What Is Bariatric Surgery?
Bariatric surgery is a group of surgical procedures designed to achieve significant weight loss by modifying the digestive system. The primary goal is to reduce the risk of obesity-related conditions — and in many cases, to treat conditions that are already established, such as Type 2 Diabetes, hypertension, and obstructive sleep apnoea.
Bariatric surgery is not a cosmetic procedure or a shortcut — it is a serious, evidence-based medical intervention that has been shown to produce more significant and more durable weight loss than any non-surgical treatment. It is also one of the most effective interventions available for metabolic disease.
The decision to proceed with bariatric surgery is a significant one that requires careful assessment, preparation, and long-term commitment. At MedSurg Weight Loss, our team works closely with each patient to ensure the decision is well-informed and that the right procedure is matched to the right person.
Types of Bariatric Surgery Available in Australia
Four main bariatric procedures are currently performed in Australia. Each works through a different mechanism, and each has its own advantages, risks, and suitability criteria. Your bariatric surgeon will recommend the most appropriate option based on your individual health profile and goals.
Removes ~80% of the stomach, creating a tube-shaped sleeve. The most commonly performed bariatric procedure in Australia. Restricts food intake and alters hunger hormones.
Creates a small stomach pouch and reroutes the small intestine, producing restriction, malabsorption, and powerful hormonal changes. The gold-standard bariatric procedure.
A single-anastomosis bypass procedure — technically simpler than RYGB with similarly strong outcomes. Bypasses a greater length of small intestine than RYGB.
Places an adjustable silicone band around the upper stomach to restrict food intake. Less commonly performed now than sleeve or bypass procedures.
The Bariatric Surgery Journey at MedSurg
MedSurg Weight Loss collaborates closely with our surgical partners at Total Upper GI Surgery to support patients at every stage of the surgical weight loss journey — not just on the day of surgery.
Our doctors conduct thorough metabolic health assessments — including blood tests, cardiovascular screening, and psychological readiness — to determine suitability and identify the best procedure for your individual circumstances.
Most patients undertake a pre-surgical VLCD (very low calorie diet) to shrink the liver and reduce operative risk. Our dietitians and doctors support you through this stage.
All procedures are performed laparoscopically (keyhole surgery) by our specialist surgical partners — with typical hospital stays of 1–3 nights and return to normal activities at around the 2-week mark.
Ongoing follow-up is essential — including regular blood tests for nutrient deficiencies, dietitian reviews, medical monitoring, and psychological support. MedSurg provides this care for all surgical patients, including those who had surgery elsewhere.
