Gastric sleeve surgery, also known as a sleeve gastrectomy, is one of the most commonly performed weight loss procedures worldwide. By physically reducing the size of the stomach and influencing hunger-related hormones, this procedure helps people lose weight consistently while supporting long-term health and wellbeing.
What Is a Gastric Sleeve?
This procedure involves the surgical removal of around 75 percent of the stomach. The remaining part is shaped into a narrow tube or “sleeve” which can hold a much smaller volume of food. It is typically performed using keyhole surgery under general anaesthetic.
The sleeve also removes the part of the stomach responsible for producing ghrelin, the hormone that triggers hunger. With less hunger and smaller portions, patients find it easier to stay on track with healthy habits.
Who Is It For?
Gastric sleeve surgery is often recommended for individuals with a higher BMI who have struggled to lose weight through diet and exercise alone. It is particularly effective for those committed to long-term change, but who do not want their digestive system rerouted, as with other procedures.
However, it may not be suitable for those with conditions such as acid reflux, Barrett’s oesophagus, or swallowing difficulties. A full clinical assessment will help determine suitability.
