Summary: Insights from the Australian Bariatric Surgery Registrar Data (2012-2021)

At Laneways, we recognise the importance of informed decision-making in managing the chronic health condition of obesity. Our latest blog explores recent findings from the Bariatric Surgery Registry (BSR), which provides valuable data on the safety and effectiveness of metabolic-bariatric surgery in Australia. The BSR highlights key outcomes, including low complication rates, significant weight loss, and improvements in diabetes management among patients. We also acknowledge that individuals can live in larger bodies and be healthy and well without having obesity. The term “obesity” is used strictly as a medical condition and never as a judgment on a person’s physical shape or worth. Read more to discover the insights from the BSR data and their implications for patient care at Laneways.

Metabolic-bariatric surgery is a well-established treatment for obesity, and we’re fortunate to have an updated evidence report highlighting its safety and efficacy in Australia.

The Bariatric Surgery Registry (BSR), run by Monash University, is a national registry that tracks outcomes for patients undergoing bariatric surgery in Australia. It collects data on weight loss, diabetes status, and surgical outcomes to improve safety, clinical guidelines, and patient care. Supported by leading surgical organisations and funded by the government, the BSR ensures high-quality, standardised data to drive research and quality improvements in bariatric surgery.

The BSR has recently published data from 2012–2021, covering approximately 122,000 patients. Key findings include:

✔️ Safety: 90-day complication rate was 3.6%, with low rates of serious adverse events.


✔️ 
Weight Loss: At 5 years, average total body weight loss (TBWL) was 34.9% for one-anastomosis gastric bypass, 30.7% for Roux-en-Y gastric bypass, 26.5% for sleeve gastrectomy, and 17.6% for gastric banding.

✔️ Diabetes Improvement: Of those on diabetes medication before surgery, 71.6% no longer needed it at 1 year, and 61% at 5 years.

These results demonstrate that bariatric surgery is safe, effective for weight loss, and significantly improves diabetes management in real-world settings.
