Hi, (sorry for my english)..6 years ago I had the sleeve , I lost 20 kgs. (I wasn't very overweight, but I wanted to be thin). I kept my weight for 3-4 years, until I had to stop making excersice ( I ran marathons,ironmans, play tennis, etc), because an injury on my neck. So the last year I regain half of the weight I lost at the begining of my sleeve. To make it short I went to the doctor, he said I didn't need to lose weight but if I really wanted he would make my stomach as small as the first time (it is called "la remanga"). "the sleeve again".. It was a total disaster, whatever I eat I vomit it, even the water I drank I couldn't keep it in my stomach. So the doctor had to make me an emergency bypass in January (6 days after "la remanga"). So I had 2 operations. I lost 10 kgs. I am very thin again, but it was really scary and its been difficult in many ways. Between the sleeve and the bypass, I would choose the sleeve by far (for many reasons). Hopefully my experience can help you in some way.
