Sleeve gastrectomy

Sleeve gastrectomy or gastric sleeve, is a keyhole procedure to remove approximately 80% of the stomach, including the area where the hunger hormone, ghrelin, is produced. The resulting smaller gastric volume and loss of appetite thus leads to rapid weight loss.

Sleeve gastrectomy is suitable for people aged between 18 and 65 who have failed to lose weight by means of diet or exercise and who have a BMI of 40 or higher. It may also be considered in patients with a BMI of 35-40 who have co-morbidities such as diabetes, hypertension or sleep apnoea.

With the lowest complication risk and highest lifelong comfort compared to other methods, sleeve gastrectomy has become the favoured procedure with bariatric surgeons worldwide.

Gastric bypass

Gastric bypass offers a permanent solution to the diseases associated with obesity, particularly type 2 diabetes. It is suitable for patients who have a history of multiple unsuccessful attempts at losing weight with diet, those with excess weight that may jeopardise health, people with a BMI of 40 or higher, or people with a BMI of 35-40 with any obesity-associated co-morbidity.

Performed laparoscopically (keyhole surgery), the procedure shrinks the stomach to a small pouch and causes the food to bypass the upper portion of the small intestine. This has a dual effect: both the amount of food that can be ingested and the amount of nutrients that can be absorbed is reduced.

Most patients who undergo gastric bypass surgery successfully lose weight and maintain their excess weight loss in the long term. The role of a dietician is important in the postoperative period to ensure that patients adapt to the dietary changes required, however the rates of postoperative patient satisfaction are high in terms of the psychological and physical effects.

Non-surgical weight loss (gastric balloon)

An intragastric balloon is a soft, expandable balloon that is inserted endoscopically into the stomach. Once placed, the balloon is filled with liquid, generating a feeling of ‘fullness’ when smaller food portions are ingested. A gastric balloon may be in place for 6 or 12 months.

The gastric balloon is designed to work in conjunction with dietary and lifestyle changes. It is suitable for overweight people with a BMI over 25 who have failed to lose weight with diet or exercise, who have lost motivation or who do not want to undergo a surgical procedure.
