Abstract

Exercise-induced laryngeal obstruction (EILO) describes laryngeal airflow obstruction during increased exercise [1], and is an important differential diagnosis for a variety of respiratory diseases, exercise-induced bronchoconstriction (EIB) being the most common [2]. The prevalence of EILO is reported to be as high as 27% among cross-country skiers [3], compared to 5–7% in the general young population [4, 5]. Breathing cold air may trigger airway obstruction in patients with EIB, and increase the test sensitivity [6].
