Either you have the band, sleeve or bypass, they are all ONLY tools for weight loss. NONE of them are a magic wand and will solve all your problems. I had the bypass 7 weeks ago and I'm over the moon with the results. Whatever option you choose,my only advice would be Do Your Research, and use all the resources available to you. Ask as many questions as you can, and don't dismiss others bad experiences thinking "it will never happen to me". Cause you just never know. this is a major commitment and you should go in with your eyes open. There are sacrifices that will need to be made regardless which option you choose. WLS is a very individual and personal journey and works differently for everyone, I have found my GP to be outstanding and the team at the hospital can't do enough for me, I even had a call from them last week just to check up on me and see how I am doing.
Whatever your decision i wish you all the luck in the world.
