I am wanting to get the Gastric Bypass surgery but the DR I saw told me that there is a potential risk of an ulcer because I am an ex-smoker. I quit about 7yrs ago and was wondering what is the risk % of actually getting an ulcer with the bypass surgery for a 7yr ex-smoker. the Dr I saw wouldnt give me a % just said there was a risk of life threatening ulcers because its only been 7yrs. Thank You
