Gastric Sleeve Surgery Melbourne

Gastric Sleeve Surgery Melbourne

Gastric sleeve surgery or vertical sleeve gastrectomy is one of the most commonly performed procedures in Australia and globally, and it is considered both safe and effective for people who need medical support in their weight management journey. According to health.gov.au, two in three Australian adults are living with overweight or obesity, which can lead to a range of health conditions and the need for obesity surgery. Gastric sleeve surgery in Melbourne can be an important option when other methods, such as lifestyle changes and medications, have not provided lasting results.

It is most commonly recommended for individuals who have not achieved sufficient results through lifestyle modifications and need a long-term, medically supervised solution. For suitable candidates, gastric sleeve surgery offers a clinically supported way to improve health outcomes, and it not only helps in reducing hunger and food intake but can also lead to improvements in health conditions such as type 2 diabetes, high blood pressure, sleep apnoea and joint pain.

We are committed to offering compassionate, minimally invasive care through laparoscopic sleeve surgery for those considering this transformative option. Under the expert care of Mr. Niruben Rajasagaram, our team offers a supportive, patient-focused approach to ensure optimal outcomes for each individual.

What is Gastric Sleeve Surgery?

Vertical Sleeve Gastrectomy Melbourne

Gastric sleeve surgery, or sleeve gastrectomy, is a minimally invasive weight loss surgery. During the surgery, around 75–80% of the stomach is carefully removed. The remaining stomach is reshaped into a narrow, tube-like “sleeve” which holds less food and produces fewer hunger hormones. 

The surgery may positively influence other hormones such as:

  • Reduces the Hunger hormone “ghrelin”

This procedure has two key effects: it reduces appetite naturally, helping you feel full with smaller portions, and it lowers overall calorie intake in a gentle, sustainable way. Together, these changes support long-term weight management without the need for restrictive dieting.

At our weight loss centre gastric sleeve surgery Melbourne is performed using keyhole (laparoscopic) techniques, which allow for quicker recovery, less discomfort, and smaller incisions.

It is commonly recommended for patients with a Body Mass Index (BMI) over 35, or those with a BMI over 30 who also have health concerns.

Our patients’ experiences reflect the care, support, and outcomes they receive throughout their treatment journey. These testimonials share real stories about recovery, confidence, and improved quality of life, helping others understand what to expect from the process.

Mr Niruben and his team have been great. I had a gastric sleeve done. After the surgery, I had gas pain (which is normal after surgery) but I never had any pain around the surgery site. I never needed any heavy duty pain medication and was only on Panadole for 2 days. I have already passed on Mr Niruben contact details to 2 of my friends who are wanting to get the surgery done.

Frequently Asked Questions About Gastric Sleeve Surgery in Melbourne

    • HOW MUCH OF THE STOMACH IS REMOVED IN GASTRIC SLEEVE SURGERY?

      Approximately 75–80% of the stomach is removed during gastric sleeve surgery, leaving a narrow, sleeve-shaped stomach that holds significantly less food than before. This helps reduce meal portions and may decrease hunger by lowering ghrelin production. Because part of the stomach is permanently removed, gastric sleeve surgery is irreversible.

    • Eligibility is generally based on a BMI of 40 or above, or a BMI between 35 and 39.9 with obesity-related conditions such as type 2 diabetes, sleep apnoea, or high blood pressure. In selected cases, patients with a BMI of 30 or above and significant metabolic disease may also be considered. Your eligibility also depends on your overall health, previous weight loss efforts, and readiness for long-term lifestyle changes. You can learn more about the assessment criteria on our Eligibility for Gastric Sleeve Surgery page.

    • The cost depends on your private health insurance cover and individual circumstances. Patients with appropriate bariatric cover generally have lower out-of-pocket expenses after Medicare and health fund rebates, while self-funded patients pay the full cost of treatment. A personalised quote outlines all expected fees. If you're planning for surgery, understanding what influences the overall cost of gastric sleeve surgery can help you prepare.

    • The procedure usually takes between 1.5 and 2 hours and is performed laparoscopically under general anaesthetic using several small incisions. This minimally invasive approach generally results in less pain, smaller scars, and faster recovery than open surgery.

    • Most patients stay in hospital for one to two nights. Gentle walking usually begins on the day of surgery or the following day. Many people return to desk-based work within two to three weeks, while recovery continues over four to six weeks.

    • Preparation usually includes a two-week pre-operative diet, blood tests, a gastroscopy (usually performed on the day of surgery to reduce costs), and an anaesthetic assessment. Some medications, including blood thinners, diabetes medicines, and GLP-1 weight loss injections, may need to be adjusted or temporarily stopped before surgery. Following the recommended preparation plan helps support a smoother surgical journey, and understanding how to prepare for gastric sleeve surgery can help you feel more confident before your operation.

    • Many patients lose around 60–70% of their excess body weight within two years, with the fastest weight loss occurring during the first three to six months. Long-term success depends on healthy eating, regular exercise, and ongoing follow-up. Individual results vary.

    • Your diet progresses from clear liquids to full liquids, pureed foods, soft foods, and then a modified normal diet over approximately six to eight weeks. Protein should be prioritised at every meal, and your bariatric dietitian will provide personalised guidance.

    • Light walking is encouraged from the first day after surgery. More structured activities, such as cycling, swimming, and gym-based exercise, can usually begin after four to six weeks, once approved by your surgeon. Heavy lifting should be avoided during early recovery.

    • Yes. Lifelong vitamin supplementation is generally recommended to help prevent nutritional deficiencies. Regular blood tests help ensure your supplements remain appropriate over time.

    • No. Gastric sleeve surgery is permanent because the removed portion of the stomach cannot be replaced. If additional treatment is needed, the sleeve can sometimes be converted to gastric bypass.

    • Yes. Gastric sleeve surgery can significantly improve type 2 diabetes for many patients, with some experiencing remission, particularly when surgery is performed earlier in the course of the condition. The most appropriate procedure depends on your individual health.
