What is sleeve gastric bypass surgery?

Gastric sleeve bypass surgery involves surgical removal of up to 75% of the original stomach, with the leftover stomach flaps stapled together to create a new, smaller stomach in the shape of a bent shirt sleeve. The surgery is typically done laparoscopically and is a permanent surgery. The net effect is feeling full much earlier during a meal, thus reducing consumption. This surgery is indicated for the morbidly obese who have tried in good effort to lose weight multiple times, but cannot lose enough weight, and are having medical problems due to obesity.
