I chose gastric bypass because in my mind it is what I wanted because I felt it would help me not only be able to not eat as much, but wouldn't let me absorb some of what I do eat as well. When I went to the doctor and to suggest the gastric bypass, he said that gastric bypass is all he does as he found it is the only thing he finds that works long term. It probably was his own belief, but I was all for it. I went further and asked how much intestines will be by passed. I didn't get as much as I'd prefer, but hey.
