The BMI Clinic team specialises in non-surgical and surgical weight loss. We combine innovative and minimally-invasive weight loss procedures (like the intragastric balloon) with intensive, evidence-based support programs delivered by a team of experts, to help patients lose their excess weight.

Our Sydney clinic, established in 2005, is the largest of its kind in Australia and our specialist doctors are world leaders in a range of endoscopic (non-surgical) weight loss techniques, including intragastric balloons, and newer techniques such as the endoscopic sleeve gastroplasty (ESG). We are regularly called upon to train other medical specialists in the use of these innovative techniques.

The BMI team recognises that there is no one-size-fits-all approach in weight loss and as such we regularly utilise a number of different techniques, including:

  • Intragastric Balloon (Orbera® & Spatz3®)
  • Endoscopic Sleeve Gastroplasty (ESG)
  • Laparoscopic Gastric Bypass
  • Laparoscopic Gastric Sleeve
  • Aspire Assist®

To maximise your weight loss, all of our programs include a personalised lifestyle retraining program, supervised by your doctor and a team of clinical experts including nurses, dietitians, exercise physiologists and behavioural coaches who work collaboratively with you to help achieve your weight loss goals.

12 Month Gastric Balloon Program starting from

Finance Available




The Intra Gastric Balloon is a non-surgical procedure available for weight loss. A soft, expandable, silicone balloon is placed inside the stomach via a camera that enters through the mouth. Once inserted into the stomach, the empty balloon is filled with sterile saline (salt water), occupying a large part of the stomach, creating a feeling of fullness.

Turquoise Coins


With programs starting from $6,950, a gastric balloon is an affordable weight loss option for most patients.



Over the past 12 years we have assisted thousands of people lose an average of 10-30kg with a gastric balloon.



Placement (and removal) of the intragastric balloon takes approximately 20 minutes in a day clinic and does not involve surgery - it is considered to be a minimally invasive procedure.



The intragastric balloon remains in the stomach for a period of up to 12 months and is then removed in the same way it was placed.

    How Emanuel Perdis’ fight with food changed his life

    I’VE spent most of my life detesting what I see when I look in the mirror. I struggled with my weight as a kid, so my father took me to a paediatrician.
    As soon as he found out I was being raised by my Greek grandmother, it was like, “Forget it; game over!” My grandmother adored us and she showed it by feeding us. She would serve me four eggs for breakfast. She’d cook lamb cutlets ...
