hyperinflation

why do my lungs keep hyperinflating and is there anything i can do to stop it

[National Jewish Health]

Lung hyperventilation can often be the first sign of asthma and, with proper asthma therapy, is quite reversible.  In older individuals with a long history of smoking cigarettes, hyperinflation can be a sign of chronic obstructive pulmonary disease (COPD) and, in that circumstance, may not be entirely reversible.

If you are a young person less than 50 years old and especially if you are not a smoker, you should be checked for asthma and if you have it, get treated.  Arrange for spirometry, a simple breathing test that provides detailed information about how your lungs are working, and then don't worry about hyperinflation that has been mentioned on an x-ray report, if pulmonary function testing is normal.
