Question: What is (are) Overweight and Obesity ?
Answer: Espaol
                
The terms "overweight" and "obesity" refer to body weight thats greater than what is considered healthy for a certain height.
                
The most useful measure of overweight and obesity is body mass index (BMI). BMI is calculated from your height and weight. For more information about BMI, go to "How Are Overweight and Obesity Diagnosed?"
                
Overview
                
Millions of Americans and people worldwide are overweight or obese. Being overweight or obese puts you at risk for many health problems. The more body fat that you have and the more you weigh, the more likely you are to develop:
                
Coronary heart disease
                
High blood pressure
                
Type 2 diabetes
                
Gallstones
                
Breathing problems
                
Certain cancers
                
Your weight is the result of many factors. These factors include environment, family history and genetics, metabolism (the way your body changes food and oxygen into energy), behavior or habits, and more.
                
You can't change some factors, such as family history. However, you can change other factors, such as your lifestyle habits.
                
For example, follow a healthy eating plan and keep your calorie needs in mind. Be physically active and try to limit the amount of time that you're inactive.
                
Weight-loss medicines and surgery also are options for some people if lifestyle changes aren't enough.
                
Outlook
                
Reaching and staying at a healthy weight is a long-term challenge for people who are overweight or obese. But it also is a chance to lower your risk for other serious health problems. With the right treatment and motivation, it's possible to lose weight and lower your long-term disease risk.

Question: Who is at risk for Overweight and Obesity? ?
Answer: Overweight and obesity affect Americans of all ages, sexes, and racial/ethnic groups. This serious health problem has been growing over the last 30 years.
                
Adults
                
According to the National Health and Nutrition Examination Survey (NHANES) 20092010, almost 70 percent of Americans are overweight or obese. The survey also shows differences in overweight and obesity among racial/ethnic groups.
                
In women, overweight and obesity are highest among non-Hispanic Black women (about 82percent), compared with about 76 percent for Hispanic women and 64 percent for non-Hispanic White women.
                
In men, overweight and obesity are highest among Hispanic men (about 82percent), compared with about 74 percent for non-Hispanic White men and about 70 percent for non-Hispanic Black men.
                
Children and Teens
                
Children also have become heavier. In the past 30 years, obesity has tripled among school-aged children and teens.
                
According to NHANES 20092010, about 1 in 6 American children ages 219 are obese. The survey also suggests that overweight and obesity are having a greater effect on minority groups, including Blacks and Hispanics.

Question: What are the symptoms of Overweight and Obesity ?
Answer: Weight gain usually happens over time. Most people know when they've gained weight. Some of the signs of overweight or obesity include:
                
Clothes feeling tight and needing a larger size.
                
The scale showing that you've gained weight.
                
Having extra fat around the waist.
                
A higher than normal body mass index and waist circumference. (For more information, go to "How Are Overweight and Obesity Diagnosed?")

Question: How to prevent Overweight and Obesity ?
Answer: Following a healthy lifestyle can help you prevent overweight and obesity. Many lifestyle habits begin during childhood. Thus, parents and families should encourage their children to make healthy choices, such as following a healthy diet and being physically active.
                
Make following a healthy lifestyle a family goal. For example:
                
Follow a healthy eating plan. Make healthy food choices, keep your calorie needs and your family's calorie needs in mind, and focus on the balance of energy IN and energy OUT.
                
Focus on portion size. Watch the portion sizes in fast food and other restaurants. The portions served often are enough for two or three people. Children's portion sizes should be smaller than those for adults. Cutting back on portion size will help you balance energy IN and energy OUT.
                
Be active. Make personal and family time active. Find activities that everyone will enjoy. For example, go for a brisk walk, bike or rollerblade, or train together for a walk or run.
                
Reduce screen time. Limit the use of TVs, computers, DVDs, and videogames because they limit time for physical activity. Health experts recommend 2hours or less a day of screen time that's not work- or homework-related.
                
Keep track of your weight, body mass index, and waist circumference. Also, keep track of your children's growth.
                
Led by the National Heart, Lung, and Blood Institute, four Institutes from the National Institutes of Health have come together to promote We Can!Ways to Enhance Children's Activity & Nutrition.
                
We Can! is a national education program designed for parents and caregivers to help children 8 to 13 years old maintain a healthy weight. The evidence-based program offers parents and families tips and fun activities to encourage healthy eating, increase physical activity, and reduce time spent being inactive.
                
Currently, more than 140 community groups around the country are participating in We Can! programs for parents and youth. These community groups include hospitals, health departments, clinics, faith-based organizations, YMCAs, schools, and more.

Question: What is (are) Iron-Deficiency Anemia ?
Answer: Espaol
                
Iron-deficiency anemia is a common, easily treated condition that occurs if you don't have enough iron in your body. Low iron levels usually are due to blood loss, poor diet, or an inability to absorb enough iron from food.
                
Overview
                
Iron-deficiency anemia is a common type of anemia. The term "anemia" usually refers to a condition in which your blood has a lower than normal number of red blood cells. Red blood cells carry oxygen and remove carbon dioxide (a waste product) from your body.
                
Anemia also can occur if your red blood cells don't contain enough hemoglobin (HEE-muh-glow-bin). Hemoglobin is an iron-rich protein that carries oxygen from the lungs to the rest of the body.
                
Iron-deficiency anemia usually develops over time if your body doesn't have enough iron to build healthy red blood cells. Without enough iron, your body starts using the iron it has stored. Soon, the stored iron gets used up.
                
After the stored iron is gone, your body makes fewer red blood cells. The red blood cells it does make have less hemoglobin than normal.
                
Iron-deficiency anemia can cause fatigue (tiredness), shortness of breath, chest pain, and other symptoms. Severe iron-deficiency anemia can lead to heart problems, infections, problems with growth and development in children, and other complications.
                
Infants and young children and women are the two groups at highest risk for iron-deficiency anemia.
                
Outlook
                
Doctors usually can successfully treat iron-deficiency anemia. Treatment will depend on the cause and severity of the condition. Treatments may include dietary changes, medicines, and surgery.
                
Severe iron-deficiency anemia may require treatment in a hospital, blood transfusions, iron injections, or intravenous iron therapy.

Question: What causes Iron-Deficiency Anemia ?
Answer: Not having enough iron in your body causes iron-deficiency anemia. Lack of iron usually is due to blood loss, poor diet, or an inability to absorb enough iron from food.
                
Blood Loss
                
When you lose blood, you lose iron. If you don't have enough iron stored in your body to make up for the lost iron, you'll develop iron-deficiency anemia.
                
In women, long or heavy menstrual periods or bleeding fibroids in the uterus may cause low iron levels. Blood loss that occurs during childbirth is another cause of low iron levels in women.
                
Internal bleeding (bleeding inside the body) also may lead to iron-deficiency anemia. This type of blood loss isn't always obvious, and it may occur slowly. Some causes of internal bleeding are:
                
A bleeding ulcer, colon polyp, or colon cancer
                
Regular use of aspirin or other pain medicines, such as nonsteroidal anti-inflammatory drugs (for example, ibuprofen and naproxen)
                
Urinary tract bleeding
                
Blood loss from severe injuries, surgery, or frequent blood drawings also can cause iron-deficiency anemia.
                
Poor Diet
                
The best sources of iron are meat, poultry, fish, and iron-fortified foods (foods that have iron added). If you don't eat these foods regularly, or if you don't take an iron supplement, you're more likely to develop iron-deficiency anemia.
                
Vegetarian diets can provide enough iron if you eat the right foods. For example, good nonmeat sources of iron include iron-fortified breads and cereals, beans, tofu, dried fruits, and spinach and other dark green leafy vegetables.
                
During some stages of life, such as pregnancy and childhood, it may be hard to get enough iron in your diet. This is because your need for iron increases during these times of growth and development.
                
Inability To Absorb Enough Iron
                
Even if you have enough iron in your diet, your body may not be able to absorb it. This can happen if you have intestinal surgery (such as gastric bypass) or a disease of the intestine (such as Crohn's disease or celiac disease).
                
Prescription medicines that reduce acid in the stomach also can interfere with iron absorption.

Question: What are the symptoms of Iron-Deficiency Anemia ?
Answer: The signs and symptoms of iron-deficiency anemia depend on its severity. Mild to moderate iron-deficiency anemia may have no signs or symptoms.
                
When signs and symptoms do occur, they can range from mild to severe. Many of the signs and symptoms of iron-deficiency anemia apply to all types of anemia.
                
Signs and Symptoms of Anemia
                
The most common symptom of all types of anemia is fatigue (tiredness). Fatigue occurs because your body doesn't have enough red blood cells to carry oxygen to its many parts.
                
Also, the red blood cells your body makes have less hemoglobin than normal. Hemoglobin is an iron-rich protein in red blood cells. It helps red blood cells carry oxygen from the lungs to the rest of the body.
                
Anemia also can cause shortness of breath, dizziness, headache, coldness in your hands and feet, pale skin, chest pain, weakness, and fatigue (tiredness).
                
If you don't have enough hemoglobin-carrying red blood cells, your heart has to work harder to move oxygen-rich blood through your body. This can lead to irregular heartbeats called arrhythmias (ah-RITH-me-ahs), a heart murmur, an enlarged heart, or even heart failure.
                
In infants and young children, signs of anemia include poor appetite, slowed growth and development, and behavioral problems.
                
Signs and Symptoms of Iron Deficiency
                
Signs and symptoms of iron deficiency may include brittle nails, swelling or soreness of the tongue, cracks in the sides of the mouth, an enlarged spleen, and frequent infections.
                
People who have iron-deficiency anemia may have an unusual craving for nonfood items, such as ice, dirt, paint, or starch. This craving is called pica (PI-ka or PE-ka).
                
Some people who have iron-deficiency anemia develop restless legs syndrome (RLS). RLS is a disorder that causes a strong urge to move the legs. This urge to move often occurs with strange and unpleasant feelings in the legs. People who have RLS often have a hard time sleeping.
                
Iron-deficiency anemia can put children at greater risk for lead poisoning and infections.
                
Some signs and symptoms of iron-deficiency anemia are related to the condition's causes. For example, a sign of intestinal bleeding is bright red blood in the stools or black, tarry-looking stools.
                
Very heavy menstrual bleeding, long periods, or other vaginal bleeding may suggest that a woman is at risk for iron-deficiency anemia.

Question: How to prevent Iron-Deficiency Anemia ?
Answer: 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.

Question: What causes Atrial Fibrillation ?
Answer: 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.

Question: Who is at risk for Atrial Fibrillation? ?
Answer: 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.

Topic: Atrial Fibrillation
Source: NHLBI
Question: What are the symptoms of Atrial Fibrillation ?
Answer: 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.

Question: How to prevent Atrial Fibrillation ?
Answer: 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.
