  • Obesity is shaping up to be the major health care problem and one of the most frequent causes of preventable death in Western countries in the 21st century.

  • Bariatric surgery is the only current treatment that has been shown to achieve major and durable weight loss.

  • Major weight loss in the severely obese leads to total or partial control of a wide range of common and serious diseases, such as diabetes, heart disease and hypertension.

  • Laparoscopic adjustable gastric banding is the most common type of obesity surgery performed in Australia. It is effective, relatively safe and minimally invasive.

  • The blocks to broader application of bariatric surgery should be identified and resolved.
