About the procedure
Laparoscopic Roux-en-Y Gastric Bypass causes weight loss by restricting the amount of food and reducing the absorption of the calories in the food you eat.
The stomach is divided into a small “pouch” in which food enters, and one large “remnant stomach” through which the food no longer passes. This “excluded” part of the stomach remains in the body and continues to produce helpful digestive juices, which meet the food further downstream. The upper, smaller “pouch” holds a smaller amount of food than before, and is connected directly to a portion of the small intestine, bypassing the larger part of the stomach created by the procedure.
