Asthma Management Initiative

Asthma is a chronic lung condition that causes inflammation of the airways (breathing tubes). Inflammation means the airways are swollen and produce mucus. During an asthma flare-up, inflammation increases and the muscles around the airways tighten up, making them narrower. The swelling, mucus and tightness of the airways makes it hard for air to move in and out and causes symptoms such as coughing, wheezing, and shortness of breath.
