Question:  What is (are) Holes in the Heart ?
Answer: Holes in the heart are simple congenital (kon-JEN-ih-tal) heart defects. Congenital heart defects are problems with the heart's structure that are present at birth. These defects change the normal flow of blood through the heart.
                
The heart has two sides, separated by an inner wall called the septum. With each heartbeat, the right side of the heart receives oxygen-poor blood from the body and pumps it to the lungs. The left side of the heart receives oxygen-rich blood from the lungs and pumps it to the body.
                
The septum prevents mixing of blood between the two sides of the heart. However, some babies are born with holes in the upper or lower septum.
                
A hole in the septum between the heart's two upper chambers is called an atrial septal defect (ASD). A hole in the septum between the heart's two lower chambers is called a ventricular septal defect (VSD).
                
ASDs and VSDs allow blood to pass from the left side of the heart to the right side. Thus, oxygen-rich blood mixes with oxygen-poor blood. As a result, some oxygen-rich blood is pumped to the lungs instead of the body.
                
Over the past few decades, the diagnosis and treatment of ASDs and VSDs have greatly improved. Children who have simple congenital heart defects can survive to adulthood. They can live normal, active lives because their heart defects close on their own or have been repaired.
Question:  What causes Holes in the Heart ?
Answer: Mothers of children who are born with atrial septal defects (ASDs), ventricular septal defects (VSDs), or other heart defects may think they did something wrong during their pregnancies. However, most of the time, doctors don't know why congenital heart defects occur.
                
Heredity may play a role in some heart defects. For example, a parent who has a congenital heart defect is slightly more likely than other people to have a child who has the problem. Very rarely, more than one child in a family is born with a heart defect.
                
Children who have genetic disorders, such as Down syndrome, often have congenital heart defects. Half of all babies who have Down syndrome have congenital heart defects.
                
Smoking during pregnancy also has been linked to several congenital heart defects, including septal defects.
                
Scientists continue to search for the causes of congenital heart defects.
Question:  What are the symptoms of Holes in the Heart ?
Answer: Atrial Septal Defect
                
Many babies who are born with atrial septal defects (ASDs) have no signs or symptoms. However, as they grow, these children may be small for their age. 
                
When signs and symptoms do occur, a heart murmur is the most common. A heart murmur is an extra or unusual sound heard during a heartbeat.
                
Often, a heart murmur is the only sign of an ASD. However, not all murmurs are signs of congenital heart defects. Many healthy children have heart murmurs. Doctors can listen to heart murmurs and tell whether they're harmless or signs of heart problems.
                
If a large ASD isn't repaired, the extra blood flow to the right side of the heart can damage the heart and lungs and cause heart failure. This generally doesn't occur until adulthood. Signs and symptoms of heart failure include:
                
Fatigue (tiredness)
                
Tiring easily during physical activity
                
Shortness of breath
                
A buildup of blood and fluid in the lungs
                
Swelling in the ankles, feet, legs, abdomen, and veins in the neck
                
Ventricular Septal Defect
                
Babies born with ventricular septal defects (VSDs) usually have heart murmurs. Murmurs may be the first and only sign of a VSD. Heart murmurs often are present right after birth in many infants. However, the murmurs may not be heard until the babies are 6 to 8 weeks old.
                
Most newborns who have VSDs don't have heart-related symptoms. However, babies who have medium or large VSDs can develop heart failure. Signs and symptoms of heart failure usually occur during the baby's first 2 months of life.
                
The signs and symptoms of heart failure due to VSD are similar to those listed above for ASD, but they occur in infancy.
                
A major sign of heart failure in infancy is poor feeding and growth. VSD signs and symptoms are rare after infancy. This is because the defects either decrease in size on their own or they're repaired.
Question:  What is (are) Congenital Heart Defects ?
Answer: Congenital (kon-JEN-ih-tal) heart defects are problems with the heart's structure that are present at birth. These defects can involve:
                
The interior walls of the heart
                
The valves inside the heart
                
The arteries and veins that carry blood to the heart or the body
                
Congenital heart defects change the normal flow of blood through the heart.
                
There are many types of congenital heart defects. They range from simple defects with no symptoms to complex defects with severe, life-threatening symptoms.
                
Congenital heart defects are the most common type of birth defect. They affect 8 out of every 1,000 newborns. Each year, more than 35,000 babies in the United States are born with congenital heart defects.
                
Many of these defects are simple conditions. They need no treatment or are easily fixed. Some babies are born with complex congenital heart defects. These defects require special medical care soon after birth.
                
The diagnosis and treatment of complex heart defects has greatly improved over the past few decades. As a result, almost all children who have complex heart defects survive to adulthood and can live active, productive lives.
                
Most people who have complex heart defects continue to need special heart care throughout their lives. They may need to pay special attention to how their condition affects issues such as health insurance, employment, birth control and pregnancy, and other health issues.
                
In the United States, more than 1 million adults are living with congenital heart defects.
Question:  What causes Congenital Heart Defects ?
Answer: If your child has a congenital heart defect, you may think you did something wrong during your pregnancy to cause the problem. However, doctors often don't know why congenital heart defects occur.
                
Heredity may play a role in some heart defects. For example, a parent who has a congenital heart defect may be more likely than other people to have a child with the defect. Rarely, more than one child in a family is born with a heart defect.
                
Children who have genetic disorders, such as Down syndrome, often have congenital heart defects. In fact, half of all babies who have Down syndrome have congenital heart defects.
                
Smoking during pregnancy also has been linked to several congenital heart defects, including septal defects.
                
Researchers continue to search for the causes of congenital heart defects.
Question:  What are the symptoms of Congenital Heart Defects ?
Answer: Many congenital heart defects cause few or no signs and symptoms. A doctor may not even detect signs of a heart defect during a physical exam.
                
Some heart defects do cause signs and symptoms. They depend on the number, type, and severity of the defects. Severe defects can cause signs and symptoms, usually in newborns. These signs and symptoms may include:
                
Rapid breathing
                
Cyanosis (a bluish tint to the skin, lips, and fingernails)
                
Fatigue (tiredness)
                
Poor blood circulation
                
Congenital heart defects don't cause chest pain or other painful symptoms.
                
Heart defects can cause heart murmurs (extra or unusual sounds heard during a heartbeat). Doctors can hear heart murmurs using a stethoscope. However, not all murmurs are signs of congenital heart defects. Many healthy children have heart murmurs.
                
Normal growth and development depend on a normal workload for the heart and normal flow of oxygen-rich blood to all parts of the body. Babies who have congenital heart defects may have cyanosis and tire easily while feeding. As a result, they may not gain weight or grow as they should.
                
Older children who have congenital heart defects may get tired easily or short of breath during physical activity.
                
Many types of congenital heart defects cause the heart to work harder than it should. With severe defects, this can lead to heart failure. Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs. Symptoms of heart failure include:
                
Shortness of breath or trouble breathing
                
Fatigue with physical activity
                
A buildup of blood and fluid in the lungs
                
Swelling in the ankles, feet, legs, abdomen, and veins in the neck
Question:  What is (are) Bronchitis ?
Answer: Espaol
                
Bronchitis (bron-KI-tis) is a condition in which the bronchial tubes become inflamed. These tubes carry air to your lungs. (For more information about the bronchial tubes and airways, go to the Diseases and Conditions Index How the Lungs Work article.)
                
People who have bronchitis often have a cough that brings up mucus. Mucus is a slimy substance made by the lining of the bronchial tubes. Bronchitis also may cause wheezing (a whistling or squeaky sound when you breathe), chest pain or discomfort, a low fever, and shortness of breath.
                
Bronchitis
                

                
Overview
                
The two main types of bronchitis are acute (short term) and chronic (ongoing).
                
Acute Bronchitis
                
Infections or lung irritants cause acute bronchitis. The same viruses that cause colds and the flu are the most common cause of acute bronchitis. These viruses are spread through the air when people cough. They also are spread through physical contact (for example, on hands that have not been washed).
                
Sometimes bacteria cause acute bronchitis.
                
Acute bronchitis lasts from a few days to 10 days. However, coughing may last for several weeks after the infection is gone.
                
Several factors increase your risk for acute bronchitis. Examples include exposure to tobacco smoke (including secondhand smoke), dust, fumes, vapors, and air pollution. Avoiding these lung irritants as much as possible can help lower your risk for acute bronchitis.
                
Most cases of acute bronchitis go away within a few days. If you think you have acute bronchitis, see your doctor. He or she will want to rule out other, more serious health conditions that require medical care.
                
Chronic Bronchitis
                
Chronic bronchitis is an ongoing, serious condition. It occurs if the lining of the bronchial tubes is constantly irritated and inflamed, causing a long-term cough with mucus. Smoking is the main cause of chronic bronchitis.
                
Viruses or bacteria can easily infect the irritated bronchial tubes. If this happens, the condition worsens and lasts longer. As a result, people who have chronic bronchitis have periods when symptoms get much worse than usual.
                
Chronic bronchitis is a serious, long-term medical condition. Early diagnosis and treatment, combined with quitting smoking and avoiding secondhand smoke, can improve quality of life. The chance of complete recovery is low for people who have severe chronic bronchitis.
Question:  What causes Bronchitis ?
Answer: Acute Bronchitis
                
Infections or lung irritants cause acute bronchitis. The same viruses that cause colds and the flu are the most common cause of acute bronchitis. Sometimes bacteria can cause the condition.
                
Certain substances can irritate your lungs and airways and raise your risk for acute bronchitis. For example, inhaling or being exposed to tobacco smoke, dust, fumes, vapors, or air pollution raises your risk for the condition. These lung irritants also can make symptoms worse.
                
Being exposed to a high level of dust or fumes, such as from an explosion or a big fire, also may lead to acute bronchitis.
                
Chronic Bronchitis
                
Repeatedly breathing in fumes that irritate and damage lung and airway tissues causes chronic bronchitis. Smoking is the major cause of the condition.
                
Breathing in air pollution and dust or fumes from the environment or workplace also can lead to chronic bronchitis.
                
People who have chronic bronchitis go through periods when symptoms become much worse than usual. During these times, they also may have acute viral or bacterial bronchitis.
Question:  Who is at risk for Bronchitis? ?
Answer: Bronchitis is a very common condition. Millions of cases occur every year.
                
Elderly people, infants, and young children are at higher risk for acute bronchitis than people in other age groups.
                
People of all ages can develop chronic bronchitis, but it occurs more often in people who are older than 45. Also, many adults who develop chronic bronchitis are smokers. Women are more than twice as likely as men to be diagnosed with chronic bronchitis.
                
Smoking and having an existing lung disease greatly increase your risk for bronchitis. Contact with dust, chemical fumes, and vapors from certain jobs also increases your risk for the condition. Examples include jobs in coal mining, textile manufacturing, grain handling, and livestock farming.
                
Air pollution, infections, and allergies can worsen the symptoms of chronic bronchitis, especially if you smoke.
Question:  What are the symptoms of Bronchitis ?
Answer: Acute Bronchitis
                
Acute bronchitis caused by an infection usually develops after you already have a cold or the flu. Symptoms of a cold or the flu include sore throat, fatigue (tiredness), fever, body aches, stuffy or runny nose, vomiting, and diarrhea.
                
The main symptom of acute bronchitis is a persistent cough, which may last 10 to 20 days. The cough may produce clear mucus (a slimy substance). If the mucus is yellow or green, you may have a bacterial infection as well. Even after the infection clears up, you may still have a dry cough for days or weeks.
                
Other symptoms of acute bronchitis include wheezing (a whistling or squeaky sound when you breathe), low fever, and chest tightness or pain.
                
If your acute bronchitis is severe, you also may have shortness of breath, especially with physical activity.
                
Chronic Bronchitis
                
The signs and symptoms of chronic bronchitis include coughing, wheezing, and chest discomfort. The coughing may produce large amounts of mucus. This type of cough often is called a smoker's cough.
Question:  How to diagnose Bronchitis ?
Answer: Your doctor usually will diagnose bronchitis based on your signs and symptoms. He or she may ask questions about your cough, such as how long you've had it, what you're coughing up, and how much you cough.
                
Your doctor also will likely ask:
                
About your medical history
                
Whether you've recently had a cold or the flu
                
Whether you smoke or spend time around others who smoke
                
Whether you've been exposed to dust, fumes, vapors, or air pollution
                
Your doctor will use a stethoscope to listen for wheezing (a whistling or squeaky sound when you breathe) or other abnormal sounds in your lungs. He or she also may:
                
Look at your mucus to see whether you have a bacterial infection
                
Test the oxygen levels in your blood using a sensor attached to your fingertip or toe
                
Recommend a chest x ray, lung function tests, or blood tests
Question:  What are the treatments for Bronchitis ?
Answer: The main goals of treating acute and chronic bronchitis are to relieve symptoms and make breathing easier.
                
If you have acute bronchitis, your doctor may recommend rest, plenty of fluids, and aspirin (for adults) or acetaminophen to treat fever.
                
Antibiotics usually aren't prescribed for acute bronchitis. This is because they don't work against virusesthe most common cause of acute bronchitis. However, if your doctor thinks you have a bacterial infection, he or she may prescribe antibiotics.
                
A humidifier or steam can help loosen mucus and relieve wheezing and limited air flow. If your bronchitis causes wheezing, you may need an inhaled medicine to open your airways. You take this medicine using an inhaler. This device allows the medicine to go straight to your lungs.
                
Your doctor also may prescribe medicines to relieve or reduce your cough and treat your inflamed airways (especially if your cough persists).
                
If you have chronic bronchitis and also have been diagnosed with COPD (chronic obstructive pulmonary disease), you may need medicines to open your airways and help clear away mucus. These medicines include bronchodilators (inhaled) and steroids (inhaled or pill form).
                
If you have chronic bronchitis, your doctor may prescribe oxygen therapy. This treatment can help you breathe easier, and it provides your body with needed oxygen.
                
One of the best ways to treat acute and chronic bronchitis is to remove the source of irritation and damage to your lungs. If you smoke, it's very important to quit.
                
Talk with your doctor about programs and products that can help you quit smoking. Try to avoid secondhand smoke and other lung irritants, such as dust, fumes, vapors, and air pollution.
                
For more information about how to quit smoking, go to the Diseases and Conditions Index Smoking and Your Heart article and the National Heart, Lung, and Blood Institute's "Your Guide to a Healthy Heart." Although these resources focus on heart health, they include general information about how to quit smoking.
Question:  How to prevent Bronchitis ?
Answer: You can't always prevent acute or chronic bronchitis. However, you can take steps to lower your risk for both conditions. The most important step is to quit smoking or not start smoking.
                
For more information about how to quit smoking, go to the Diseases and Conditions Index Smoking and Your Heart article and the National Heart, Lung, and Blood Institute's "Your Guide to a Healthy Heart." Although these resources focus on heart health, they include general information about how to quit smoking.
                
Also, try to avoid other lung irritants, such as secondhand smoke, dust, fumes, vapors, and air pollution. For example, wear a mask over your mouth and nose when you use paint, paint remover, varnish, or other substances with strong fumes. This will help protect your lungs.
                
Wash your hands often to limit your exposure to germs and bacteria. Your doctor also may advise you to get a yearly flu shot and a pneumonia vaccine.
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?")
