Asthma is a non-communicable chronic disease that affects the airways in the lungs. It causes repeated episodes of wheezing, breathlessness, chest. tightness, and nighttime or early-morning coughing. During an asthma attack patients may experience bronchospasm (a tightening of the muscles around the airways), inflammation of the lining of the airways, and/or increased mucus production that may clog airways. Asthma may be intermittent, persistent, allergic, non-allergic, pediatric, adult-onset, exercise-induced, occupational, or can exist alongside Chronic Obstructive Pulmonary Disease (COPD), called Asthma-COPD Overlap Syndrome (ACOS). As of 2020, asthma currently impacts an estimated 25.3 million Americans, resulting 12.6 deaths per 1,000,000.
