I had the Roux-en-Y 10 years ago and I would do it again in a second if I had to!
I went into surgery weighing about 480. I lost 70# the first month and plateaued at 240. I gained back about 10-15% which is fairly normal. I could lose more if i wanted but I am happy here.
I had my pandelectomy about 5 years ago.
The most it hurt was that day. After that the pain was FAR less. I also didnt realize how unhealthy I was.
If you are severly overweight with no chance of losing weight via traditional diets, this is the way. Dont let anyone tell you its a cop out, because IT IS NOT!
