Part 1 of a 3-part series on the Endoscopic Adjustable Gastric Balloon by Dr Melvin Look, as featured in Shape Magazine September 2015.

The Gastric Balloon is a medical tool to help control your appetite by occupying space in the stomach. Self-motivation to keep to the recommended diet plan is essential and that is why results can be variable. l have used this device in hundreds of patients in the last ten years and have seen spectacular results as well as complete failures.

The Gastric Balloon is a silicone prosthetic device and needs to be removed after 6 months as it may be prone to leakage or rupture if left in the stomach beyond this period. They come in different designs from different makers and can be filled with air or saline. It is usually filled with a volume of between 400 to 700 mls. The main problem is that this volume cannot be adjusted once the insertion procedure is completed.

In my experience the fill volume can affect the efficacy of the device and my account for the unpredictable results in different people. A new product called the Spatz Adjustable Gastric Balloon introduced in Singapore earlier this year may address some of these problems. This device is safe for use up to 12 months. The longer treatment period may result in greater weight loss and less rebound weight gain after the balloon is removed. It also has an attached adjustment tube which allows us to calibrate the balloon to an effective size during the treatment period by a simple endoscopic procedure. Most patients may also require an adjustment after every 3 to 4 months to boost the weight loss effect.


I believe that the Gastric Balloon can be a useful adjunct to a successful weight loss program for those people in the BMI range of 25 to 35. It requires “re-programming” your body to less calories and an active lifestyle. These changes need time to take effect and sometimes repeat treatments may be necessary, but if done right can lead to sustainable results. Clinical studies using the Spatz Adjustable Gastric Balloon reported a 42.9-50.6% Excess Weight Loss at 12 months equivalent to a mean weight loss of 17.2 to 24 kg.
