Providing weight loss surgery in Perth, Western Australia

Perth Obesity Surgery is a trusted Perth-based weight loss clinic that specialises in bariatric surgery.

Our practice offers a complete weight management solution including access to two of Perth’s most accomplished bariatric surgeons, who can provide expert assessment for a range of conditions and create an individualised treatment plan.

Focused on health promotion, disease minimisation and a rational approach to intervention, our team at Perth Obesity Surgery is committed to supporting patients through their weight loss journey.

We take the time to understand your situation and work at your pace to help you achieve your weight loss goals, now and in the future.

We are ideally located to serve the needs of the southern Perth communities of Mandurah and Rockingham, aiming to facilitate quality and compassionate consultation and treatment close to our patient’s home.

Perth Obesity Surgery and Southern Surgical Care

Alongside weight loss surgery in Perth, we also provide a general surgical service through our sister practice, Southern Surgical Care.

While Perth Obesity Surgery is focused on bariatric surgery to help with obesity and its related diseases, Southern Surgical Care manages most other surgical concerns.

The two services utilise the same consulting rooms and specialist staff and are committed to providing the same dedication to patients’ needs. Therefore, our surgeons can discuss any concerns related to surgery, not only those related to bariatric procedures.
