Sleeve Gastrectomy (LSG)In this procedure, the surgeon creates a narrow tube and removes the remainder of your stomach. Hence, the capacity of the new stomach is much smaller than the original. It is usual to offer this operation as a first stage procedure to super obese patients – a second stage bypass procedure is then offered after the patient has lost some of the excess weight to make this type of surgery safer. In a small number of patients, a sleeve gastrectomy may be the only operation that is required. Unfortunately, there is evidence that 50% of patients may regain significant weight 5 year after surgery - this is because the “sleeve” stretches over time and can therefore hold more food. However, the operation can be repeated and extra stomach trimmed away or a gastric bypass / duodenal switch performed or a gastric band added to maintain long-term weight control.


  • Helps improve health problems as shown in table 1 and 2 above (Page 6 and 7)
  • You can expect to lose roughly 50-70 % of your excess weight, provided you follow the dietary advice
  • The amount of solid food that can be consumed at a meal is restricted
  • Food passes through the digestive tract in the usual order, allowing it to be absorbed fully by the body


  • Successful weight loss requires life-long adoption of healthy eating and self-control
  • The sleeve gastrectomy will eventually fail if you continue to force yourself to eat large meals
  • You may struggle to eat particular types of food, especially bread and meat
  • Weight loss is slower than that following Roux-en-Y gastric bypass surgery
  • The risk of a leak at the staple line is greater
