Exercise-induced laryngeal obstruction (EILO) is a condition that causes paroxysmal wheezing and dyspnea during high-intensity exercise. It is a form of inducible laryngeal obstruction (ILO). The laryngeal obstruction is caused due to inappropriate adduction of the supraglottic structures and/or adduction of the vocal cords, which should open during inspiration. It has been described by various terms such as vocal cord dysfunction (VCD), paradoxical vocal cord motion (PVFM), and laryngomalacia. Recently, these terms have been unified. The diagnosis is confirmed by continuous laryngoscopy during exercise (CLE), but only a limited number of facilities can perform CLE.

This condition is often treated as exercise-induced asthma. Hopefully, the awareness about this disease will increase with further studies.
