Asthma in children

Exercise induced laryngeal obstruction (EILO)

Does your child have breathing problems during exercise?

A condition called exercise induced laryngeal obstruction (EILO) is sometimes misdiagnosed as asthma. It’s most common in adolescents who wheeze when they exercise.  The wheezing noise is different to the wheeze found in asthma in two ways: the noise in EILO can be very loud and it comes on during breathing in.

EILO can also co-exist with asthma so if your child is still getting breathing problems despite asthma being treated, then this might be present as well.
