Exercise-induced laryngeal obstruction : diagnosis and management

Abstract

Exercise-induced laryngeal obstruction (EILO) is a condition characterized by temporary narrowing or closure of the larynx during physical activity, in particular during intense physical exertion. It generally affects teenagers and young adults and is often misdiagnosed as exercise-induced asthma. Symptoms include dyspnea, wheezing and a feeling of throat tightness during exercise. The aim of this article is to review this often underrecognized condition, its diagnosis and its management.
