I am 56. Had mine in May @55' turned 56 in August. Have lost 80 lbs so far. And am loving life. As far as weight loss is concerned. After you have surgery, please make sure that you keep up with you supplements. I know 3 people that have had heart attacks and one of them actually died because they were so anemic and very little iron Keep on your doctor. Would I do it again? In a minute.
