Asthma and weight loss

My pulmonary doctor told me that since I was carrying too much weight on my chest that it couldn't expand properly and that is why my peak flow is quite low and I am quite short of breath.

Is there anybody out there that as been banded awhile and had this particular circumstance? I really had a asthma problem after the anesthesia - had to start taking breathing treatments for a couple of weeks.

How long did it take to see an improvement in your asthma?

Thanks,

Kerry
