The sleeve in weight-loss surgery refers to the stomach after a portion has been removed during a sleeve gastrectomy. The remaining part of the stomach is shaped like a narrow tube or sleeve, significantly reducing the amount of food the stomach can hold and aiding in long-term weight loss.

Endoscopic Sleeve Gastroplasty (ESG) is a non-surgical weight-loss procedure where a gastroenterologist uses an endoscope to stitch the stomach into a smaller size, reducing its capacity. Unlike traditional bariatric surgery, ESG is performed through the mouth and doesn’t involve cutting or removing any part of the stomach. Recovery is quicker, and the procedure is reversible, but the weight loss achieved is typically less significant than with RNY or gastric sleeve surgery.

A pre-surgery diet prepares the body for bariatric surgery, typically focusing on reducing liver size and overall fat to make the procedure safer. This high-protein, low-carbohydrate diet often lasts for 1-2 weeks before surgery. Patients must follow a strict plan of liquids and protein shakes to shrink the liver and facilitate surgery.

Sleeve surgery in the UK refers to sleeve gastrectomy, one of the most popular weight-loss surgeries. It is often recommended for individuals with severe obesity who have not had success with diet and exercise. The NHS provides this surgery for eligible patients, but private clinics also offer the procedure, often with shorter waiting times.
