Diabetes and Obesity

The Australian Diabetes Society (ADS) have a dedicated type 2 diabetes treatment website which also includes obesity treatment. The resources available may assist HCPs in deciding on suitable treatment options for Australian adults living with obesity and its comorbidities. Ethicon is proud to support the ADS clinical workshop: The Role of Bariatric Surgery in the Management of Obesity.

Resources and Support

Ethicon have created a patient website and downloadable resources providing plain-language information on the bariatric surgery journey, the different procedures, financial support, and real patient stories to help patients understand that bariatric surgery is a decision for life.

Public vs Private Pathways to Bariatric Surgery

It may surprise you to learn that <10% of all bariatric surgeries performed in Australia are performed in the public health system. Of over 700 public facilities, only 22 performed bariatric surgery in 2019.16 It is important that all HCPs advocate for more public funding, not just bariatric surgeons.
