I had gastric bypass surgery (Open RNY) in April 2004. The surgery saved my life.
I wouldn't necessarily recommend the surgery to someone else. Its a very personal decision. Its a risky surgery. Its life changing, and not something that should be entered into lightly. Medical testing should be done, therapy should be obtained, a support group should be attended, and lots and lots of research should be done on the surgery itself and the surgeons you are thinking about using.
Surgery is not a quick fix. If you are not ready to change your life forever, surgery is not for you. The surgery is a tool to help you lose weight initially. Its up to you to continue to take the weight off, and maintain it once you reach your target weight. The stomach pouch CAN and does stretch. Anyone contemplating this surgery for anything other than health reasons will be extremely disappointed. Weight is often a symptom of something else, and I've found that as the weight comes off, those things the weight was hiding begin to surface. You become very vulnerable.
Like I said in the beginning, this surgery saved my life. I started at 288lbs, a size 26/28. I am now 136lbs, size 6. My BMI went from a very unhealthy 46.5 to 22.something. It took me 18 months to loose the weight, and I've been maintaining for a year now. Its been a long journey, some of it very difficult, especially from the mental/emotional side. I've been blessed with a very loving and supportive husband. I've been blessed with wonderful friends. I can run with my children again. Not that it was in trouble before, but I have a better, closer relationship with my husband. I found myself again. For that, I am forever greatful. The looks are just a bonus.
