Weight Loss Surgery FAQ's

We have a variety of clinics around greater London, including Central London, Watford and Hertfordshire 

The gastric sleeve (laparoscopic sleeve gastrectomy) is the world’s fastest-growing weight loss procedure, surpassing gastric band and bypass surgeries in NHS popularity. This simple concept involves laparoscopic access, cutting and removing about 80% of the stomach.

Post-surgery, food follows the same path, but with a significantly smaller stomach. The sleeve facilitates weight loss by reducing stomach capacity and altering gut hormones (ghrelin and GLP-1), suppressing appetite.

Notably, excess body weight loss is rapid, and it’s crucial to understand that weight loss isn’t directly tied to the remaining stomach size; gut hormone changes drive effective weight loss in both ‘tight’ and ‘loose’ sleeves.

Most sleeve patients will stay in a hospital for 1 night before going home. You should start to feel much more comfortable around 2 weeks after surgery, but it typically takes around 6 to 8 weeks for your stomach to heal completely.

On average we expect weight loss results for gastric sleeve patients to be approx 60-70% of their excess weight during the first two years, although most of the weight is lost during the first year. Some people will inevitably do better than this, and some not so well.
