I chose Gastric Bypass 18 years ago because of the restriction and the malabsorption. I needed the restriction because I was a binge eater. I wanted the malabsorption because I always felt my system was over achieving. Also the prospect of a 50% chance of dumping was a plus for me as I could see sugar being a problem.
Fortunately, I do dump on sugar and fats, so I learned very early to stay on the straight and narrow.
Good luck,
Tek
