Gastric Sleeve Surgery

Have you struggled with weight loss for years, despite diet and exercise? Gastric sleeve surgery, offered by Southern Weight Loss and Laparoscopy Limited, could be the life-changing solution you’ve been searching for. This minimally invasive procedure can help you achieve significant and sustainable weight loss, improving your health and overall well-being.

What is Gastric Sleeve Surgery?

The gastric sleeve, or sleeve gastrectomy, is a restrictive procedure that reduces the stomach’s volume and involves no reconfiguration of the intestines.

Sleeve gastrectomy is the most common bariatric surgery procedure performed worldwide. Gastric sleeve surgery also makes patients less hungry because the portion of the removed stomach contains the cells that release the appetite-controlling hormone Ghrelin.

Weight Loss After Gastric Sleeve Surgery:

Gastric sleeve surgery can be highly effective for weight loss. 12- 18 months after a Sleeve gastrectomy, weight loss ranges from 60-70% of your excess weight before surgery. So, on average, a typical patient who is 50 kilogrammes overweight will lose 30 kilogrammes.

Currently, the published data suggests that the risk of complications with a gastric sleeve is similar to that of a gastric bypass. The evidence suggests that the long-term weight loss is less than that of the Gastric bypass. After the surgery, your stomach heals for a while so it’s advisable to change your eating habits. You’ll need to eat small meals for your small stomach.

Using keyhole surgery and advanced stapling devices, most of the fundus and body of the stomach are permanently removed and the capacity of your stomach is reduced by approximately 85%. This turns your stomach into a narrow tube, approximately 1cm in diameter, which has a volume of less than 100mls.

Patients stay in the hospital for two nights and will usually return to work within two weeks, however, each patient is different.
