Laparoscopic Gastric Bypass
A small stomach pouch is created by dividing the top of the stomach from the rest of the stomach.
A segment of the small intestine is brought up and hooked up to the stomach pouch.
The food bypasses the stomach and major portion of intestine.
How does Gastric Bypass Surgery Work?
The small stomach pouch reduces the amount of food intake.
Decreased absorption of calories due to intestinal bypass.
Changes in gut hormones that promote satiety and suppress hunger.
