Asthma

A chronic disease that affects the airways. In people with asthma, the airways are inflamed and sensitive to allergens or irritants. During an asthma attack, the airways get narrower, and less air flows to the lungs, causing symptoms like wheezing, coughing, chest tightness, and difficulty breathing. Asthma can be managed by avoiding things that bring on asthma symptoms and by taking medication to control symptoms and prevent attacks.
