Bariatric intragastric balloon therapy is a relatively new form of bariatric surgery, which involves a balloon being endoscopically placed and inflated inside the lumen of the stomach. The balloon resides in the stomach and the mechanism of action is presumably due to stretching the stomach, inducing postprandial fullness and early satiety, although it has also been proposed that the mechanism of action may be delayed gastric emptying 3.
There are a number of different types of balloons, all of which assist in weight loss 1, albeit possibly not more so than conventional management 2. Fluid-filled gastric balloons have been available for longer than their air-filled counterparts. It has been claimed that air-filled gastric balloons cause fewer side effects such as nausea and vomiting due to their comparative lightness4. Adverse outcomes include difficulty with removal, gastric ulcers and spontaneous deflation.
