Find out how a gastric banding bypass surgery could potentially help you lose weight



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

Gastric bypass patients report an early sense of fullness while eating and being satiated sooner. This reduces the desire to eat more.

Gastric bypass procedure

This method can be performed through an open procedure or laparoscopic (minimally invasive) procedure. Most surgeons prefer the laparoscopic approach because it makes small incisions usually resulting in faster recoveries and less pain than open surgeries.
