The prevalence of EILO in adolescents and young adults appears to be in the range of 5–7% in northern Europe. Some, but not all studies report a higher female prevalence. Thus, in a study of 94 patients diagnosed using the CLE test, average age was ~15 years, and 68% were female. In athletic individuals EILO appears to be a highly prevalent cause of cough and wheeze and can co-exist with EIB. In one study, of almost 90 athletes, with unexplained respiratory symptoms, EILO was found to be present in approximately 30% of athletes, whilst EILO and EIB co-existed in one in ten. This condition can co-exist with other conditions, including severe asthma.
