Don't worry bout it Katie the consultant and the bariatric lead nurse will suggest which procedure they think mat suit you and your life style best. They take into account your physical daily life and mental state and look at wether you have a sweet tooth, graze all day, binge etc. I always thought I would have a band the doc suggested a bypass and the nurse but they wouldnt force me to have it, however after much discussion my hubby and I both thought it best to go along with what the consultant thought was best. So bypass it was and now I am 9 months post op have lost just over 6 stone since op and lost almost 2 before the op between July n August with the helpof the pre op diet as well so just about 8 stone since last July which is marvellous even though I sya it myself, take the medical professional advice thye know how the body workd in general and give good solid advice, be prepared to come out with a different view to what you went in with. The bypass was the 1 thing my husband did not want me to have. But he changed his mind and supported me all the way, he is very proud of me as are my family and close friends, and last but not least I AM PROUD OF ME. good luck with your journey just keep an open mind xx
