This procedure is advised for individuals whose BMIs are in between 25 and 35, and who have failed to lose weight through diets and exercise. Gastric balloon is a balloon which is placed in the stomach through endoscopy. Due to the amount of space it takes within the stomach, the patient experiences the feeling of being full while eating less than before. As a result, patients start losing weight through eating less.
The procedure takes about 20 minutes to complete. The adjustable balloon remains in the stomach for 12 months.
