Frequently Asked Questions

Scheduled Colonoscopy

  1. Dizziness and headache could be signs of low blood sugar.  Drinking a regular carbonated beverage (not diet) or apple juice may alleviate these symptoms.
  2. What is the best “clear” liquid to take? 
    Gatorade, which comes in many flavors, is an excellent choice as it contains electrolytes such as potassium.  Avoid RED/BLUE liquids.
  3. Why avoid red/blue liquids? 
    The color can persist in the colon and make an accurate diagnosis more difficult.
  4. One of the medications I was instructed to take the morning of my procedure is red.  Can I take it?
    Medication for blood pressure, heart conditions, and seizure should be taken the morning of your exam regardless of the color.
  5. Is there any way that I can make this taste better? 
    You can try sucking on hard candy.  You can rinse your mouth with water or a mouthwash.  Do not eat or drink anything other than approved liquids while you are drinking the solution.
  6. I already have diarrhea before taking the prep, do I still have to take the laxative? 
    Yes, you must take the prep as directed by your doctor.  Your colon is approximately 6 feet long.  The entire colon must be emptied for your physician to see the colon clearly.
  7. I am taking the prep and already have loose, watery stool; do I still need the rest of the prep? 
    Yes, you may have solid stool higher in the colon that needs to be eliminated.
  8. I see yellow color in the toilet bowl and a few flecks, what do I do? 
    If your last bowel movements were clear enough that you were able to see the bottom of the toilet you should be fine.  It is ok if you have some flecks of material.  The yellow color is a result of the bile that normally colors the feces.  This shouldn’t interfere with the examination.
  9. My bottom is so sore.  What can I do?
    To clean the area, avoid rubbing. Gently pat with a wet washcloth.  Apply Vaseline, Preparation H, or Desitin liberally.
  10. Can I drink alcoholic beverages? 
    We strongly suggest you do not drink any alcoholic beverages prior to your procedure since they can cause dehydration and some wines may thin your blood.
  11. Can I chew gum or suck candy? 
    Yes, but nothing with soft centers or red color.
  12. What if I am still passing stool the morning of my test?
    Take a tap water enema until you run clear.
  13. Can I brush my teeth? 
    Yes.
  14. Can I wear my dentures?
    Yes, you may wear your dentures to the Endoscopy suite.  However, you may be asked to remove them prior to the procedure.
  15. I have been instructed not to take anti-inflammatories or blood thinners several days before the procedure.  What can I take for headaches and pain relief? 
    You make take Tylenol as directed.
  16. Can I have the colonoscopy done if I am having my menstrual period? 
    Yes, the procedure can still be performed.  We ask that you use a tampon if possible (not absolutely necessary).
  17. Do I need a prescription for the laxatives? 
    It depends on the preparation instructions you were given.  Miralax is a prescription medication; Fleet’s Phospho-soda does not require a prescription.
