What is (are) Asthma ?

Answer:
Espaol
                
Asthma (AZ-ma) is a chronic (long-term) lung disease that inflames and narrows the airways. Asthma causes recurring periods of wheezing (a whistling sound when you breathe), chest tightness, shortness of breath, and coughing. The coughing often occurs at night or early in the morning.
                
Asthma affects people of all ages, but it most often starts during childhood. In the United States, more than 25 million people are known to have asthma. About 7million of these people are children.
                
Overview
                
To understand asthma, it helps to know how the airways work. The airways are tubes that carry air into and out of your lungs. People who have asthma have inflamed airways. The inflammation makes the airways swollen and very sensitive. The airways tend to react strongly to certain inhaled substances.
                
When the airways react, the muscles around them tighten. This narrows the airways, causing less air to flow into the lungs. The swelling also can worsen, making the airways even narrower. Cells in the airways might make more mucus than usual. Mucus is a sticky, thick liquid that can further narrow the airways.
                
This chain reaction can result in asthma symptoms. Symptoms can happen each time the airways are inflamed.
                
Asthma
                

                
Sometimes asthma symptoms are mild and go away on their own or after minimal treatment with asthma medicine. Other times, symptoms continue to get worse.
                
When symptoms get more intense and/or more symptoms occur, you're having an asthma attack. Asthma attacks also are called flareups or exacerbations (eg-zas-er-BA-shuns).
                
Treating symptoms when you first notice them is important. This will help prevent the symptoms from worsening and causing a severe asthma attack. Severe asthma attacks may require emergency care, and they can be fatal.
                
Outlook
                
Asthma has no cure. Even when you feel fine, you still have the disease and it can flare up at any time.
                
However, with today's knowledge and treatments, most people who have asthma are able to manage the disease. They have few, if any, symptoms. They can live normal, active lives and sleep through the night without interruption from asthma.
                
If you have asthma, you can take an active role in managing the disease. For successful, thorough, and ongoing treatment, build strong partnerships with your doctor and other health care providers.
Question:
What causes Asthma ?

Answer:
The exact cause of asthma isn't known. Researchers think some genetic and environmental factors interact to cause asthma, most often early in life. These factors include:
                
An inherited tendency to develop allergies, called atopy (AT-o-pe)
                
Parents who have asthma
                
Certain respiratory infections during childhood
                
Contact with some airborne allergens or exposure to some viral infections in infancy or in early childhood when the immune system is developing
                
If asthma or atopy runs in your family, exposure to irritants (for example, tobacco smoke) may make your airways more reactive to substances in the air.
                
Some factors may be more likely to cause asthma in some people than in others. Researchers continue to explore what causes asthma.
                
The "Hygiene Hypothesis"
                
One theory researchers have for what causes asthma is the "hygiene hypothesis." They believe that our Western lifestylewith its emphasis on hygiene and sanitationhas resulted in changes in our living conditions and an overall decline in infections in early childhood.
                
Many young children no longer have the same types of environmental exposures and infections as children did in the past. This affects the way that young children's immune systems develop during very early childhood, and it may increase their risk for atopy and asthma. This is especially true for children who have close family members with one or both of these conditions.
Question:
Who is at risk for Asthma? ?

Answer:
Asthma affects people of all ages, but it most often starts during childhood. In the United States, more than 22 million people are known to have asthma. Nearly 6 million of these people are children.
                
Young children who often wheeze and have respiratory infectionsas well as certain other risk factorsare at highest risk of developing asthma that continues beyond 6 years of age. The other risk factors include having allergies, eczema (an allergic skin condition), or parents who have asthma.
                
Among children, more boys have asthma than girls. But among adults, more women have the disease than men. It's not clear whether or how sex and sex hormones play a role in causing asthma.
                
Most, but not all, people who have asthma have allergies.
                
Some people develop asthma because of contact with certain chemical irritants or industrial dusts in the workplace. This type of asthma is called occupational asthma.
Question:
What are the symptoms of Asthma ?

Answer:
Common signs and symptoms of asthma include:
                
Coughing. Coughing from asthma often is worse at night or early in the morning, making it hard to sleep.
                
Wheezing. Wheezing is a whistling or squeaky sound that occurs when you breathe.
                
Chest tightness. This may feel like something is squeezing or sitting on your chest.
                
Shortness of breath. Some people who have asthma say they can't catch their breath or they feel out of breath. You may feel like you can't get air out of your lungs.
                
Not all people who have asthma have these symptoms. Likewise, having these symptoms doesn't always mean that you have asthma. The best way to diagnose asthma for certain is to use a lung function test, a medical history (including type and frequency of symptoms), and a physical exam.
                
The types of asthma symptoms you have, how often they occur, and how severe they are may vary over time. Sometimes your symptoms may just annoy you. Other times, they may be troublesome enough to limit your daily routine.
                
Severe symptoms can be fatal. It's important to treat symptoms when you first notice them so they don't become severe.
                
With proper treatment, most people who have asthma can expect to have few, if any, symptoms either during the day or at night.
                
What Causes Asthma Symptoms To Occur?
                
Many things can trigger or worsen asthma symptoms. Your doctor will help you find out which things (sometimes called triggers) may cause your asthma to flare up if you come in contact with them. Triggers may include:
                
Allergens from dust, animal fur, cockroaches, mold, and pollens from trees, grasses, and flowers
                
Irritants such as cigarette smoke, air pollution, chemicals or dust in the workplace, compounds in home dcor products, and sprays (such as hairspray)
                
Medicines such as aspirin or other nonsteroidal anti-inflammatory drugs and nonselective beta-blockers
                
Sulfites in foods and drinks
                
Viral upper respiratory infections, such as colds
                
Physical activity, including exercise
                
Other health conditions can make asthma harder to manage. Examples of these conditions include a runny nose, sinus infections, reflux disease, psychological stress, and sleep apnea. These conditions need treatment as part of an overall asthma care plan.
                
Asthma is different for each person. Some of the triggers listed above may not affect you. Other triggers that do affect you may not be on the list. Talk with your doctor about the things that seem to make your asthma worse.
Question:
How to prevent Asthma ?

Answer:
You cant prevent asthma. However, you can take steps to control the disease and prevent its symptoms. For example:
                
Learn about your asthma and ways to control it.
                
Follow your written asthma action plan. (For a sample plan, go to the National Heart, Lung, and Blood Institute's "Asthma Action Plan.")
                
Use medicines as your doctor prescribes.
                
Identify and try to avoid things that make your asthma worse (asthma triggers). However, one trigger you should not avoid is physical activity. Physical activity is an important part of a healthy lifestyle. Talk with your doctor about medicines that can help you stay active.
                
Keep track of your asthma symptoms and level of control.
                
Get regular checkups for your asthma.

Question:
What is (are) Stroke ?

Answer:
A stroke occurs if the flow of oxygen-rich blood to a portion of the brain is blocked. Without oxygen, brain cells start to die after a few minutes. Sudden bleeding in the brain also can cause a stroke if it damages brain cells.
                
If brain cells die or are damaged because of a stroke, symptoms occur in the parts of the body that these brain cells control. Examples of stroke symptoms include sudden weakness; paralysis or numbness of the face, arms, or legs (paralysis is an inability to move); trouble speaking or understanding speech; and trouble seeing.
                
A stroke is a serious medical condition that requires emergency care. A stroke can cause lasting brain damage, long-term disability, or even death.
                
If you think you or someone else is having a stroke, call 911 right away. Do not drive to the hospital or let someone else drive you. Call an ambulance so that medical personnel can begin life-saving treatment on the way to the emergency room. During a stroke, every minute counts.
                
Overview
                
The two main types of stroke are ischemic (is-KE-mik) and hemorrhagic (hem-ah-RAJ-ik). Ischemic is the more common type of stroke.
                
An ischemic stroke occurs if an artery that supplies oxygen-rich blood to the brain becomes blocked. Blood clots often cause the blockages that lead to ischemic strokes.
                
A hemorrhagic stroke occurs if an artery in the brain leaks blood or ruptures (breaks open). The pressure from the leaked blood damages brain cells. High blood pressure and aneurysms (AN-u-risms) are examples of conditions that can cause hemorrhagic strokes. (Aneurysms are balloon-like bulges in an artery that can stretch and burst.)
                
Another condition thats similar to a stroke is a transient ischemic attack, also called a TIA or mini-stroke. A TIA occurs if blood flow to a portion of the brain is blocked only for a short time. Thus, damage to the brain cells isnt permanent (lasting).
                
Like ischemic strokes, TIAs often are caused by blood clots. Although TIAs are not full-blown strokes, they greatly increase the risk of having a stroke. If you have a TIA, its important for your doctor to find the cause so you can take steps to prevent a stroke.
                
Both strokes and TIAs require emergency care.
                
Outlook
                
Stroke is a leading cause of death in the United States. Many factors can raise your risk of having a stroke. Talk with your doctor about how you can control these risk factors and help prevent a stroke.
                
If you have a stroke, prompt treatment can reduce damage to your brain and help you avoid lasting disabilities. Prompt treatment also may help prevent another stroke.
                
Researchers continue to study the causes and risk factors for stroke. Theyre also finding new and better treatments and new ways to help the brain repair itself after a stroke.
Question:
What are the symptoms of Stroke ?

Answer:
The signs and symptoms of a stroke often develop quickly. However, they can develop over hours or even days.
                
The type of symptoms depends on the type of stroke and the area of the brain thats affected. How long symptoms last and how severe they are vary among different people.
                
Signs and symptoms of a stroke may include:
                
Sudden weakness
                
Paralysis (an inability to move) or numbness of the face, arms, or legs, especially on one side of the body
                
Confusion
                
Trouble speaking or understanding speech
                
Trouble seeing in one or both eyes
                
Problems breathing
                
Dizziness, trouble walking, loss of balance or coordination, and unexplained falls
                
Loss of consciousness
                
Sudden and severe headache
                
A transient ischemic attack (TIA) has the same signs and symptoms as a stroke. However, TIA symptoms usually last less than 12 hours (although they may last up to 24 hours). A TIA may occur only once in a persons lifetime or more often.
                
At first, it may not be possible to tell whether someone is having a TIA or stroke. All stroke-like symptoms require medical care.
                
If you think you or someone else is having a TIA or stroke, call 911 right away. Do not drive to the hospital or let someone else drive you. Call an ambulance so that medical personnel can begin life-saving treatment on the way to the emergency room. During a stroke, every minute counts.
                
Stroke Complications
                
After youve had a stroke, you may develop other complications, such as:
                
Blood clots and muscle weakness. Being immobile (unable to move around) for a long time can raise your risk of developing blood clots in the deep veins of the legs. Being immobile also can lead to muscle weakness and decreased muscle flexibility.
                
Problems swallowing and pneumonia. If a stroke affects the muscles used for swallowing, you may have a hard time eating or drinking. You also may be at risk of inhaling food or drink into your lungs. If this happens, you may develop pneumonia.
                
Loss of bladder control. Some strokes affect the muscles used to urinate. You may need a urinary catheter (a tube placed into the bladder) until you can urinate on your own. Use of these catheters can lead to urinary tract infections. Loss of bowel control or constipation also may occur after a stroke.
Question:
How to prevent Stroke ?

Answer:
Taking action to control your risk factors can help prevent or delay a stroke. If youve already had a stroke, these actions can help prevent another one.
                
Be physically active. Physical activity can improve your fitness level and health. Talk with your doctor about what types and amounts of activity are safe for you.
                
Dont smoke, or if you smoke or use tobacco, quit. Smoking can damage and tighten blood vessels and raise your risk of stroke. Talk with your doctor about programs and products that can help you quit. Also, secondhand smoke can damage the bloodvessels.
                
Maintain a healthy weight. If youre overweight or obese, work with your doctor to create a reasonable weight loss plan. Controlling your weight helps you control risk factors for stroke.
                
Make heart-healthy eating choices. Heart-healthy eating can help lower your risk or prevent a stroke.
                
Manage stress. Use techniques to lower your stress levels.
                
If you or someone in your family has had a stroke, be sure to tell your doctor. By knowing your family history of stroke, you may be able to lower your risk factors and prevent or delay a stroke. If youve had a transient ischemic attack (TIA), dont ignore it. TIAs are warnings, and its important for your doctor to find the cause of the TIA so you can take steps to prevent a stroke.
Question:
How to prevent Diabetic Heart Disease ?

Answer:
Taking action to control risk factors can help prevent or delay heart disease in people who have diabetes and in those who don't. Your risk of heart disease increases with the number of risk factors you have.
                
One step you can take is to adopt a healthy lifestyle. A healthy lifestyle should be part of a lifelong approach to healthy living. A healthy lifestyle includes:
                
Following a healthy diet
                
Maintaining a healthy weight
                
Being physically active
                
Quitting smoking
                
Managing stress
                
You also should know your family history of diabetes and heart disease. If you or someone in your family has diabetes, heart disease, or both, let your doctor know.
                
Your doctor may prescribe medicines to control certain risk factors, such as high blood pressure and high blood cholesterol. Take all of your medicines exactly as your doctor advises.
                
People who have diabetes also need good blood sugar control. Controlling your blood sugar level is good for heart health. Ask your doctor about the best ways to control your blood sugar level.

Question:
What is (are) Bronchopulmonary Dysplasia ?

Answer:
Bronchopulmonary (BRONG-ko-PUL-mo-NAR-e) dysplasia (dis-PLA-ze-ah), or BPD, is a serious lung condition that affects infants. BPD mostly affects premature infants who need oxygen therapy (oxygen given through nasal prongs, a mask, or a breathing tube).
                
Most infants who develop BPD are born more than 10 weeks before their due dates, weigh less than 2 pounds (about 1,000 grams) at birth, and have breathing problems. Infections that occur before or shortly after birth also can contribute to BPD.
                
Some infants who have BPD may need long-term breathing support from nasal continuous positive airway pressure (NCPAP) machines or ventilators.
                
Overview
                
Many babies who develop BPD are born with serious respiratory distress syndrome (RDS). RDS is a breathing disorder that mostly affects premature newborns. These infants' lungs aren't fully formed or aren't able to make enough surfactant (sur-FAK-tant).
                
Surfactant is a liquid that coats the inside of the lungs. It helps keep them open so an infant can breathe in air once he or she is born.
                
Without surfactant, the lungs collapse, and the infant has to work hard to breathe. He or she might not be able to breathe in enough oxygen to support the body's organs. Without proper treatment, the lack of oxygen may damage the infant's brain and other organs.
                
Babies who have RDS are treated with surfactant replacement therapy. They also may need oxygen therapy. Shortly after birth, some babies who have RDS also are treated with NCPAP or ventilators (machines that support breathing).
                
Often, the symptoms of RDS start to improve slowly after about a week. However, some babies get worse and need more oxygen or breathing support from NCPAP or a ventilator.
                
If premature infants still require oxygen therapy by the time they reach their original due dates, they're diagnosed with BPD.
                
Outlook
                
Advances in care now make it possible for more premature infants to survive. However, these infants are at high risk for BPD.
                
Most babies who have BPD get better in time, but they may need treatment for months or even years. They may continue to have lung problems throughout childhood and even into adulthood. There's some concern about whether people who had BPD as babies can ever have normal lung function.
                
As children who have BPD grow, their parents can help reduce the risk of BPD complications. Parents can encourage healthy eating habits and good nutrition. They also can avoid cigarette smoke and other lung irritants.
Question:
What causes Bronchopulmonary Dysplasia ?

Answer:
Bronchopulmonary dysplasia (BPD) develops as a result of an infant's lungs becoming irritated or inflamed.
                
The lungs of premature infants are fragile and often aren't fully developed. They can easily be irritated or injured within hours or days of birth. Many factors can damage premature infants' lungs.
                
Ventilation
                
Newborns who have breathing problems or can't breathe on their own may need ventilator support. Ventilators are machines that use pressure to blow air into the airways and lungs.
                
Although ventilator support can help premature infants survive, the machine's pressure might irritate and harm the babies' lungs. For this reason, doctors only recommend ventilator support when necessary.
                
High Levels of Oxygen
                
Newborns who have breathing problems might need oxygen therapy (oxygen given through nasal prongs, a mask, or a breathing tube). This treatment helps the infants' organs get enough oxygen to work well.
                
However, high levels of oxygen can inflame the lining of the lungs and injure the airways. Also, high levels of oxygen can slow lung development in premature infants.
                
Infections
                
Infections can inflame the lungs. As a result, the airways narrow, which makes it harder for premature infants to breathe. Lung infections also increase the babies' need for extra oxygen and breathing support.
                
Heredity
                
Studies show that heredity may play a role in causing BPD. More studies are needed to confirm this finding.
Question:
Who is at risk for Bronchopulmonary Dysplasia? ?

Answer:
The more premature an infant is and the lower his or her birth weight, the greater the risk of bronchopulmonary dysplasia (BPD).
                
Most infants who develop BPD are born more than 10 weeks before their due dates, weigh less than 2 pounds (about 1,000 grams) at birth, and have breathing problems. Infections that occur before or shortly after birth also can contribute to BPD.
                
The number of babies who have BPD is higher now than in the past. This is because of advances in care that help more premature infants survive.
                
Many babies who develop BPD are born with serious respiratory distress syndrome (RDS). However, some babies who have mild RDS or don't have RDS also develop BPD. These babies often have very low birth weights and one or more other conditions, such as patent ductus arteriosus (PDA) and sepsis.
                
PDA is a heart problem that occurs soon after birth in some babies. Sepsis is a serious bacterial infection in the bloodstream.
