What is asthma?

Asthma is a chronic lung condition in which the bronchial tubes narrow and swell and produce extra mucus. The most common symptoms of asthma are coughing, wheezing, chest tightness, and shortness of breath. For some people, asthma is a minor nuisance, while for others it can interfere with daily activities. In 10-15% of patients who have severe asthma, asthma may be severe enough to require hospitalization, and in rare instances, be life-threatening.

Up to 25% of young children may wheeze with colds or flus, and about 7-10% of children develop chronic asthma. In adults, the numbers are lower, with 3-5% having chronic asthma.
