user: How to prevent Iron-Deficiency Anemia ?

assistant: Eating a well-balanced diet that includes iron-rich foods may help you prevent iron-deficiency anemia.
                
Taking iron supplements also may lower your risk for the condition if you're not able to get enough iron from food. Large amounts of iron can be harmful, so take iron supplements only as your doctor prescribes.
                
For more information about diet and supplements, go to "How Is Iron-Deficiency Anemia Treated?"
                
Infants and young children and women are the two groups at highest risk for iron-deficiency anemia. Special measures can help prevent the condition in these groups.
                
Infants and Young Children
                
A baby's diet can affect his or her risk for iron-deficiency anemia. For example, cow's milk is low in iron. For this and other reasons, cow's milk isn't recommended for babies in their first year. After the first year, you may need to limit the amount of cow's milk your baby drinks.
                
Also, babies need more iron as they grow and begin to eat solid foods. Talk with your child's doctor about a healthy diet and food choices that will help your child get enough iron.
                
Your child's doctor may recommend iron drops. However, giving a child too much iron can be harmful. Follow the doctor's instructions and keep iron supplements and vitamins away from children. Asking for child-proof packages for supplements can help prevent overdosing in children.
                
Because recent research supports concerns that iron deficiency during infancy and childhood can have long-lasting, negative effects on brain health, the American Academy of Pediatrics recommends testing all infants for anemia at 1 year of age.
                
Women and Girls
                
Women of childbearing age may be tested for iron-deficiency anemia, especially if they have:
                
A history of iron-deficiency anemia
                
Heavy blood loss during their monthly periods
                
Other risk factors for iron-deficiency anemia
                
The Centers for Disease Control and Prevention (CDC) has developed guidelines for who should be screened for iron deficiency, and how often:
                
Girls aged 12 to 18 and women of childbearing age who are not pregnant: Every 5 to 10 years.
                
Women who have risk factors for iron deficiency: Once a year.
                
Pregnant women: At the first prenatal visit.
                
For pregnant women, medical care during pregnancy usually includes screening for anemia. Also, your doctor may prescribe iron supplements or advise you to eat more iron-rich foods.This not only will help you avoid iron-deficiency anemia, but also may lower your risk of having a low-birth-weight baby.
user: What causes Atrial Fibrillation ?

assistant: Atrial fibrillation (AF) occurs if the heart's electrical signals don't travel through the heart in a normal way. Instead, they become very rapid and disorganized.
                
Damage to the heart's electrical system causes AF. The damage most often is the result of other conditions that affect the health of the heart, such as high blood pressure and coronary heart disease.
                
The risk of AF increases as you age. Inflammation also is thought to play a role in causing AF.
                
Sometimes, the cause of AF is unknown.
user: Who is at risk for Atrial Fibrillation? ?

assistant: Atrial fibrillation (AF) affects millions of people, and the number is rising. Men are more likely than women to have the condition. In the United States, AF is more common among Whites than African Americans or Hispanic Americans.
                
The risk of AF increases as you age. This is mostly because your risk for heart disease and other conditions that can cause AF also increases as you age. However, about half of the people who have AF are younger than 75.
                
AF is uncommon in children.
                
Major Risk Factors
                
AF is more common in people who have:
                
High blood pressure
                
Coronary heart disease (CHD)
                
Heart failure
                
Rheumatic (ru-MAT-ik) heart disease
                
Structural heart defects, such as mitral valve prolapse
                
Pericarditis (PER-i-kar-DI-tis; a condition in which the membrane, or sac, around your heart is inflamed)
                
Congenital heart defects
                
Sick sinus syndrome (a condition in which the heart's electrical signals don't fire properly and the heart rate slows down; sometimes the heart will switch back and forth between a slow rate and a fast rate)
                
AF also is more common in people who are having heart attacks or who have just had surgery.
                
Other Risk Factors
                
Other conditions that raise your risk for AF include hyperthyroidism (too much thyroid hormone), obesity, diabetes, and lung disease.
                
Certain factors also can raise your risk for AF. For example, drinking large amounts of alcohol, especially binge drinking, raises your risk. Even modest amounts of alcohol can trigger AF in some people. Caffeine or psychological stress also may trigger AF in some people.
                
Some data suggest that people who have sleep apnea are at greater risk for AF. Sleep apnea is a common disorder that causes one or more pauses in breathing or shallow breaths while you sleep.
                
Metabolic syndrome also raises your risk for AF. Metabolic syndrome is the name for a group of risk factors that raises your risk for CHD and other health problems, such as diabetes and stroke.
                
Research suggests that people who receive high-dose steroid therapy are at increased risk for AF. This therapy is used for asthma and some inflammatory conditions. It may act as a trigger in people who have other AF risk factors.
                
Genetic factors also may play a role in causing AF. However, their role isn't fully known.
user: What are the symptoms of Atrial Fibrillation ?

assistant: Atrial fibrillation (AF) usually causes the heart's lower chambers, the ventricles, to contract faster than normal.
                
When this happens, the ventricles can't completely fill with blood. Thus, they may not be able to pump enough blood to the lungs and body. This can lead to signs and symptoms, such as:
                
Palpitations (feelings that your heart is skipping a beat, fluttering, or beating too hard or fast)
                
Shortness of breath
                
Weakness or problems exercising
                
Chest pain
                
Dizziness or fainting
                
Fatigue (tiredness)
                
Confusion
                
Atrial Fibrillation Complications
                
AF has two major complicationsstroke and heart failure.
                
Stroke
                
During AF, the heart's upper chambers, the atria, don't pump all of their blood to the ventricles. Some blood pools in the atria. When this happens, a blood clot (also called a thrombus) can form.
                
If the clot breaks off and travels to the brain, it can cause a stroke. (A clot that forms in one part of the body and travels in the bloodstream to another part of the body is called an embolus.)
                
Blood-thinning medicines that reduce the risk of stroke are an important part of treatment for people who have AF.
                
Atrial Fibrillation and Stroke
                

                
Heart Failure
                
Heart failure occurs if the heart can't pump enough blood to meet the body's needs. AF can lead to heart failure because the ventricles are beating very fast and can't completely fill with blood. Thus, they may not be able to pump enough blood to the lungs and body.
                
Fatigue and shortness of breath are common symptoms of heart failure. A buildup of fluid in the lungs causes these symptoms. Fluid also can build up in the feet, ankles, and legs, causing weight gain.
                
Lifestyle changes, medicines, and procedures or surgery (rarely, a mechanical heart pump or heart transplant) are the main treatments for heart failure.
user: How to prevent Atrial Fibrillation ?

assistant: Following a healthy lifestyle and taking steps to lower your risk for heart disease may help you prevent atrial fibrillation (AF). These steps include:
                
Following a heart healthy diet that's low in saturated fat, trans fat, and cholesterol. A healthy diet includes a variety of whole grains, fruits, and vegetables daily.
                
Not smoking.
                
Being physically active.
                
Maintaining a healthy weight.
                
If you already have heart disease or other AF risk factors, work with your doctor to manage your condition. In addition to adopting the healthy habits above, which can help control heart disease, your doctor may advise you to: 
                
Follow the DASH eating plan to help lower your blood pressure.
                
Keep your cholesterol and triglycerides at healthy levels with dietary changes and medicines (if prescribed).
                
Limit or avoid alcohol.
                
Control your blood sugar level if you have diabetes.
                
Get ongoing medical care and take your medicines as prescribed.

user: What causes Tetralogy of Fallot ?

assistant: Doctors often don't know what causes tetralogy of Fallot and other congenital heart defects.
                
Some conditions or factors that occur during pregnancy may raise your risk of having a child who has tetralogy of Fallot. These conditions and factors include:
                
German measles (rubella) and some other viral illnesses
                
Poor nutrition
                
Alcohol use
                
Age (being older than 40)
                
Diabetes
                
Heredity may play a role in causing tetralogy of Fallot. An adult who has tetralogy of Fallot may be more likely than other people to have a baby with the condition.
                
Children who have certain genetic disorders, such as Down syndrome and DiGeorge syndrome, often have congenital heart defects, including tetralogy of Fallot.
                
Researchers continue to search for the causes of tetralogy of Fallot and other congenital heart defects.
user: What are the symptoms of Tetralogy of Fallot ?

assistant: Cyanosis is an important sign of tetralogy of Fallot. Cyanosis is a bluish tint to the skin, lips, and fingernails. Low oxygen levels in the blood cause cyanosis.
                
Babies who have unrepaired tetralogy of Fallot sometimes have "tet spells." These spells happen in response to an activity like crying or having a bowel movement.
                
A tet spell occurs when the oxygen level in the blood suddenly drops. This causes the baby to become very blue. The baby also may:
                
Have a hard time breathing
                
Become very tired and limp
                
Not respond to a parent's voice or touch
                
Become very fussy
                
Pass out
                
In years past, when tetralogy of Fallot wasn't treated in infancy, children would get very tired during exercise and could faint. Now, doctors repair tetralogy of Fallot in infancy to prevent these symptoms.
                
Another common sign of tetralogy of Fallot is a heart murmur. A heart murmur is an extra or unusual sound that doctors might hear while listening to the heart.
                
The sound occurs because the heart defect causes abnormal blood flow through the heart. However, not all heart murmurs are signs of congenital heart defects. Many healthy children have heart murmurs.
                
Babies who have tetralogy of Fallot may tire easily while feeding. Thus, they may not gain weight or grow as quickly as children who have healthy hearts. Also, normal growth depends on a normal workload for the heart and normal flow of oxygen-rich blood to all parts of the body.
                
Children who have tetralogy of Fallot also may have clubbing. Clubbing is the widening or rounding of the skin or bone around the tips of the fingers.
user: What is (are) Heart Murmur ?

assistant: A heart murmur is an extra or unusual sound heard during a heartbeat. Murmurs range from very faint to very loud. Sometimes they sound like a whooshing or swishing noise.
                
Normal heartbeats make a "lub-DUPP" or "lub-DUB" sound. This is the sound of the heart valves closing as blood moves through the heart. Doctors can hear these sounds and heart murmurs using a stethoscope.
                
Overview
                
The two types of heart murmurs are innocent (harmless) and abnormal.
                
Innocent heart murmurs aren't caused by heart problems. These murmurs are common in healthy children. Many children will have heart murmurs heard by their doctors at some point in their lives.
                
People who have abnormal heart murmurs may have signs or symptoms of heart problems. Most abnormal murmurs in children are caused by congenital (kon-JEN-ih-tal) heart defects. These defects are problems with the heart's structure that are present at birth.
                
In adults, abnormal heart murmurs most often are caused by acquired heart valve disease. This is heart valve disease that develops as the result of another condition. Infections, diseases, and aging can cause heart valve disease.
                
Outlook
                
A heart murmur isn't a disease, and most murmurs are harmless. Innocent murmurs don't cause symptoms. Having one doesn't require you to limit your physical activity or do anything else special. Although you may have an innocent murmur throughout your life, you won't need treatment for it.
                
The outlook and treatment for abnormal heart murmurs depend on the type and severity of the heart problem causing them.
user: What are the symptoms of Heart Murmur ?

assistant: People who have innocent (harmless) heart murmurs don't have any signs or symptoms other than the murmur itself. This is because innocent heart murmurs aren't caused by heart problems.
                
People who have abnormal heart murmurs may have signs or symptoms of the heart problems causing the murmurs. These signs and symptoms may include:
                
Poor eating and failure to grow normally (in infants)
                
Shortness of breath, which may occur only with physical exertion
                
Excessive sweating with minimal or no exertion
                
Chest pain
                
Dizziness or fainting
                
A bluish color on the skin, especially on the fingertips and lips
                
Chronic cough
                
Swelling or sudden weight gain
                
Enlarged liver
                
Enlarged neck veins
                
Signs and symptoms depend on the problem causing the heart murmur and its severity.
user: What are the treatments for Heart Murmur ?

assistant: A heart murmur isn't a disease. It's an extra or unusual sound heard during the heartbeat. Thus, murmurs themselves don't require treatment. However, if an underlying condition is causing a heart murmur, your doctor may recommend treatment for that condition.
                
Innocent (Harmless) Heart Murmurs
                
Healthy children who have innocent (harmless) heart murmurs don't need treatment. Their heart murmurs aren't caused by heart problems or other conditions.
                
Pregnant women who have innocent heart murmurs due to extra blood volume also don't need treatment. Their heart murmurs should go away after pregnancy.
                
Abnormal Heart Murmurs
                
If you or your child has an abnormal heart murmur, your doctor will recommend treatment for the disease or condition causing the murmur.
                
Some medical conditions, such as anemia or hyperthyroidism, can cause heart murmurs that aren't related to heart disease. Treating these conditions should make the heart murmur go away.
                
If a congenital heart defect is causing a heart murmur, treatment will depend on the type and severity of the defect. Treatment may include medicines or surgery. For more information about treatments for congenital heart defects, go to the Health Topics Congenital Heart Defects article.
                
If acquired heart valve disease is causing a heart murmur, treatment usually will depend on the type, amount, and severity of the disease.
                
Currently, no medicines can cure heart valve disease. However, lifestyle changes and medicines can treat symptoms and help delay complications. Eventually, though, you may need surgery to repair or replace a faulty heart valve.
                
For more information about treatments for heart valve disease, go to the Health Topics Heart Valve Disease article.
user: What causes Marfan Syndrome ?

assistant: Marfan syndrome is a genetic disorder. A mutation, or change, in the gene that controls how the body makes fibrillin causes Marfan syndrome. Fibrillin is a protein that plays a major role in your body's connective tissue.
                
Most people who have Marfan syndrome inherit it from their parents. If you have the condition, you have a 50 percent chance of passing the altered gene to each of your children.
                
Sometimes Marfan syndrome isn't inherited. The mutation in the fibrillin gene occurs in the egg or sperm cells. If a child is conceived, the altered gene may be passed on to the child. The risk of that child's brothers or sisters having Marfan syndrome is low.
user: Who is at risk for Marfan Syndrome? ?

assistant: People at highest risk for Marfan syndrome are those who have a family history of the condition. If you have Marfan syndrome, you have a 50 percent chance of passing the altered gene to each of your children.
                
Marfan syndrome affects about 1 out of every 5,000 people in the United States. Men, women, and children, and people of all races, can have the condition.
user: What is (are) Heart Palpitations ?

assistant: Palpitations (pal-pi-TA-shuns) are feelings that your heart is skipping a beat, fluttering, or beating too hard or too fast. You may have these feelings in your chest, throat, or neck. They can occur during activity or even when you're sitting still or lying down.
                
Overview
                
Many things can trigger palpitations, including:
                
Strong emotions
                
Vigorous physical activity
                
Medicines such as diet pills and decongestants
                
Caffeine, alcohol, nicotine, and illegal drugs
                
Certain medical conditions, such as thyroid disease or anemia (uh-NEE-me-uh)
                
These factors can make the heart beat faster or stronger than usual, or they can cause premature (extra) heartbeats. In these situations, the heart is still working normally. Thus, these palpitations usually are harmless.
                
Some palpitations are symptoms of arrhythmias (ah-RITH-me-ahs). Arrhythmias are problems with the rate or rhythm of the heartbeat.
                
Some arrhythmias are signs of heart conditions, such as heart attack, heart failure, heart valve disease, or heart muscle disease. However, less than half of the people who have palpitations have arrhythmias.
                
You can take steps to reduce or prevent palpitations. Try to avoid things that trigger them (such as stress and stimulants) and treat related medical conditions.
                
Outlook
                
Palpitations are very common. They usually aren't serious or harmful, but they can be bothersome. If you have them, your doctor can decide whether you need treatment or ongoing care.
user: Who is at risk for Heart Palpitations? ?

assistant: Some people may be more likely than others to have palpitations. People at increased risk include those who:
                
Have anxiety or panic attacks, or people who are highly stressed
                
Take certain medicines or stimulants
                
Have certain medical conditions that aren't related to heart problems, such as an overactive thyroid
                
Have certain heart problems, such as arrhythmias (irregular heartbeats), a previous heart attack, heart failure, heart valve disease, or heart muscle disease
                
Women who are pregnant, menstruating, or perimenopausal also may be at higher risk for palpitations because of hormonal changes. Some palpitations that occur during pregnancy may be due to anemia.
                
For more information about these risk factors, go to "What Causes Palpitations?"
user: What are the symptoms of Heart Palpitations ?

assistant: Symptoms of palpitations include feelings that your heart is:
                
Skipping a beat
                
Fluttering
                
Beating too hard or too fast
                
You may have these feelings in your chest, throat, or neck. They can occur during activity or even when you're sitting still or lying down.
                
Palpitations often are harmless, and your heart is working normally. However, these feelings can be a sign of a more serious problem if you also:
                
Feel dizzy or confused
                
Are light-headed, think you may faint, or do faint
                
Have trouble breathing
                
Have pain, pressure, or tightness in your chest, jaw, or arms
                
Feel short of breath
                
Have unusual sweating
                
Your doctor may have already told you that your palpitations are harmless. Even so, see your doctor again if your palpitations:
                
Start to occur more often or are more noticeable or bothersome
                
Occur with other symptoms, such as those listed above
                
Your doctor will want to check whether your palpitations are the symptom of a heart problem, such as an arrhythmia (irregular heartbeat).
user: What are the treatments for Heart Palpitations ?

assistant: Treatment for palpitations depends on their cause. Most palpitations are harmless and often go away on their own. In these cases, no treatment is needed.
                
Avoiding Triggers
                
Your palpitations may be harmless but bothersome. If so, your doctor may suggest avoiding things that trigger them. For examples, your doctor may advise you to:
                
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.
                
Treating Medical Conditions That May Cause Palpitations
                
Work with your doctor to control medical conditions that can cause palpitations, such as an overactive thyroid. If you're taking medicine that's causing palpitations, your doctor will try to find a different medicine for you.
                
If your palpitations are caused by an arrhythmia (irregular heartbeat), your doctor may recommend medicines or procedures to treat the problem. For more information, go to the Health Topics Arrhythmia article.
