Endoscopic Sleeve Gastroplasty

Endoscopic Sleeve Gastroplasty (ESG) is a non-surgical weight-loss procedure performed through the mouth using an endoscope — there are no external cuts or scars. The doctor places stitches inside the stomach to reduce its size by about 70%, helping you feel full after smaller meals. Recovery is faster than traditional weight-loss surgery.

Endoscopic Sleeve Gastroplasty is an incisionless, transoral endoscopic procedure that uses a full-thickness suturing device to placate the gastric body along the greater curvature, reducing functional gastric volume by approximately 70%. Unlike surgical sleeve gastrectomy, ESG preserves gastric anatomy and does not involve resection. Systematic reviews report mean total body weight loss of 15–20% at 12 months, with a favourable safety profile and hospital stay under 24 hours.

ESG bridges the gap between lifestyle interventions and traditional bariatric surgery. It offers a less invasive option with lower risk and faster recovery. Dr. Joseph Wang can help you understand whether ESG is a suitable option within your weight management journey.
