A friend of mine had gastric bypass a couple years ago... yes, it is a very dangerous surgery (I think they offer a laporoscopic version now, but still dangerous...) Her scar was pretty big... but she came through it okay, it was a struggle for her to get use to the new eating habits... you truly cannot eat very much at all, I don't know how people do it!! Her biggest problem was that she lost alot of weight but her skin then sagged horribly... she was very young and ended up having to have skin excissions and a tummy tuck, so yet more surgery. I know that between all of her surgeries, it cost her upwards of $15K, not sure what insurance covered, etc. She lost 120 lbs. Good luck to you!
