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
