What is weight loss surgery?

Surgery is a safe and effective way to tackle obesity and obesity-related health conditions. Gastric surgery has been adapted over 50 years to improve patient safety. While different surgical procedures vary in their methods, the end result is always the restriction of the stomach’s capacity (sometimes including other organs of the digestive system) to retain excess food and absorb nutrients. With a smaller stomach pouch the patient feels fuller after eating much smaller portions of food. 

Weight loss surgery is recognised in medical science for making life-changing improvements to the health of people living with obesity. In particular, Type 2 Diabetes and high blood pressure are potentially life-threatening diseases that can be improved and even reversed with surgey.  

Eligibility for weight loss surgery is subject to a medical criteria. A procedure might be offered to people with a Body Mass Index (BMI) of 40 or more. If your BMI is between 35 and 40 then you can also be recommended for surgery if you have a life-threatening health condition related to obesity.
