Upper Endoscopy (EGD) – Prep Instructions
Planning for the procedure
- You must have a driver who is 18 years or older present at check in and discharge. If you do not have a driver with you at check in, we will need to reschedule your appointment. This person must remain in the unit during your entire visit so that they are available as soon as you are ready to be discharged. You will not be discharged unless this person is in the unit. Because your judgment may be impaired after this procedure, you will not be released to take public transportation, a taxicab, or even walk home without another responsible adult present to accompany you.
- The entire procedure appointment may take at least 3–4 hours to complete. Please advise your driver that they will need to remain in the facility for the duration of the procedure.
- If you have diabetes, ask your health care provider for diet and medicine instructions.
- If you must cancel or reschedule your appointment, please call the Endoscopy Call Center as soon as possible at 734-936-9250 or toll-free 1-877-758-2626.
