Surgery may be appropriate for certain obese patients who have failed to achieve weight loss using other strategies and who have a full understanding of the procedure, risks and follow up requirements.
About 25% of Australian adults are obese (BMI >30 kg/m2). Obesity is a significant risk factor for the metabolic syndrome and other diseases. Weight loss (bariatric) surgery provides lasting reduction in weight and remission of obesity-related comorbidities. Current debate centres on the application of bariatric surgery in the nonmorbidly obese population and the choice of operation. A tailored approach to the choice of primary operation may lead to a reduction in the need for revisional surgery (Table).
