I had a rny almost a year ago. You tube has an extensive gastric bypass community of bloggers. They were a huge help to me before and after surgery. Most hospitals have support programs in place, the process usually takes a few months just to get a surgery date. I was required to go through their pre-surgery program which included support meetings, a consult with a dietician,a physical, consult with an exercise trainer, a phycological evaluation and a bod pod which is a machine that measures your lean mass and fat and determines your bmi. This test is repeated at six months along with blood tests to determine your vitamin statis. I have fought my weight for years gaining and losing hundreds of pounds but always ending up higher than the weight I started at. I have had no major issues and am about 6 pounds away from my ideal weight. It is really hard in the beginning and it takes awhile to discover what works foodwise for you after the surgery. I am tremendously thankful for the surgery. It has changed my life.
