A gastric balloon typically stays in place for up to 6 months, after which it is removed using an endoscope. However, some types of gastric balloons can stay in place for up to 9 months. The exact duration can depend on the specific type of balloon used and the individual’s health condition.During this period, the balloon aids in weight loss by reducing the volume of the stomach, thus limiting food intake and promoting a feeling of fullness. It’s important to note that the gastric balloon is a temporary treatment, and maintaining the weight loss requires long-term lifestyle changes, including a healthy diet and regular exercise.
