Preparing for Upper GI Endoscopy

To ensure there is no food obstructing the view and to see the upper GI tract clearly, providers typically ask patients not to eat or drink for up to eight hours before an upper GI endoscopy. Some regular medications may also need to be adjusted or stopped for a short time before the procedure. Patients should talk to their providers about all prescription and over-the-counter medications, vitamins, and supplements they are taking prior to any procedure.
