Compassionate, medically guided weight loss surgery in Melbourne.
Dr Ashok Gunawardene is a registered specialist general surgeon in Melbourne with advanced expertise in obesity surgery, upper gastrointestinal conditions, and advanced endoscopy. Leading the clinical team at Northern Surgical Care, his practice delivers modern, evidence-based treatments informed by current clinical guidelines, prioritizing clear practitioner-patient communication and collaborative care planning.
Through our primary sub-specialty weight loss clinic, OptiWeight Victoria, led directly by Dr Ashok Gunawardene, we provide a comprehensive, team-led approach to metabolic health. OptiWeight Victoria offers a complete continuum of services—ranging from clinical, specialist oversight of medical weight loss protocols through to state-of-the-art surgical interventions.
Our integrated, multi-disciplinary network provides you with seamless on-site access to specialized bariatric dietitians and psychologists, safeguarding your nutritional milestone looping and psychological support structures before, during, and long after your procedure.

Weight loss surgery (also known as metabolic, obesity, or bariatric surgery) is a highly effective clinical intervention designed to support systemic down-regulation of weight metrics in individuals suffering from severe obesity, particularly when traditional non-surgical modalities like dietary restriction and physical training regimens have failed to generate sustained physiological adjustments.
Bariatric procedures function primarily by altering your metabolic baseline. This is achieved by physically scaling down long-term stomach capacity (sleeve mechanics) or rerouting digestion pathways to safely curb calorie absorption and modulate hunger signaling hormones. To discover your baseline suitability parameters, every individual undergoes a comprehensive physical, metabolic, and psychological assessment loop directly with Dr Ashok Gunawardene.
Specialist weight loss interventions are clinically indicated for:
A non-surgical, reversible medical approach. A temporary, adjustable balloon structure is endoscopically inserted into the gastric space to naturally minimize intake portions and slow digestion limits. Typically managed over a 12-month timeline.
A premier bariatric procedure in Australia. A keyhole surgical technique removes approximately 80% to 90% of the stomach section, leaving a slender, sleeve-like tube. This structure curbs volumetric intake capacity and dynamically down-regulates hunger hormones.
The gold standard for advanced metabolic control. Creates a small, isolated upper gastric pouch and cross-links it directly into a lower quadrant of the small intestine. This structure targets sugar absorption loops and maximizes long-term hormonal resolution.
Also recognized as a Mini-Gastric Bypass. This simplified procedure balances the physical layout adjustments of a sleeve with a single loop connection bypass. This approach optimizes operation timelines while delivering advanced structural results.
Your initial orientation appointments involve a thorough medical overview staging layout, review of weight indicators, and diagnostic scoping (such as comprehensive blood screens or targeted gastroscopy validation). If a surgical path is chosen, you are provided with clear, structured protocols outlining your pre-surgical steps, liquid-phase transitions, and operational recovery windows.
Through the interconnected clinical pathways at OptiWeight Victoria, your surgical care loop is fully backed by nursing oversight, bariatric lifestyle coaching, and continuous nutritional tracking to ensure your safety margins are protected at every phase.
❓ What are the clinical risks of bariatric surgery?
All major abdominal operations hold baseline safety risks. However, modern keyhole weight loss surgery maintains an exceptional safety profile. Dr Ashok focuses heavily on customized patient triage selections, advanced surgical mechanics, and rigorous risk reduction to preserve patient safety.
❓ How much total weight can I expect to shed?
Weight loss loops scale based on the specific option selected, starting metrics, and lifelong adherence to lifestyle adjustments. Surgical interventions function as a tool to reset hunger loops, while ongoing dietary tracking secure long-term success.
❓ What is the typical surgical recovery window?
Most keyhole surgery patients return to light domestic activities within 1 to 2 weeks post-op. Complete, tailored recovery parameters and lifting restriction checklists are provided well before your admission dates.
❓ Which private hospital corridors do you operate across?
Dr Ashok treats private and self-funded individuals across Melbourne’s North and West, offering direct care pipelines at Northern Private Hospital (Epping) and St Vincent’s Private Hospital (Werribee).
