The intragastric balloon is a non-surgical procedure which is performed under anaesthetic. A balloon-like device is inserted into the stomach using an endoscope (which is inserted through the mouth), and is then filled with saline. The procedure takes only half an hour.
The intragastric balloon can only be used for a maximum of 6 months and then must be removed in the same way it was placed.
For temporary use, only in super-morbidly obese people (BMI >50) to allow them to reduce their weight to a point where they become eligible for other weight loss procedures. In some cases, mildly overweight people utilise this procedure for temporary weight loss.
