I had this Roux EN Y Bariatric surgery completed 22 years ago when I was 40. I lost from 400 lbs. to 210lbs and stayed there for about 6 weeks. Shortly there after I went up to 250lbs. and stayed at that weight until I reached age 55. I have gain up to 280 at this point and at age 62, I don't like this extra weight I have put back on. Is it possible to repeat the surgery again.
