The installation of a gastric balloon typically takes about 20-30 minutes. The exact time can vary based on individual factors, but it is generally a quick procedure. This outpatient procedure is usually performed under sedation or mild anesthesia.
During the procedure, a specialist uses an endoscope (a long tube with a camera on the end) to insert the balloon through the mouth and into the stomach. Once the balloon is in place, it is filled with saline to partially fill the stomach, leaving less room for large amounts of food or drink.
