Hyperinflated lungs: What does it mean?
I recently saw my doctor for a persistent cough, and he ordered a chest X-ray. The radiologist noted slight hyperinflation of the lungs. What does this mean? Could it be emphysema?

Answer
Hyperinflation of the lungs as seen on a chest X-ray isn't a specific diagnosis. It is a subjective interpretation that may mean nothing. However, your concern is understandable. Hyperinflated lungs can be associated with a number of serious lung conditions, such as emphysema, asthma or lung cancer.
The only way to know whether you have emphysema is to do a lung (pulmonary) function test. If your lung function is normal, it is unlikely you have emphysema. If it is abnormal, you should see a lung specialist to determine whether treatment is appropriate.
