Endoscopic sleeve gastroplasty (ESG) using full-thickness suturing produces significant, durable weight loss (approx. 13-15% total body weight loss at 12 months) and improves metabolic markers, serving as a safer, reversible alternative to bariatric surgery.

If you are looking for a weight loss solution that is less invasive than surgery but more effective than dieting alone, ESG is a viable option. It involves an endoscopic procedure to suture the stomach, creating a sleeve that slows digestion and increases fullness. Expect about 13-15% weight loss over a year, combined with lifestyle changes. It is safer than traditional surgery and reversible.

GoodSupportsHIGH confidence
ESG has shown excellent short-term TBWL% in several meta-analyses that have reported 15.3–17.1% across 12–24 months follow-up... The recently published MERIT RCT involving 209 patients confirmed the safety and efficacy of ESG compared to lifestyle modification alone [9]. At 52 weeks, TBWL was 13.6% (SD 8.0) for ESG and 0.8% (SD 5.0) for control (p < 0.0001).

Why this rating

Supported by multiple RCTs (MERIT, MILEPOST, ESSENTIAL) and meta-analyses, though long-term data is still emerging.
