HOW A GASTRIC BYPASS WORKS
During the Gastric Bypass procedure, the surgeon creates a stomach pouch that significantly reduces overall stomach size and the amount of food it can hold.
- The pouch is surgically attached to the middle of the small intestine, thereby bypassing the rest of the stomach and the upper portion of the small intestine.
- The smaller stomach size helps patients feel full more quickly, which reduces food intake.
- Bypassing part of the intestine limits calorie absorption.
- Gastric bypass also produces profound physiologic and metabolic changes in many organs as a result of surgical anatomic manipulation.41
