Question 1

What is EILO?

Accepted Answer

Exercise-induced laryngeal obstruction (EILO) is a condition where the structures of the larynx narrow or close during exercise, limiting airflow and creating breathing restriction. Unlike asthma, it affects the upper airway and symptoms typically resolve quickly after stopping exercise.

Question 2

How is EILO different from asthma?

Accepted Answer

EILO restricts inhalation (breathing in), while asthma causes difficulty exhaling and wheezing. EILO symptoms resolve rapidly after stopping exercise, whereas asthma often persists. Rescue inhalers provide little relief for EILO because it is an upper airway condition, not a lower airway condition.

Question 3

Who does EILO affect?

Accepted Answer

EILO affects 5–8% of the general adolescent population and is 30–40% more common in athletes. It is 3x more common in females, particularly those in competitive sports environments. It commonly affects runners, swimmers, soccer, lacrosse, and field sport athletes.

Question 4

Does Functional Airway Lab offer virtual sessions?

Accepted Answer

Yes. Functional Airway Lab offers both in-person sessions in Ventura, CA and virtual telehealth sessions for athletes anywhere.
