Hello, this question to me is not too personal. I tried figuring out myself how much weight I would loose after surgery.
I had the RNY done on Sep. 16, 2009 which was 6 monthes and 2 days ago. I am 4'11" and my presurgery weight was 234. I am now down 79 pounds and weigh in at 155. The change is so dramatic and flew by for me.
I wish you all the best and will keep you in my prayers on your surgery date. Please feel free to email anytime you have questions or just wanna talk. You can also friend request me on the OH site.
