Sleeve Gastrectomy (LSG)

This procedure removes a large portion of the stomach and creates a narrow, banana-shaped tube that is connected to the small intestine

This procedure involves the removal of approximately 80% of the stomach. The surgery achieves weight loss through both restriction, by creating a smaller stomach, and complex metabolic changes in the gastrointestinal hormones. As a result, patients experience reduced hunger and earlier feelings of fullness when consuming food.

On average, individuals undergoing sleeve gastrectomy can expect to lose around 65 to 70% of their excess weight within a period of twelve to eighteen months.

Sleeve gastrectomies are typically performed using laparoscopic techniques and require a hospital stay of two to three days. Most patients can resume work within two to four weeks following the procedure.


  • Significant weight loss: Sleeve gastrectomy can lead to significant weight loss for patients who are obese.

  • No foreign objects implanted in the body: Unlike some other bariatric surgery procedures, sleeve gastrectomy does not require any foreign objects to be implanted in the body.

  • No need to change the digestive process: Sleeve gastrectomy does not involve changing the digestive process, so patients can still enjoy most of the foods they love.

  • No need for ongoing adjustments: Unlike some other bariatric surgery procedures, sleeve gastrectomy does not require ongoing adjustments to the stomach or other parts of the digestive system.

  • Short hospital stay: Sleeve gastrectomy typically requires only a short hospital stay, so patients can return to their normal lives more quickly.


  • Potential for bleeding or infection: Like any surgical procedure, sleeve gastrectomy carries a risk of bleeding or infection.

  • Some patients may experience acid reflux or dumping syndrome: After sleeve gastrectomy, some patients may experience acid reflux or dumping syndrome, which can cause discomfort or other symptoms.

  • Long-term changes to diet and lifestyle may be required: After sleeve gastrectomy, patients may need to make long-term changes to their diet and lifestyle to maintain their weight loss.

  • Some patients may need additional surgeries if they regain weight.

  • Sleeve gastrectomy is not reversible: Once a patient has undergone sleeve gastrectomy, the changes to their stomach are permanent.

Conclusion: Though sleeve gastrectomy is generally considered a safe procedure, serious/major complications can still occur, although they are rare. Some possible complications include bleeding, infection, staple line leaks, and pulmonary embolism. It's important to discuss potential risks and benefits with your surgeon before undergoing any bariatric surgery procedure.
