Asthma is a chronic (or lifelong) disease that can be serious—even life-threatening. There is no cure for asthma. The good news is that with proper management, you or your loved one with asthma can live a normal, healthy life.
What Is Asthma?
Asthma is a chronic lung disease that makes it harder to move air in and out of your lungs. It can start at any age. Understanding can help put you on the right path to managing asthma.
More than 25 million Americans have asthma, including 5.5 million children. It causes millions of lost school and workdays every year and billions in healthcare costs. Learn more about asthma trends and disease burden in our Asthma Trends Brief.
