Asthma Asthma. Asthma is a chronic inflammatory disease of the airways. The disease manifests as recurrent attacks of wheezing, coughing and shortness of breath. During an asthma attack, the muscles surrounding the airways contract, limiting the amount of air supply to the lungs. The lack of sufficient air supply results in a choking sensation.

Asthma Asthma is a complex clinical syndrome of chronic airway inflammation characterized by recurrent, reversible, airway obstruction. Airway inflammation also leads to airway hyperreactivity, which causes airways to narrow in response to various stimuli. Asthma is a common chronic condition, affecting approximately 8%-10% of Americans, or an estimated 23 million Americans as of 2008. Asthma remains a leading cause of missed work days.
