A gastric balloon ('intra-gastric balloon') is a weight loss device placed inside the stomach via the mouth and oesophagus in a non-surgical (endoscopic) procedure. It has the effect of reducing the capacity of the stomach and so decreases the level of hunger and restricts the size of meals that can be eaten. The procedure is reversible, that is, the balloon device can easily be removed.
