Endoscopic Sleeve Gastrectomy (ESG)
What is Endoscopic Sleeve Gastrectomy (ESG)?
Endoscopic Sleeve Gastrectomy (ESG) is a minimally invasive, incision-free weight loss procedure performed using an endoscope inserted through the mouth. The stomach is reshaped with internal sutures to reduce its capacity, helping patients feel full faster and consume less food.
What qualifies you for ESG?
ESG is suitable for patients with a BMI typically between 30–40 who have struggled with weight loss through diet and exercise alone. It is also ideal for individuals seeking a non-surgical alternative with quicker recovery and fewer risks than traditional bariatric surgeries.
Advantages of ESG
- Lower risk of complications compared to surgical procedures
- Reduced stomach volume without removing tissue
- Short recovery time
- No external incisions or scars
- Supports sustainable weight loss when combined with lifestyle changes
How ESG works
During the procedure, an endoscope equipped with a suturing device is passed into the stomach. The surgeon places a series of internal stitches to create a sleeve-like shape, reducing the stomach’s functional volume and slowing gastric emptying, enhancing early satiety.
