Can asthma reduce your height?

Probably not: Though there has been an association between young children using chronic inhaled steroids and achieving their max height, that association only accounts for a very small height reduction (maybe 1-2 cm). If this is not the scenario you are in, the answer is no.

Rarely: In kids that have ICU quality asthma & take oral steroids to survive/recover, there is evidence that long term use will reduce finalheight.These kids are often in the ICU before they are a year of age and hospitalized repeatedly.This is a fraction (<3%) of those with asthma.For your average asthma patient that follows a standard treatment plan, this is not a problem.
