Several months ago, reports published that many post bypass Sx people have benign pancreatic tumors causing
hypoglycemia. Seems, though, no one yet sure if those tumors should be removed -- it corrects hyppoglycemia, but no one knows how long it will be before more grow. My doctors feel it best to try to treat the unstable insulin, but the endocrinologist admits he is going through uncharted territory and merely "guessing" what to do. I was put on Metformin (Glucophage) 500 mg.
