What Is Asthma?
Asthma is a chronic lung disorder that can make breathing difficult. It features narrow, inflamed airways (bronchial tubes). "Asthma" is an ancient Greek word meaning "short breath," and as the name implies, it can leave you gasping for air. One of the telltale signs of an asthma attacks is wheezing with difficulty breathing. Other asthma symptoms include chest tightness, coughing, and shortness of breath.
When the breathing tubes of the lungs become chronically inflamed, they can become sensitive to inhaled environmental allergens and irritants that can trigger asthma. These environmental triggers include pollen, pollution, and tobacco smoke. Exercise can also be an asthma trigger for some.
