Read our Obesity research guide →The Bariatric Surgery Registry is collecting long-term health information from people who are having weight loss surgery in Australia and New Zealand. By tracking outcomes and experiences, researchers hope to understand which approaches work best and how to improve surgery results and patient safety over time.
Weight loss surgery is an important treatment for obesity, but doctors need better data to understand what works best for different patients and how to make these procedures safer and more effective.

Your surgeon or hospital will tell you about this registry and send you information in the mail. You'll have two weeks to decide if you want to participate — you can join fully, share data but opt out of follow-up contact, or skip it entirely. Participation is completely voluntary, and your choice won't affect your care or relationship with your surgical team.
