It more often affects women between the ages of 20 and 40. There are a battery of tests to be performed in a effort to diagnose some with it. Most importantly Bronchoscopy. Its where they run a camera down thru your bronchial tubes to look for abnormalities. Lots of symptoms. Including fatigue, loss of appetitie, sleeplessness, PAIN.
