Some people have asthma symptoms (such as coughing, wheezing, or trouble breathing) only when they're doing sports or being active. Being active may be the only cause of their breathing trouble, or it can be just one trigger that causes problems. Kids who have this kind of asthma need to see a doctor and find out how to treat it. But once they do, they usually can be active and do sports like anyone else. In fact, more than 10% of Olympic athletes have exercise-induced asthma that they've learned to control.
