Exercise-induced laryngeal obstruction

Exercise-induced laryngeal obstruction (EILO) is a transient, reversible narrowing of the larynx that occurs during high intensity exercise. This acts to impair airflow and cause shortness of breath, stridor and often discomfort in the throat and upper chest. EILO is a very common cause of breathing difficulties in young athletic individuals but is often misdiagnosed as asthma or exercise-induced bronchoconstriction.
