When I was making my decision, after doing my research, I ruled out the sleeve because I already had severe reflux. My doctor asked me about the duodenal switch but I had already decided on the gastric bypass. It was the best decision for me. I never had any pain afterwards. I have never had "dumping syndrome" because I don't eat the things that cause it-high sugar! I have had what I call the most perfect surgery possible. I lost 114% of my excess weight and have maintained it for about 2 yrs now because I follow the guidelines I was given. This is a lifestyle change, not any easy way out! I will be 3 yrs post op in Oct. One of the best decisions I ever made! Good luck with your decision.
