Preparing for a procedure with UVA Digestive Health, Endoscopy

We are so glad that you chose us to provide your care. Please note that UVA performs endoscopic procedures at two locations.  You can confirm the location of your procedure by referring to your appointment reminder letter. Please follow the endoscopy guidelines and preparation instructions to help make for a successful experience. 

□     IMPORTANT: If you have diabetes or are on a blood thinner other than aspirin, please call the doctor that ordered your procedure at least 10 days before your procedure date for further instructions regarding medication adjustments. 

□     You MUST have a driver on the day of your procedure: As you will receive anesthesia medications on the day of your procedure, you must have a responsible adult 18 years or older who can drive you home.  For your safety, UVA Health recommends that this person stay with you for several hours after your procedure.  You may not drive for 24 hours after your procedure. To help control the number of people in our waiting room, we will only allow 1 visitor per patient in the building. We apologize for the inconvenience, but children will not be allowed in the waiting room.

□     Medication and allergy information: Please bring a complete list of your current medications, their doses, and any allergies you may have.

□     Pacemaker or Internal Defibrillator: Please bring your device information card with you. 

□     CPAP Machine:  If you have sleep apnea and use a CPAP machine at home, please bring it with you even if you rarely use it.  Ensure that all components, including the power cord, are included.

□     Personal belongings: Please leave all jewelry and other valuables at home.  Please do not wear contacts the day of your procedure.  If you wear glasses, hearing aids, or dentures, please bring a case with you to store these items during your procedure.

We strive to provide the safest care for all of our patients.  As a result, some procedures may take longer for some patients than others.  Please arrive 45 minutes prior to your appointment time.  We ask for your patience and that you plan to be with us at least 3 to 4 hours.    

If you must cancel or reschedule your appointment, please call the UVA Endoscopy scheduling team as soon as possible at: (434) 924-9999.


Suprep Bowel Preparation Instructions

Two weeks before your colonoscopy:

□  Call your pharmacy two weeks prior to your procedure. Tell them you are ready for them to fill your prescription for the colonoscopy bowel prep kit.

□   If you are on medications (other than aspirin) that thin your blood or if you take medications for diabetes, you will need to let your family doctor know you are planning to have a colonoscopy and ask for instructions regarding this medication.

□   Please note that UVA performs colonoscopies at two locations. Please confirm your location by referring to your appointment reminder letter.


Five days before your colonoscopy:

□   Start a low fiber diet. Low Residue/ Low Fiber food list attached.

□   Stop iron, including vitamins that contain iron.

□  Arrange a ride home with a friend or family member.

□   Have plenty of clear liquids available at home, clear liquid diet attached.

□   If you wish, buy soft toilet paper, moist wipes or external ointment.


One day before your colonoscopy:

□  Have only clear liquids, 1-2 glasses per hour. Follow the lists below.

□   Do not eat solid foods or milk products, all day.

At 5:00pm

□   You will have two bottles of prep, save one for the day of your colonoscopy.

Frequently Asked Questions:

Why Is It Important To Get Cleaned Inside? Your doctor must be able to see in order to complete the colonoscopy exam. If your colon is “dirty” on the inside, your doctor may not be able to see important things like polyps or cancer.

Is My Prep Working? The bowel movement coming out should look like fluids you are drinking – clear without many particles. You know you are done when the bowel movement coming out is yellow, light, liquid, and clear, like urine.

What are the effects of the “bowel prep?” You will have lots of diarrhea from the bowel prep. This will start anywhere from a few minutes to 3 hours after you start your prep. Many people have bloating, abdominal discomfort, and/or nausea. Some people do not like the taste or smell of the medicine. Please do not let this get in the way of taking the medicine as directed.

Rarely, some people throw up while taking the prep. If you throw up, stop taking the prep for 30-60 minutes. Then try taking the prep again. If you are unable to finish the bowel prep, your colon may not be clean enough for your exam.

My prep hasn't started working yet. What do I do? Different people respond differently to the bowel prep. If you have waited more than 3 hours without a response, then it may not be working well. Be sure you are drinking enough fluid. If that doesn’t work, drink the second part of your prep and continue to drink fluids. It should work eventually. Call the UVA Endoscopy Unit at (434) 924-9999 after 8 am on the morning of your procedure if the medicine is still not working.
