Mini-Gastric Bypass Surgery (OAGB)

Mini gastric bypass surgery (MGB or OAGB) is a weight loss surgery that can be revised. It is very similar to the traditional Gastric Bypass but only has one connection to the small intestine (instead of 2). Instead of a small pouch like with the gastric sleeve, the mini gastric bypass surgery procedure creates a narrow tube-like pouch that holds approximately 1-2 ounces, restricting the amount of food that can be taken in at one time. The small intestine is then attached or looped to the new pouch approximately six to seven feet from its starting point. This placement bypasses the part of the intestines that allows for less nutrients, calories, and fats to be absorbed by the body, causing weight loss.
