As a child, before I was out-of-shape, I was diagnosed with "exercised-induced asthma." Is that a lifelong diagnosis? Or do youngsters tend to grow out of it?

I continue to take my Albuterol inhaler and daily puffs from my Advair as the "exercised-induced asthma" diagnosis has carried over into my adulthood. This is because I continue to get a tight-chest and consistent wheezing/coughing during and after any period of exercise. But... are these caused by "exercised-induced asthma" or could it be that I'm simply out of shape (admittingly, I could lose 15 pounds)? Or could it be a combo?

How do you know if you have exercise-induced asthma for sure?

Do pulmonologists consider exercise-induced or "seasonal" asthma a legitimate diagnosis?
