Roux-en-Y Gastric Bypass (Open Surgery Method)


This surgery makes your stomach smaller. That helps you eat less and lose weight when diet and exercise don't work. It can help you avoid serious health problems linked to obesity.


To begin, you're put to sleep. The surgeon makes one or more incisions to reach your stomach and your small intestine.

Modifying your stomach

The surgeon carefully divides your stomach into two parts. The small upper pouch will digest your food. The larger lower section won't be used for food at all. Next, the small intestine is divided. The lower part is pulled up and attached to the stomach's food pouch. This is the new pathway for your food. Then, the other part of your small intestine is reconnected. This lets digestive juices flow from the bypassed part of your stomach into your small intestine.

End of procedure

After the surgery, you're watched in a recovery room as you wake up. You'll need to follow your doctor's instructions carefully for a safe recovery.
