Holistic approach to long-term weight loss

Sea Change Weight Loss Clinic takes a holistic approach to weight loss and ongoing weight management. We work closely with local GPs and other specialists, and our onsite team includes a dietitian, psychologist and clinical nurse specialist. We believe a holistic approach is key to long-term success and are committed to providing the best outcome for every patient. Typically, our patients have a BMI greater than 35, have not achieved adequate weight loss with diet and exercise, and are looking for a more permanent weight management solution.

Our weight loss surgeons, Dr Mark Gately and Dr Martin McLeod, were specialty trained in General Surgery in the Hunter region. They then undertook sub-speciality training in bariatric surgery in dedicated bariatric centres, both within Australia and internationally. They are highly trained to perform a variety of weight loss surgery procedures and hold regular education evenings at our clinic to share their knowledge and experience in achieving long-term weight loss success.

Next education evening @ our Merewether clinic is at 6pm on Wednesday 8 April 2020. All welcome. Reserve your place now

Is weight loss surgery safe?

Weight loss surgery, known as bariatric surgery, is generally regarded as safe surgery, in appropriately selected patients. Risks are lower than the longer-term risk of dying from heart disease, diabetes and other consequences of carrying more weight than a person’s organs can tolerate. Read our article on the outcomes and safety of weight loss surgery here.

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.
