The following information will assist you in preparing for your procedure. Please read carefully and follow the instructions closely.

If you have any questions or need to cancel your appointment, please contact our scheduling office at 651-430-8701. We are open Monday through Friday, 8am-4pm.

Please remember to arrange for a responsible adult licensed driver to accompany you home. You will not be allowed to take a taxi or other transportation service. If you do not have an adult escort your procedure will
be canceled and rescheduled. Please review the preparation schedule below for the days preceding your colonoscopy. If you need further assistance, please call our scheduling office at (651) 430-8701.


The morning of your procedure take your scheduled medications with a sip of water, unless specifically instructed otherwise. If you take medications containing fish oil, discontinue them 7 days before your appointment.

Night before your procedure

  • Do not eat after midnight.
  • You may have clear liquids until 6 hours prior to your procedure.

  • Wear loose, comfortable clothing. Leave jewelry and valuables at home.
  • You will be asked to change into an exam gown and robe.

During your procedure

  • A physician and specially trained registered nurse will be with you throughout the procedure.
  • Your throat will be numbed with an anesthetic spray.
  • Your heart rate, blood pressure and oxygen levels will be monitored.
  • You will be given medication to relax you and minimize discomfort. Be sure to let your nurse and/or physician know if you are uncomfortable so we can adjust your medication.
  • The physician may do a biopsy (taking tiny pieces of tissue from your upper intestinal tract) or a polypectomy (surrounding and burning off a polyp or small growth on the lining of your upper intestinal tract) depending on what he/she sees. Taking the specimens is painless.
  • The procedure will last approximately 10-20 minutes.
  • If you have a CPAP for sleep apnea, plan to use while napping today because of sedation medications you have received.

After your procedure

  • You will be asked to rest for approximately 30 minutes after your procedure.
  • Your family/friend will be allowed to visit.
  • The physician and/or registered nurse will discuss the results of your procedure with you.
  • If specimens were taken during the procedure they will be sent to the lab and you will be contacted with the results in 7-14 days.
  • Your nurse will review discharge instructions with you and your responsible adult caregiver and address any questions or concerns.
  • If you wish to be contacted by a registered nurse the next business day to check on how you are doing after your procedure, please provide us with a contact number (home or work).
  • After your procedure you cannot drive for the remainder of the day.
