(Asma inducida por el ejercicio)
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.
