What is Asthma?
Asthma is a disease that affects your lungs. It is one of the most common long-term diseases of children, but adults can have asthma, too. Asthma causes wheezing, breathlessness, chest tightness, and coughing at night or early in the morning. If you have asthma, you have it all the time, but you will have asthma attacks only when something bothers your lungs.
In most cases, we don’t know what causes asthma, and we don’t know how to cure it. We know that if someone in your family has asthma you are more likely to have it.
