What is Gastric Bypass Surgery?

The Gastric Bypass, or Roux-en-Y Gastric Bypass, is the oldest and most commonly performed bariatric surgery procedure. The gastric bypass weight loss surgery helps patients lose weight by restricting the amount of food a patient can consume, and by creating a malabsorptive effect.

How does it work?

First, a small stomach pouch is created to restrict food intake. Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the lower stomach, the duodenum (the first segment of the small intestine), and the first portion of the jejunum (the second segment of the small intestine). The bypass reduces the amount of calories and nutrients the body absorbs, and is both non-reversible and non-adjustable.

On average, more than half of patients lose 70% or more of their extra weight and then start to maintain. Long-term success is dependent on accepting new rules for eating and food selection, which is taught in the follow-up period after surgery.

What is Bariatric Revision Surgery?

Have you started to regain weight after initial success from gastric bypass? For some gastric bypass patients, over time, the small stomach pouch and the outlet that connects it to the small intestine can stretch out. As a result, patients begin to eat more food before they feel full. We offer a safe and effective endoscopic procedure to repair your enlarged pouch and outlet and return them to their original post-gastric bypass proportions.
