(by 1. Bronchoconstriction

2 .Mucus plugs

3 .Increased inflammation)

When airways bare exposed to various risk factors

A new environment may temporarily

improve asthma symptoms, but it will not cure asthma. After a few years in the new location, many persons become sensitized to the new environment, and the asthma symptoms return with the same or even greater intensity than before.
