Gastric Sleeve Surgery Melbourne

Img Laparoscopicsleevegastrectomy

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 in Melbourne. Gastric sleeve surgery 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 Dr. Niruben Rajasagaram, our team offers a supportive, patient-focused approach to ensure optimal outcomes for each individual.

What is Gastric Sleeve Surgery?

sleeve gastrectomy

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 in 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.
