Hi. This is something I am also looking into. I have only just secured my funding after a 2 year battle, but when I had my first hospital appointment in 2009 I was told that I should have the bypass. A good friend of mine is further along than me and she will get her op date in November, but at her last appointment she was told to decide between the bypass or sleeve by her next visit.
She was adamant she was having the bypass, but now after researching both she is more drawn to the sleeve. She states her reasons for this is that she does not want to take 'artificial' vitamins for the rest of her life, she wants to be able to eat and drink at the same time, the operation is shorter, she does not have type 2 diabetes or heart problems so bypass is not really her last resort and also if the sleeve does not work she could have the bypass later. She feels the bypass is final and will restrict her more socially than the sleeve.
I do think she has raised some good points and has made me think about what would be also best for me, but if anyone has any feedback it would be much appreciated. I am waiting for my appointment to go back and start the process again at the hospital so I have plenty if time to look at my options.
Thanks
