Endoscopic Sleeve Gastroplasty (ESG): A Patient Information Guide

Endoscopic Sleeve Gastroplasty (ESG) is a minimally invasive, incision‑free weight‑loss procedure designed for adults with obesity who have not achieved sufficient results through diet, exercise, or medical therapy. It reduces stomach volume using internal sutures placed through an endoscope, helping patients feel full sooner and eat less. ESG has gained global acceptance as a safe, effective option for selected patients seeking a non‑surgical alternative to bariatric surgery.

Bariatric surgery is a major medical decision.

It can support significant weight loss and improve obesity-related health conditions, but it also requires long-term commitment.

That is why your first consultation should not feel rushed.

It should help you understand your options, your risks, your expected results, and your responsibilities after surgery.

The goal is not to ask as many questions as possible.

The goal is to ask the right questions.

Gastric bypass (Roux-en-Y)

Gastric bypass, also called Roux-en-Y (roo-en-wy) gastric bypass, is a type of weight-loss surgery that involves creating a small, egg-sized pouch from the stomach. The newly created pouch is then connected directly to the small intestine. After gastric bypass, swallowed food goes into this small stomach pouch and then directly into the small intestine, thereby bypassing most of the stomach and the first section of the small intestine.
