Yeah, if you're considering gastric bypass, you want to really think about it. I've read that after five years, it's very common to start having problems, even if you didn't before. My bf's mother had it. I don't know if it's true, but I've also heard that you produce some very nasty odors when you use the bathroom after gastric bypass. A shrink once suggested it to me, as if it were nothing. Another shrink suggested a hysterectomy in the same manner, because I don't want children. We're talking about changing the way your body works, so you really want to educate yourself before you jump into that. And you don't lose weight easily...besides the stuff Sky mentioned, it doesn't change your appetite. You still crave the food. It forces you to change the way you eat, though, but it doesn't always work as well as you hope (see Roseanne, the actress/comedienne).
