What is Gastric Sleeve Surgery?

Gastric sleeve surgery (sleeve gastrectomy) is a minimally invasive procedure that removes approximately 80% of your stomach, creating a smaller, banana-shaped stomach. This advanced laparoscopic technique not only restricts food intake but also reduces hunger hormones, helping you feel satisfied with smaller portions and supporting long-term weight management.

Who is Gastric Sleeve Surgery For?

This procedure is typically recommended for individuals who:

  • Have a Body Mass Index (BMI) of 40 or higher, or
  • Have a BMI of 35 or higher along with obesity-related health conditions such as type 2 diabetes, high blood pressure, or sleep apnoea

 

Gastric sleeve surgery is ideal for people who have struggled with weight loss despite trying diet, exercise, and medical treatments. It offers a long-term solution when other methods have not delivered lasting results.

Benefits of Gastric Sleeve Surgery

  • Significant, long-term weight loss – Gastric sleeve surgery helps you achieve and maintain substantial weight loss by permanently reducing stomach size. It limits food intake and promotes healthier eating habits.
  • Reduced hunger hormones – The procedure lowers levels of the hunger hormone ghrelin, helping you feel full sooner and reducing cravings for overeating.
  • No rerouting of intestines – Unlike gastric bypass, this surgery maintains your natural digestive system, reducing the risk of complications while still effectively promoting weight loss.
  • Improved portion control – A smaller stomach capacity helps you eat less and feel full faster, making portion control easier and supporting long-term weight management.
  • Better management of obesity-related conditions – Weight loss following gastric sleeve surgery can lead to improvements in conditions like diabetes, high blood pressure, and sleep apnoea, reducing the need for medications.
