Roux-en-Y gastric bypass
Roux-en-y is the leading choice of gastric bypass procedures. It is the most commonly performed weight loss surgery procedure in the U.S.
This surgery involves first creating a small vertical stomach pouch of less than one-ounce capacity. Then a bypass of most of the stomach and some of the small intestine is created.
The bypass helps you lose weight because:
- the stomach pouch is quite small (less than 1 ounce)
- the outlet from the pouch is quite small, so you must eat slowly
- after a bypass, patients tend to stay away from sweets
- interrupting the satiety center reduces hunger for eight to 10 months
