Been there. Remember with a bypass you are eating and absorbing less, much like your starving slightly. This low calorie absorption makes you lose weight. If you are say absorbing 900 calories and you eat enough to absorb 1200 calories you will gain weight. Your body adjusted to be more efficient on 900 calories though a little stressed. More calories make your body grab it and store it.
combine that with the stretching of the organ bypassed and you have weight gain. I find upping my excercise and drinking my diet for a couple of weeks brings me back down but bypass doesn't end your problems and its not your fault if you eat a healthy amount of food. In a few months your body will adapt again but in the meantime you will gain. Doctors don't tell you that part.View Thread
