Asthma is a chronic lung condition that causes inflammation and swelling of the airways, sensitivity to things that make swelling worse, and decreased airflow in the lungs. In the United States, asthma affects about 25 million people. There is no cure for asthma, but you can learn to manage it so you can maintain a normal activity level and minimize the need for emergency treatment.
