Endoscopic Sleeve Gastroplasty (ESG) is a minimally invasive, incisionless weight loss procedure designed to help individuals achieve significant and sustained weight reduction without surgery. It reduces the size of the stomach using advanced endoscopic suturing techniques, leading to early satiety, reduced food intake, and improved eating control.

During the procedure, a flexible endoscope is passed through the mouth into the stomach. Using a specialized suturing device, the stomach is internally stitched to create a sleeve-like shape, reducing its capacity by approximately 60–70%. As there are no external cuts or removal of stomach tissue, ESG preserves normal anatomy while effectively limiting food intake.

ESG is ideal for patients with obesity who have not achieved adequate weight loss through lifestyle changes alone and who may not be ready for or eligible for bariatric surgery. It is also beneficial for patients seeking a reversible or less invasive alternative to surgical weight loss procedures. In addition to weight reduction, ESG can improve obesity-related conditions such as type 2 diabetes, hypertension, fatty liver disease, and sleep apnea.

The benefits of Endoscopic Sleeve Gastroplasty include shorter hospital stay, minimal postoperative pain, faster recovery, and lower risk of complications compared to traditional bariatric surgery. Most patients can resume daily activities within a few days and experience steady, meaningful weight loss when combined with dietary counseling and lifestyle modification.

With proven safety and effectiveness, ESG has emerged as a valuable option in modern anti-obesity treatment. When performed by experienced therapeutic endoscopists as part of a multidisciplinary weight management program, it offers durable weight loss, improved metabolic health, and a better quality of life.
