Can children outgrow asthma?
  About half of the children with very mild and infrequent symptoms appear to outgrow asthma with time. For most of the other children with asthma, their airways can handle inflammation and irritants more effectively as they grow older and the frequency of attacks and the severity of symptoms may get less.

Some of them may also find that asthma recurs with varying severity from their twenties onwards. It is difficult to predict accurately whether a child will have fewer asthma attacks as they grow up.

However, it is important to understand that effective treatment will reduce asthma symptoms, improve quality of life and ensure good health outcomes.
