Asthma is a common disease of the lungs. There is no cure for asthma, but it can be controlled. With treatment, a person with asthma can live an active life. If left untreated, asthma can severely impact a person’s life.

Asthma affects the airways in the lungs. People with asthma have airways that are extra sensitive to different things in the environment such as cigarette smoke, dust mites and mold.  When people with asthma breathe in these things, their airways become inflamed and swollen. Air can’t get through the airways and it is harder to breathe.

Asthma is a chronic disease. It is a lifelong condition that can cause permanent damage if it is not treated properly. Asthma is not contagious, but it often runs in families that have a history of asthma and allergies. Asthma is the most common chronic disease of childhood and the number one reason why children miss school.
