Some people have asthma symptoms (such as coughing, wheezing, or trouble breathing) only when they're playing sports or being active. This type of asthma is known as exercise-induced asthma. Being active may be the only cause of their breathing trouble, or it can be just one trigger. People with exercise-induced asthma need to see a doctor. But once they get treatment, 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.
