What is asthma?

Also known as: allergic asthma, occupational asthma, exercise-induced bronchoconstriction (EIB), exercise-induced asthma (EIA).

Asthma is a breathing disorder that involves the airways becoming inflamed. This causes the muscles around the airways to tighten and swell and cause trouble breathing. It’s usually the result of some form of “trigger” that causes the asthma episode.
