The balloon partially fills the stomach up and limits the intake of food. Patients report satiety for longer time with less calories. The procedure does not require surgery and takes place at the clinic under sedation.

The gastric balloon is comprised of a soft, well-tolerated silicone, which is filled with air or saline. The filled gastric balloon creates a feeling of fullness. Generally, the balloon is removed after 6-12 months dependent on the balloon type.
