Sad news.
Yeah, I think a lot of people see this as a sort of quick-fix for weight loss, especially with the way it's portrayed in the media with celebs like Sharon Osborne getting it done, like it's just some sort of routine surgery.
But it's a drastic measure and sounds very risky to me. I'd be determined to lose the weight through strict dieting and exercise, rather than risk the surgery. Sorry to hear of your loss.
