Asthma is a chronic disease of the airways that makes breathing difficult. With asthma, there is inflammation of the air passages that results in a temporary narrowing of the airways that carry oxygen to the lungs. This results in asthma symptoms, including coughing, wheezing, shortness of breath, and chest tightness. If it is severe, asthma can result in decreased activity and inability to talk. Some people refer to asthma as "bronchial asthma."
