A minimally invasive, endoscopic weight-loss procedure that uses a suturing device to fold and stitch the stomach from inside, reducing its size and volume by about 70%.

Mechanism:

Smaller stomach → holds less food

Slower emptying into the intestines → prolonged fullness

Fewer calories absorbed → gradual weight loss

How ESG Differs from Surgery

ESG: No cutting/removing stomach tissue; sutures fold stomach like an accordion → reversible.

Laparoscopic Sleeve Gastrectomy: Removes a large portion of the stomach → permanent.

Who May Need ESG?

Adults with BMI ≥ 30 (obesity)

Failed lifestyle modifications (diet/exercise)

Want less invasive alternative to bariatric surgery

Motivated to follow a long-term lifestyle, diet, and exercise program
