Procedures and Preparations


Colonoscopy is recommended as preferred screening for everyone over the age of 50 with average risk of colon cancer. This procedure allows your doctor to examine the entire colon (large intestine) to remove polyps and take sample of tissues (biopsy) to look for signs of cancer. The colonoscopy and tissue examination allows your doctor to find answers for problems such as diarrhea, rectal bleeding, anemia, abnormal x-ray studies and unexplained alteration of bowel habits.

The procedure is done with intravenous sedation or mild anesthesia to help you relax and relieve any discomfort associated with the examination. You will be lying on your left side with your knees bend toward your chest. The colonoscope, a thin flexible scope with camera and light transmitting images to a video monitor, will be inserted in your rectum and gently advanced into the colon to the cecum. The procedure generally takes less than 30 minutes. However, allow yourself to be at the endoscopy center for a total of 2 hours to adequately recover from the procedure and sedation.


colon needs to be cleaned thoroughly to facilitate a thorough examination. You will be given a specific “bowel prep instructions” depending on your bowel habits and other medical conditions. You will experience significant diarrhea with your prep, so stay near a bathroom. Please click this link Suprep for our standard bowel prep instructions. Other bowel cleansing medications such as Plenvu, Clenpiq, MoviPrep and PEG-3350 maybe use as an alternative.

If you are on medications that can lead to excessive bleeding, such as Coumadin, Eliquis, Xarelto and Pradaxa, please check with your prescribing doctor to assist with instructions on holding the medication for 1 to 3 days prior.

If you are taking Iron replacement, you need to hold it 7 days before unless otherwise directed.

For patients taking diabetes medications, please click this link DM prep for your specific instructions.

If possible, avoid or minimize eating the following food items 7 days before your exam:

  • Popcorn
  • Nuts
  • Poppy
  • Watermelon
  • Cucumbers
  • Tomatoes
  • Celery
  • Seaweed

You will be given a copy of your colonoscopy report and discharge instructions before leaving the endoscopy center. Someone must drive you home. We will not be able to perform your procedure if you do not have an available driver to take you home.
