What is a sleeve gastrectomy?

I've decided to have a gastric sleeve done, which is a relatively new technique. A lot of people have heard of lap bands but not as many people know about the gastric sleeve. Basically it involves cutting out 3/4s of your stomach to create a small tube instead. From then on, you cant eat anywhere near the volume that you once could, which obviously is how the weight loss comes about.

The other cool thing about it is that it helps you feel less hungry. I don't understand the full science of it but there is a hormone/thingy called ghrelin which is basically your hunger impulse, and the removing of a big chunk of the stomach significantly reduce the amount of ghrelin, thereby making you feel less hungry.
