medical history and doing blood tests on family members. The tests will show whether any family members have missing or altered hemoglobin genes.
                
If you know of family members who have thalassemias and you're thinking of having children, consider talking with your doctor and a genetic counselor. They can help determine your risk for passing the disorder to your children.
                
If you're expecting a baby and you and your partner are thalassemia carriers, you may want to consider prenatal testing.
                
Prenatal testing involves taking a sample of amniotic fluid or tissue from the placenta. (Amniotic fluid is the fluid in the sac surrounding a growing embryo. The placenta is the organ that attaches the umbilical cord to the mother's womb.) Tests done on the fluid or tissue can show whether your baby has thalassemia and how severe it might be.
Question:
How to prevent Thalassemias ?

Answer:
You cant prevent thalassemias because theyre inherited (passed from parents to children through genes). However, prenatal tests can detect these blood disorders before birth.
                
Family genetic studies may help find out whether people have missing or altered hemoglobin genes that cause thalassemias. (For more information, go to "How Are Thalassemias Diagnosed?")
                
If you know of family members who have thalassemias and you're thinking of having children, consider talking with your doctor and a genetic counselor. They can help determine your risk for passing the disorder to your children.
Question:
What is (are) Hemochromatosis ?

Answer:
Hemochromatosis (HE-mo-kro-ma-TO-sis) is a disease in which too much iron builds up in your body (iron overload). Iron is a mineral found in many foods.
                
Too much iron is toxic to your body. It can poison your organs and cause organ failure. In hemochromatosis, iron can build up in most of your body's organs, but especially in the liver, heart, and pancreas.
                
Too much iron in the liver can cause an enlarged liver, liver failure, liver cancer, or cirrhosis (sir-RO-sis). Cirrhosis is scarring of the liver, which causes the organ to not work well.
                
Too much iron in the heart can cause irregular heartbeats called arrhythmias (ah-RITH-me-ahs) and heart failure. Too much iron in the pancreas can lead to diabetes.
                
If hemochromatosis isn't treated, it may even cause death.
                
Overview
                
The two types of hemochromatosis are primary and secondary. Primary hemochromatosis is caused by a defect in the genes that control how much iron you absorb from food. Secondary hemochromatosis usually is the result of another disease or condition that causes iron overload.
                
Most people who have primary hemochromatosis inherit it from their parents. If you inherit two hemochromatosis genesone from each parentyou're at risk for iron overload and signs and symptoms of the disease. The two faulty genes cause your body to absorb more iron than usual from the foods you eat.
                
Hemochromatosis is one of the most common genetic disorders in the United States. However, not everyone who has hemochromatosis has signs or symptoms of the disease.
                
Estimates of how many people develop signs and symptoms vary greatly. Some estimates suggest that as many as half of all people who have the disease don't have signs or symptoms.
                
The severity of hemochromatosis also varies. Some people don't have complications, even with high levels of iron in their bodies. Others have severe complications or die from the disease.
                
Certain factors can affect the severity of the disease. For example, a high intake of vitamin C can make hemochromatosis worse. This is because vitamin C helps your body absorb iron from food.
                
Alcohol use can worsen liver damage and cirrhosis caused by hemochromatosis. Conditions such as hepatitis also can further damage or weaken the liver.
                
Outlook
                
The outlook for people who have hemochromatosis largely depends on how much organ damage they have at the time of diagnosis. Early diagnosis and treatment of the disease are important.
                
Treatment may help prevent, delay, or sometimes reverse complications of the disease. Treatment also may lead to better quality of life.
                
For people who are diagnosed and treated early, a normal lifespan is possible. If left untreated, hemochromatosis can lead to severe organ damage and even death.
Question:
What causes Hemochromatosis ?

Answer:
The two types of hemochromatosis are primary and secondary. Each type has a different cause.
                
Primary Hemochromatosis
                
Primary hemochromatosis is caused by a defect in the genes that control how much iron you absorb from food. This form of the disease sometimes is called hereditary or classical hemochromatosis. Primary hemochromatosis is more common than the secondary form of the disease.
                
The genes usually involved in primary hemochromatosis are called HFE genes. Faulty HFE genes cause the body to absorb too much iron. If you inherit two copies of the faulty HFE gene (one from each parent), you're at risk for iron overload and signs and symptoms of hemochromatosis.
                
If you inherit one faulty HFE gene and one normal HFE gene, you're a hemochromatosis "carrier." Carriers usually don't develop the disease. However, they can pass the faulty gene on to their children. Estimates suggest that about 1 in 10 people in the United States are hemochromatosis carriers.
                
If two parents are carriers of the faulty HFE gene, then each of their children has a 1 in 4 chance of inheriting two faulty HFE genes.
                
Although less common, other faulty genes also can cause hemochromatosis. Researchers continue to study what changes to normal genes may cause the disease.
                
Secondary Hemochromatosis
                
Secondary hemochromatosis usually is the result of another disease or condition that causes iron overload. Examples of such diseases and conditions include:
                
Certain types of anemia, such as thalassemias and sideroblastic anemia
                
Atransferrinemia and aceruloplasminemiaboth are rare, inherited diseases
                
Chronic liver diseases, such as chronic hepatitis C infection, alcoholic liver disease, or nonalcoholic steatohepatitis
                
Other factors also can cause secondary hemochromatosis, including:
                
Blood transfusions
                
Oral iron pills or iron injections, with or without very high vitamin C intake (vitamin C helps your body absorb iron)
                
Long-term kidney dialysis
Question:
Who is at risk for Hemochromatosis? ?

Answer:
Hemochromatosis is one of the most common genetic diseases in the United States. It's most common in Caucasians of Northern European descent. The disease is less common in African Americans, Hispanics, Asians, and American Indians.
                
Primary hemochromatosis is more common in men than in women. Also, older people are more likely to develop the disease than younger people. In fact, signs and symptoms usually don't occur in men until they're 40 to 60 years old.
                
In women, signs and symptoms usually don't occur until after the age of 50 (after menopause). Young children rarely develop hemochromatosis.
                
Inheriting two faulty HFE genes (one from each parent) is the major risk factor for hemochromatosis. However, many people who have two copies of the faulty gene don't develop signs or symptoms of the disease.
                
Alcoholism is another risk factor for hemochromatosis. A family history of certain diseases and conditions also puts you at higher risk for hemochromatosis. Examples of such diseases and conditions include heart attack, liver disease, diabetes, arthritis, and erectile dysfunction (impotence).
Question:
What are the symptoms of Hemochromatosis ?

Answer:
Hemochromatosis can affect many parts of the body and cause various signs and symptoms. Many of the signs and symptoms are similar to those of other diseases.
                
Signs and symptoms of hemochromatosis usually don't occur until middle age. Women are more likely to have general symptoms first, such as fatigue (tiredness). In men, complications such as diabetes or cirrhosis (scarring of the liver) often are the first signs of the disease.
                
Signs and symptoms also vary based on the severity of the disease. Common signs and symptoms of hemochromatosis include joint pain, fatigue, general weakness, weight loss, and stomach pain.
                
Not everyone who has hemochromatosis has signs or symptoms of the disease. Estimates of how many people develop signs and symptoms vary greatly. Some estimates suggest that as many as half of all people who have the disease don't have signs or symptoms.
                
Hemochromatosis Complications
                
If hemochromatosis isn't found and treated early, iron builds up in your body and can lead to:
                
Liver disease, including an enlarged liver, liver failure, liver cancer, or cirrhosis (scarring of the liver)
                
Heart problems, including arrhythmias (irregular heartbeats) and heart failure
                
Diabetes, especially in people who have a family history of diabetes
                
Joint damage and pain, including arthritis
                
Reproductive organ failure, such as erectile dysfunction (impotence), shrinkage of the testicles, and loss of sex drive in men, and absence of the menstrual cycle and early menopause in women
                
Changes in skin color that make the skin look gray or bronze
                
Underactive pituitary and thyroid glands
                
Damage to the adrenal glands
Question:
What are the treatments for Hemochromatosis ?

Answer:
Treatments for hemochromatosis include therapeutic phlebotomy (fleh-BOT-o-me), iron chelation (ke-LAY-shun) therapy, dietary changes, and treatment for complications.
                
The goals of treating hemochromatosis include:
                
Reducing the amount of iron in your body to normal levels
                
Preventing or delaying organ damage from iron overload
                
Treating complications of the disease
                
Maintaining a normal amount of iron in your body for the rest of your life
                
Therapeutic Phlebotomy
                
Therapeutic phlebotomy is a procedure that removes blood (and iron) from your body. A needle is inserted into a vein, and your blood flows through an airtight tube into a sterile container or bag.
                
The process is similar to donating blood; it can be done at blood donation centers, hospital donation centers, or a doctor's office.
                
In the first stage of treatment, about 1 pint of blood is removed once or twice a week. After your iron levels return to normal, you may continue phlebotomy treatments. However, you may need them less oftentypically every 24 months.
                
As long as treatment continues, which often is for the rest of your life, you'll need frequent blood tests to check your iron levels.
                
Iron Chelation Therapy
                
Iron chelation therapy uses medicine to remove excess iron from your body. This treatment is a good option for people who can't have routine blood removal.
                
The medicine used in iron chelation therapy is either injected or taken orally (by mouth). Injected iron chelation therapy is done at a doctor's office. Oral iron chelation therapy can be done at home.
                
Dietary Changes
                
Your doctor may suggest that you change your diet if you have hemochromatosis. You may be advised to:
                
Avoid taking iron, including iron pills, iron injections, or multivitamins that contain iron.
                
Limit your intake of vitamin C. Vitamin C helps your body absorb iron from food. Talk with your doctor about how much vitamin C is safe for you.
                
Avoid uncooked fish and shellfish. Some fish and shellfish contain bacteria that can cause infections in people who have chronic diseases, such as hemochromatosis.
                
Limit alcohol intake. Drinking alcohol increases the risk of liver disease. It also can make existing liver disease worse.
                
Treatment for Complications
                
Your doctor may prescribe other treatments as needed for complications such as liver disease, heart problems, or diabetes.
Question:
How to prevent Hemochromatosis ?

Answer:
You can't prevent primary, or inherited, hemochromatosis. However, not everyone who inherits hemochromatosis genes develops symptoms or complications of the disease. In those who do, treatments can keep the disease from getting worse.
                
Treatments include therapeutic phlebotomy, iron chelation therapy, dietary changes, and other treatments. For more information, go to "How Is Hemochromatosis Treated?"
                
People who have hemochromatosis (or a family history of it) and are planning to have children may want to consider genetic testing and counseling. Testing will help show whether one or both parents have faulty HFE genes. A genetic counselor also can help figure out the likelihood of the parents passing the faulty genes on to their children.
