Sea Change Weight Loss Clinic

Newcastle Weight Loss and Obesity Surgery



We specialise in weight management and the surgical treatment of obesity

With GP, dietitian, psychologist and nursing staff, we are a multidisciplinary practice providing a holistic approach to weight loss and ongoing weight management. We believe this is the key to long-term success, and we are committed to providing the best possible outcome for every patient.

We provide weight loss surgery to patients with a high body mass index who have not achieved adequate weight loss with diet and exercise. Generally this includes patients with a BMI greater than 35. 

Our surgeons, Mark Gately and Martin McLeod were trained in the Hunter Region in General Surgery. Following this, they undertook subspeciality training in weight loss surgery in dedicated Bariatric centres. As such, they are trained to perform weight loss surgery and general surgical procedures including gallbladder and reflux surgery, hernia surgery and gastroscopy & colonoscopy.

Can I have surgery in a public hospital?

Our surgeons perform general surgery in public hospitals. Currently, in Newcastle, weight loss surgery is only offered in private hospitals. Patients without private health insurance can still pursue weight loss surgery and can discuss their options with the practice. Our practice also supports the use of superannuation to help fund weight loss surgery.

How much does weight loss surgery cost?

Costs will depend on your circumstances, e.g. insurance status, insurance fund and your ability to access superannuation. Please contact us for more information.

How long do I have to wait before surgery?

Our surgeons will aim to perform your surgery as early as possible. Most patients will have a minimum of a two week wait before surgery. Please let us know about your personal circumstances for example, work and personal commitments and we will always try to plan surgery at a time that suits you.
