My band slipped in November and my doctor emptied it. I went back in January and he put 3 cc's in, but no restriction. I went for an barium swallow and they said it has slipped. I am waiting to see the doctor to see what he will do. What is sleeve gastrectomy? I am thinking about gastric bypass instead. I have already gained 30 lbs back from November. Has anyone had bypass after banding?
