Repeated preschool wheeze may set stage for long-term damage in lung function

Children who wheeze are at risk of developing damage that will affect their lung function by the age of 6 years, according to researchers. These appear to be persistent, even if asthma symptoms seem to disappear at least temporarily by school age in several cases. Children with recurrent symptoms that are severe enough to warrant a visit to the emergency department are particularly at risk of seeing their lung function affected.
