Struggling with Weight Loss? Discover ESG at Sunway Medical Centre Malaysia

19/02/2026

Endoscopic Sleeve Gastroplasty (ESG) is a non-surgical, minimally invasive weight loss procedure performed endoscopically without any external incisions. This advanced bariatric endoscopy technique reduces stomach volume by up to 70% using internal sutures, helping patients feel full earlier and for a longer period of time.

By reducing stomach capacity, ESG helps patients naturally eat less and achieve sustainable, long-term weight loss. On average, patients may lose up to 17% of their total body weight within the first year after the procedure.

The ESG procedure is performed under general anaesthesia and has a strong safety profile when conducted by an experienced gastroenterologist.
