Scarless gastric sleeve surgery, also known as endoscopic sleeve gastroplasty (ESG), is a revolutionary weight loss procedure that offers the benefits of traditional gastric sleeve surgery without visible scars. This minimally invasive technique is performed using an endoscope, a flexible tube with a camera and suturing device, which is inserted through the mouth to reshape the stomach. By reducing the stomach's size, patients experience significant weight loss and improvements in obesity-related health conditions.
