I had 1/3 of my stomach removed and a Rue-Y procedure done due to birth complications and a contaminated endoscopy at the age of 42. So, basically, I have had gastric bypass surgery for reasons other than weight loss. I suffer from a lot of gas (belching-flatulence) and can't seem to get a long term control of it. Probiotics helped for a while. I try to minimize gas producing foods and eat fiber. This seems to minimize some of the problem.
