Procedure Information

Orbera Intragastric Balloon

The Orbera® Intragastric Balloon is a proven medical device for weight loss. It works by being inserted into the stomach, via gastroscopy under light sedation, and is filled with saline solution to a size that suits the patients individual needs.

Laparoscopic Adjustable Gastric Banding (LAP-BAND®)

The LAP-BAND® System is an adjustable gastric band which is a tool to aid long-term weight loss; it works by inducing a feeling of satiety (a feeling of fullness), therefore patients feel full on a much smaller amount of food.

Vertical Sleeve Gastrectomy (Gastric Sleeve)

The Sleeve Gastrectomy is the fastest-growing weight loss surgery in the world and regarded as the gold standard bariatric procedure for most patients with uncomplicated obesity. Also called "The Gastric Sleeve", it works by reducing the existing stomach to about 80% of the original stomach.

Frequently Asked Questions

What services does Winnett Specialist Group provide?
Winnett Specialist Group offers multidisciplinary weight-loss care, all in one place in Melbourne. Depending on your needs, this can include medical weight management, nutrition support with a dietitian, exercise and lifestyle coaching, and surgical assessment with a bariatric surgeon.
Do I need to see every specialist at Winnett Specialist Group?
Not everyone needs every clinician. Your plan is tailored to you, so you'll only see the specialists that match your goals and health needs. The benefit of our weight loss clinic in Melbourne is that the right experts are already in one place and work together to ensure your care remains consistent.
Does Winnett Specialist Group prescribe weight-loss medications?
Yes. Our Melbourne clinic can prescribe weight-loss medications for appropriately selected patients as part of a structured medical weight management plan. However, medication is not a 'quick fix'; it's usually combined with clinical monitoring plus nutrition and lifestyle support from the team, so it's safer, more effective, and easier to maintain results long term.
How do I know if weight-loss surgery or medications are right for me?
The right option depends on your health history, current weight and medical conditions, and what feels realistic and sustainable for you. If you book an appointment at our weight-loss clinic in Melbourne, we'll take the time to understand your goals, review your medical history, and talk through the pros and cons of each pathway.
Do you offer long-term care after weight-loss surgery and/or medications?
Yes. We provide ongoing follow-up and support to help you maintain results long term. Depending on your plan, aftercare can include regular reviews, nutrition guidance, lifestyle coaching, and continued medical support.
