The Safety and Efficacy of Bariatric Surgery in Australia

Bariatric surgery is a well-established and effective treatment for severe obesity in Australia, demonstrating strong safety and efficacy profiles supported by extensive national data. Australia’s national registry data underscores the safety of bariatric surgery. A comprehensive study encompassing 122,567 patients from 2012 to 2021 revealed a remarkably low perioperative mortality rate of 0.02%. Additionally, only 3.6% of procedures were associated with defined adverse events, such as unplanned readmissions or reoperations. The Australia and New Zealand Bariatric Surgery Registry (ANZBSR) further supports these findings, providing a population-based, observational quality improvement study that monitors the safety of bariatric surgery and enhances the quality of care received by individuals undergoing these procedures.


Furthermore, bariatric surgery is the most effective long-term treatment for obesity. It leads to significant and sustained weight loss and is associated with improvements in obesity-related comorbidities, including type 2 diabetes, hypertension, and sleep apnoea. As such bariatric surgery remains a cornerstone in the management of severe obesity in Australia, offering substantial and sustained health benefits. While it is associated with low complication rates, ongoing efforts are needed to address systemic barriers, including financial and geographic inequities, to ensure equitable access to this life-saving intervention.
