A gastric balloon, also known as a gastric balloon, is a temporary medical device that is placed in the stomach and inflated. This method is a method used in the treatment of obesity and requires a surgical intervention. It can be preferred as an alternative to surgical intervention in cases of obesity where diet and exercises do not give sufficient results and the person's weight loss efforts are ineffective.

The balloon placed in the stomach reduces the amount of food in the stomach by limiting food intake. In this way, the person experiences a feeling of satiety earlier, the speed of food passage in the stomach decreases, and weight loss becomes easier.
