What is Exercise Induced Laryngeal Obstruction (EILO), and why do I feel like my throat closes during exercise?

Exercise Induced Laryngeal Obstruction (EILO) is a condition where the structures of the throat temporarily narrow during high-intensity exercise, making it feel difficult to breathe in.

People often describe:

• Throat tightness
• Noisy breathing during exercise
• Sudden breathlessness at high intensity
• Feeling like the airway is “closing”

EILO is often mistaken for asthma, but it affects the upper airway rather than the lungs, and inhalers may not help.

With the right assessment and breathing strategies, many people can significantly improve symptoms and return to exercise with more confidence.
