Like "Wow that is really a tough decision to make. You did not state what type of diabets you have. Once I got a meal plan from a dietician and started following it I lost some weight without even trying. I have known several people who had both the bands and intestional by-pass, none were diabetic. All had many illnesses after the surgery for years. One gained back all he had lost on the by pass. Along with consulting the surgeon I highly recommend a consultation with an Endocrinologist. They specialize in diabetes and might be able to give you some valuable information on what they have seen in patients who have had this done. Good luck with your decision, Mary"
