Exercise-induced asthma.

Abstract

Exercise-induced asthma (EIA) is a common condition that can impede physical activity, particularly for children, adolescents, and young adults. A detailed patient history can help the physician identify subtle EIA clues such as fatigue or poorer performance than training would predict. A careful physical exam can help rule out conditions that mimic EIA such as respiratory infections or cardiac conditions. Pulmonary function testing is often useful for assessing severity and establishing a baseline for assessing treatment efficacy. Treatment options include nonpharmacologic measures that address the exercise environment and warm-up routines. Several medication options and combinations can help patients avoid symptoms and participate fully in fitness and sports activities.
