Asthma is a chronic lung disorder in which inflammation causes swelling and narrowing of the airways, creating breathing difficulties that may range from mild to life threatening. Symptoms include shortness of breath, coughing, wheezing, and chest tightness (American College of Allergy, Asthma & Immunology.
