COLONOSCOPY INSTRUCTIONS

Special considerations for patients on blood thinning medications

If you are on a blood thinning medication(s) please contact your prescribing provider and make sure you can stop them before your procedure. We will provide you with information about our preferred timeline for stopping these medications before the colonoscopy. 

Special considerations for patients on diabetes medications

If you are on a diabetes medication please contact your provider who manages this medications for guidance on managing these medications prior to your procedure. 

Eating and drinking instructions for STANDARD bowel prep - NOT applicable for EXTENDED bowel pre

7 Days Before Your Procedure:

Avoid high fiber foods (you will be provided a list of these foods)


1 Day Before Your Procedure:

-Do NOT eat solid foods. 

-Drink only "clear" liquids. These include water, apple juice, clear fat free broth, carbonated beverages, sports drinks and coffee (without milk or dairy products), and ice popsicles (without miilk). 

-Start your Bowel Prep at the designated time (provided by our staff).  Bowel prep instructions are included on this page for your reference (see PDF files below under DOWNLOADS). 


Day of the procedure:

-Stop drinking clear liquids at least 2 hours before your procedure.

-If you take a daily medication, you may take this with sips of water before your scheduled arrival time


After Your Colonoscopy

1. Because you are receiving moderate sedation, you must have an adult (18 years or older) accompany you home. The driver must be flexible as the procedure may run longer than expected.

If you do not have a ride, we cannot do the procedure with sedation.

2. The person driving you must accompany you at check in for confirmation and instructions for pick up.

3. You should not plan to work, schedule other appointments or meetings following your procedure. You should not drive for the remainder of the day.

4. After your procedure is completed, you may experience some cramping or bloating because of the air introduced into the colon during the examination. This should settle down with the passage of gas.

5. Generally you should be able to eat after your procedure, but your doctor may restrict your diet and activities, especially if a polyp was removed. 


Helpful Hints

1. You should be prepared to be near the bathroom during this preparation. The laxative can take effect within 1‐4 hours.

2. The laxative will cause you to have very loose, watery stools. That is the goal. Take the entire laxative to be sure your colon will be well prepped for viewing.

3. Consider having a soothing cream such as Vaseline, A&D, or Desitin cream available to reduce irritation from frequent bowel movements.

4. Please pay close attention to the directions concerning what you should and should not eat and drink to avoid having to reschedule your procedure.

5. You should allow enough time for the laxative to finish working before traveling
