Gastric Sleeve

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. We work with clinics across the UK including in the heart of  London’s prestigious medical district.

The Procedure

The procedure is carried out via key-hole incisions in the abdomen. It involves laparoscopic surgery to remove 80% of the stomach, creating a smaller stomach. This aids weight loss by reducing stomach capacity and altering gut hormones like ghrelin and GLP-1, leading to appetite suppression. The rate of weight loss is not directly tied to the remaining stomach size, as changes in gut hormones play a significant role.

Frequently asked questions

As with all surgical operations, there are associated risks and a gastric sleeve is a more invasive procedure than a gastric band which is why it is important to choose a specialist bariatric surgeon with considerable gastric sleeve experience. In the hands of a highly experienced Healthier Weight surgeon, the gastric sleeve is still a safe and effective procedure. Read more about our sleeve centres and surgeons here.

Due to the considerable amount of weight that gastric sleeve patients typically lose, it’s possible that you will experience some excess, loose or saggy skin. This most commonly occurs in the abdominal apron, or trunk area. The amount of excess skin you’ll be left with following a gastric sleeve operation varies and will depend upon your age and weight before the procedure. Generally, the heavier and older you are, the more likely you are to have excess skin. Younger patients tend not to have as much lax skin due to greater natural skin elasticity. 

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.

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. Read more about the recovery time.

Your diet will change following the weeks out of surgery, however, after week 5 you can eat most foods, provided they don’t cause you discomfort. However, because you will be consuming less food in general, it is important that you include foods that are rich in protein, but low in fat and sugar. We encourage you to eat vegetables, fruit, whole grains, lean meat and fish. You will be provided with detailed nutritional information following your gastric sleeve operation.
