What is Asthma?, ASTHMA
Asthma is a chronic condition that involves inflammation and narrowing of the bronchial tubes, or airways, resulting in breathing difficulty.

When inflamed the airways become highly sensitive and react adversely to certain triggers that induce the onset of an asthmatic attack.

Asthma is the most chronic childhood disease affecting 1 in 15 children. Its incidence, among adults too, has increased dramatically in the recent years.
