Hi I'm 50 years old and have a Bmi of 52. I am struggling with the decision whether to have surgery. I have lost 100+ lbs a few times in the past. When I am losing, I am pretty disciplined and do well with weight loss. Then something switches and it all goes to crap and I end up gaining all the weight back and then some. I am so fearful that I will do well with the surgery but something will switch in my brain, and the weight will all come back on. Is there any reason that the surgery will change this pattern? i really want the surgery, but the fear of regain is holding me back. I guess I am an all or nothing person. Anybody relate or any advice? The mental part of this is frightening.
