Weight Loss Surgery



The Sleeve Gastrectomy is also referred to as gastric sleeve, tube gastrectomy or vertical sleeve and is a minimally invasive procedure that combines a restrictive and metabolic type of weight loss surgery. The size of the stomach is reduced by up to 80% using a surgical technique to decrease its storage capacity. By removing up to 80% of the stomach, this will produce chemical changes in the body that decreases your appetite. The procedure includes removing the portion of the stomach that produces specific hormones such as leptin and ghrelin which control energy and appetite balance. This will dramatically decrease appetite, whilst increasing energy levels, reducing the conversion of calories to fat and more effectively regulate your blood sugar levels.

To perform the gastric sleeve the bariatric surgeon will remove the fundus part of the stomach which is located on the left, above the lower end of the oesophagus, along with most of the stomach, whilst leaving 20% of the remaining stomach shaped like a banana which is connected to the oesophagus and the upper part of the small intestine.


The Gastric Sleeve is the most common bariatric procedure carried out due to its success for getting the desired results for weightloss, as well as its resolution of obesity related conditions. Gastric sleeve patients can expect to lose between 60-70% of their excess body weight within 12-18 months.


Gastric Bypass surgery is a procedure where the stomach is divided into a small upper pouch approximately the size of a golf ball, separated from the rest of the stomach using a stapling device. This pouch is then attached to the upper small intestine called the jejunum, divided and rearranged to be brought up to the small pouch. All food and fluids from then on “bypass” the upper section of the intestine and lower section of the stomach, decreasing the number of calories that the body would usually absorb.


The Gastric Bypass surgery has a low complication rate and also has a high level of success in reducing excess weight. The surgery also has a greater effect on health problems related to obesity.
