vertical sleeve to DS

Who was your surgeon? In his/her hands it might indeed be very risky, but a lot LESS risky in the hands of a surgeon who does it all the time.

You sound like you have the same kind of problem I had with an impaired/nonexistent satiety. The intestinal changes of the DS are what fix this, or so it seems. It's not just a matter of the belly being full of food.

Have you done a scope or a scan to see if your sleeve was properly made?
