What is asthma?

Asthma or bronchial asthma is an inflammatory disease of the airways. It is associated with increased sensitivity of the bronchial tubes to various stimuli. Typical symptoms include shortness of breath (often seizure-like and occurring mainly at night and in the early morning), a whistling sound when breathing (wheezing), a feeling of tightness in the chest, and coughing.^{[14], [15], [16]}
