What is asthma?
Asthma is a chronic (long-term) lung disease. It affects your airways, the tubes that carry air in and out of your lungs. When you have asthma, your airways can become inflamed and narrowed. This can cause wheezing, coughing, and tightness in your chest. When these symptoms get worse than usual, it is called an asthma attack or flare-up.
What causes asthma?The exact cause of asthma is unknown. Genetics and your environment likely play a role in who gets asthma.
An asthma attack can happen when you are exposed to an asthma trigger. An asthma trigger is something that can set off or worsen your asthma symptoms. Different triggers can cause different types of asthma:
Asthma triggers may be different for each person and can change over time.
Who is at risk for asthma?Asthma affects people of all ages, but it often starts during childhood. Certain factors can raise your risk of having asthma:
The symptoms of asthma include:
These symptoms can range from mild to severe. You may have them every day or only once in a while.
When you are having an asthma attack, your symptoms get much worse. The attacks may come on gradually or suddenly. Sometimes they can be life-threatening. They are more common in people who have severe asthma. If you are having asthma attacks, you may need a change in your treatment.
How is asthma diagnosed?Your health care provider may use many tools to diagnose asthma:
If you have asthma, you will work with your health care provider to create a treatment plan. The plan will include ways to manage your asthma symptoms and prevent asthma attacks. It will include:
If you have a severe attack and the short-term relief medicines do not work, you will need emergency care.
Your provider may adjust your treatment until asthma symptoms are controlled.
Sometimes asthma is severe and cannot be controlled with other treatments. If you are an adult with uncontrolled asthma, in some cases your provider might suggest bronchial thermoplasty. This is a procedure that uses heat to shrink the smooth muscle in the lungs. Shrinking the muscle reduces your airway's ability to tighten and allows you to breathe more easily. The procedure has some risks, so it's important to discuss them with your provider.
What is alpha-1 antitrypsin deficiency (AAT deficiency)?
Alpha-1 antitrypsin deficiency (AAT deficiency, or AATD) is an inherited condition that raises your risk for lung and liver disease. If you have this condition, your body doesn't make enough alpha-1 antitrypsin (AAT).
AAT is made by your liver. It helps protect your lungs from inflammation and irritating substances you might breathe in, such as smoke. If your liver doesn't make enough AAT, your lungs may be more easily damaged from smoking, pollution, or dust from the environment. This can lead to a serious lung condition called chronic obstructive pulmonary disease (COPD). AAT deficiency may also cause a liver disease called cirrhosis. This is more common in children who have AAT deficiency.
What causes alpha-1 antitrypsin deficiency (AAT deficiency)?AAT deficiency is a genetic disorder. That means it's caused by changes in your genes, which may also be called gene variants or mutations.
Your genes carry information that controls what you look like and how your body works. AAT deficiency is caused by changes in the SERPINA1 gene, which carries instructions for making the AAT protein. These gene changes are inherited from your parents, so AAT deficiency tends to run in families:
There are a few gene changes that cause AAT deficiency. These gene changes can:
Some people who have AAT deficiency do not have any symptoms. For those who do, symptoms usually appear in people between 20 and 50 years old. These symptoms may include:
Some people who have AAT deficiency may have liver damage. Signs of liver damage include jaundice (a condition that causes your skin and eyes to turn yellow) and swelling in your legs.
Rarely, AAT deficiency can cause skin problems, such as painful lumps or patches.
How is alpha-1 antitrypsin deficiency (AAT deficiency) diagnosed?Your health care provider may test you for AAT deficiency if you have:
AAT deficiency in babies often affects the liver. Your baby may need AAT testing if he or she has signs of liver disease such as jaundice or abnormal liver enzyme tests.
A blood test can check the level of AAT protein in your blood. If the level is lower than normal, it is likely that you have AAT deficiency.
A genetic test is the most certain way to check for AAT deficiency and should be done to confirm the results of the blood test. There are two types of genetic tests:
If your lungs are affected, you may also have lung function tests to see how well your lungs are working.
What are the treatments for alpha-1 antitrypsin deficiency (AAT deficiency)?There is no cure for AAT deficiency, but there are treatments to help with the symptoms and slow the lung damage it causes. Treatment options may include:
To help prevent or delay lung damage, it is important to quit smoking (if you smoke) and avoid secondhand smoke, dust, and air pollution. Ask your provider If you need to stop drinking alcohol.
What is atrial fibrillation (AFib)?
Atrial fibrillation, also known as AFib or AF, is one of the most common types of arrhythmias. Arrhythmias are problems with the rate or rhythm of your heartbeat. They can cause your heart to beat too slowly, too fast, or in an irregular way.
If you have AFib, your heart beats irregularly and sometimes much faster than normal. Also, your heart's upper and lower chambers do not work together as they should. When this happens, the lower chambers do not fill completely or pump enough blood to your lungs and body. This can cause symptoms such as dizziness, fatigue, and a pounding heartbeat.
AFib may happen in brief episodes, or it may be a permanent condition. It's very important to treat it, since AFib can put you at risk for stroke and other heart conditions.
What causes atrial fibrillation (AFib)?AFib is most often caused by changes to the heart's tissue or the electrical signaling that helps the heartbeat. These changes can happen due to different conditions and factors, such as high blood pressure, coronary artery disease, congenital heart defects, infections, and aging. Sometimes the cause is unknown.
Who is more likely to develop atrial fibrillation (AFib)?Anyone can develop AFib, but there are certain things that raise your risk for it:
Some people who have AFib don't have any symptoms and don't know they have it. If you do have symptoms, you may only notice them once in a while. Or you may have symptoms that are more frequent. And in some cases, the symptoms might be severe. If you have heart disease, you are more likely to notice your symptoms. And those symptoms could get worse if your heart disease gets worse.
The symptoms of AFib can include:
If AFib is not treated, it can lead to serious health problems (complications) such as:
To help prevent these problems, it's important to contact your health care provider if you are having symptoms. If you do have AFib, the sooner you are diagnosed and treated, the better.
How is atrial fibrillation (AFib) diagnosed?To find out if you have AFib, your provider:
The treatments for AFib may include:
There are steps you can take to help lower your risk of atrial fibrillation, such as:

Coughing is a reflex that keeps your throat and airways clear. Although it can be annoying, coughing helps your body heal or protect itself. Coughs can be either acute or chronic. Acute coughs begin suddenly and usually last no more than 2 to 3 weeks. Acute coughs are the kind you most often get with a cold, flu, or acute bronchitis. Chronic coughs last longer than 2 to 3 weeks. Causes of chronic cough include:
Water can help ease your cough - whether you drink it or add it to the air with a steamy shower or vaporizer. If you have a cold or the flu, antihistamines may work better than non-prescription cough medicines. Children under four should not have cough medicine. For children over four, use caution and read labels carefully.
What are disabilities?
A disability is any condition of your body or mind that makes it more difficult for you to do one or more major life activities and interact with the world around you.
There are many types of disabilities, such as those that can affect your:
More than 1 in 4 adults in the United States have some type of disability. Even though they all have disabilities, they can have a wide range of needs. For example, even people who have same type of disability can be affected in very different ways. Also, some disabilities are "visible" (easy to see), for example when someone is in a wheelchair. But other disabilities are "invisible" (hidden or not easy to see), such as problems with hearing, thinking, or learning.
What causes disabilities?Disabilities can have different causes. Some disabilities are present at birth, while others may happen later in life.
Causes of disabilities that are present at birth can include:
Causes of disabilities that happen later in life can include:
Having a disability does not mean a person cannot be healthy. In fact, many people with disabilities report that their health as good or better. But they may have or be at risk of health problems related to their disability, called "secondary conditions." These conditions may include:
Many of these conditions can be prevented, and there are treatments for them. It's also important for people with disabilities to get health care that meets their needs as a whole person, not just as a person with a disability.
How can people with disabilities get and stay healthy?Just like for people who don't have a disability, having a healthy lifestyle is important for people who do have a disability. A healthy lifestyle includes:
Managing a disability can sometimes be challenging. There are resources that can help:
