If you have had a gastric bypass and you lost a large amount of weight, and now you are gaining a lot of that weight back, it is possible that your stomach has stretched or reopened and you are now able to eat more food, or you are somehow taking in enough calories even in small amounts to gain weight. Either way, the answer right now is not Plastic Surgery, the answer is to either call your General Surgeon who did your bypass or call your registered dietician and determine why you are gaining the weight back and more importantly, how to stop the weight gain and get back to weight loss. Insurance will not cover your tummy tuck. As the other doctors stated, a panniculectomy MAY be covered by insurance but that is not a cosmetic surgery, it is simply cutting off extra skin that hangs well below the abdomen, often covering your groin or even your thighs.You should NOT entertain ANY type of body contouring surgery until your weight is back to being stable for at least 6 months. Best of luck!
