A sleeve gastrectomy is a procedure that limits the amount of food you can eat by reducing the size of your stomach. Like other metabolic surgeries, it also helps to establish a lower, healthier body fat set point by changing the signals between the stomach, brain, and liver. Many experts now consider the sleeve gastrectomy as the new gold standard for weight loss surgery. It can help you lose weight without the nutritional risks of gastric bypass surgery.

How does Gastric Sleeve Work?


The surgeon creates a small stomach “sleeve” using a stapling device. This sleeve will typically hold 50 ml to 150 ml and is about the size of a banana. The rest of the stomach is removed.

This procedure works in part by restricting the amount of food (and therefore calories) that can be eaten without bypassing the intestines and absorbed. By removing part of the stomach, there is a rapid reduction in the hormone “Ghrelin” which is thought to stimulate appetite. You will feel satisfied quickly.


  • Limits the amount of food that can be eaten at a meal.
  • Allows the body to adjust to its new, healthier set point.
  • Food passes through the digestive tract in the usual order, allowing vitamins and nutrients to be fully absorbed into the body. 
This is the main advantage of sleeve over bypass. There is no malabsorption as vitamins, minerals and proteins are well absorbed.
  • No post-operative adjustments are required.
  • In clinical studies patients lost an average of 66% of their excess weight.
  • Shown to help resolve high blood pressure (49%), obstructive sleep apnea (60%), and to help improve type 2 diabetes (45%) and high cholesterol* (77%). In many countries, sleeve Gastrectomy has become the gold standard for the surgical treatment of morbid obesity.
