Frequently Asked Questions About Colonoscopy

  • A: No. To ensure your safety during the procedure, it is important that the stomach is empty. Any food or liquid in the stomach at the time of the procedure places you at risk of aspirating those contents into the lung leading to a serious complication called aspiration pneumonia. You can drink water until 4 hours before your procedure time.

  • A: If the preparation instructions were not followed properly, residual stool may remain in the colon and hide important findings from the examining physician. In some cases if the colon preparation is not good, you may have to repeat the preparation and the exam. If you accidentally eat any solid food the day before your exam, please call and ask to speak with a member of the nursing staff. You may be asked to reschedule your procedure.

  • A: No. If you do not have a responsible adult to accompany you home, YOUR PROCEDURE WILL BE CANCELLED.

  • A: If you are taking any blood thinning medications please let your endoscopist know. Generally speaking, you should quit taking your blood thinning medication 5-7 days prior to some procedures; however, you must check with your endoscopist and your prescribing physician to ensure that it is needed and safe for you to do so.

  • A: The day prior to your procedure take your medications the way you normally would. However, for those patients taking any type of bowel cleansing preparation, be advised that you may undergo a prolonged period of diarrhea that may flush oral medications out of your system before they have time to take effect. The morning before your procedure you should take any blood pressure or heart medications you may be on with a small sip of water. You can hold most other medications and take them once your procedure has been completed. If you have questions about a specific medication(s), please call a member of our clinical staff.

  • A: You must direct that question to the physician who placed you on this medication. Please check your blood sugar the morning of your procedure as you normally would. If you have any questions about your diabetes management in conjunction with your fast for your endoscopic procedure, please consult with your primary physician.

  • A: Many prescription pain medications can adversely affect the medications we use for sedation and for that reason we recommend that the day of your procedure you delay taking your pain medication until after your procedure has been completed. If you have any questions, please call a member of our clinical staff.

  • A: No. Your menstrual period will not interfere with your physician’s ability to complete your procedure.

  • A: No. Iron may cause the formation of dark-colored stools which can make it difficult for the physician to complete your colonoscopy if your preparation is less than optimal. We recommend you stop taking your oral iron supplements at least one week prior to your procedure.

  • A: Aspirin may affect blood coagulation. Please check with your endoscopist and prescribing physician.

  • A: Nausea, vomiting and a sense of fullness or bloating can occur any time after beginning your colon preparation. However, it is important that you drink all the preparation. For most people, taking an hour break from the preparation will usually help. Then continue taking the preparation as ordered. If the vomiting returns or symptoms get worse, please call your physician.
