I initially asked my GP for a band but the surgeon thought a bypass would be better for my Type 2 diabetes. Now that I've researched it I am completely happy with the decision. Also. after about 2 years, when the internal scars have softened and stretched, you eat more or less normally (albeit smaller amounts) and the body absorbs only 30% whereas with a band you have restriction throughout your weight loss and will always have to take tiny mouthfuls and chew for England. The operation for a bypass is invasive and alters your 'plumbing' permanently. A band operation is always keyhole, is a shorter operation and completely reversible. Once a bypass has been performed, that's it. No other maintenence is required other than taking vitamins for the rest of your life whereas with a band you need to maintain it with fills and there are things that can go wrong at a later date such as slippage, leaking, or problems with the port. These things are rare but can happen. Once you have done lots of research one of the options will jump out at you as being the right one for you. I've never known anyone regret their decision whether bypass or band. Good luck, Zxx
