I had my consultation with my surgeon last Friday. I'm 21 and he actually recommended the bypass for me because of the amount of weight I need to lose. I'm weighed in at 309 the day of my consult. I also have a heart murmur that I've had since I was a child. I don't need to get any cardio testing done.
I'm personally going with the bypass. It has its cons, but I would rather deal with them and lose the weight that I want to lose. I'll have to take Vitamins for the rest of my life, may have issues with dumping and whatnot but it's worth it to me. Keep in touch and good luck!
