Dietary Guidelines Handout

Beginning ONE WEEK PRIOR to your procedure you will start a Low-Fiber and Low-Residue Diet. It is important to avoid high-fiber and high-residue foods the week leading up to your procedure. Following this diet helps to ensure your colon is as clean as possible, so the physician can clearly see the lining of your colon. If you do not follow this guidance, your colon may not be adequately cleared which may greatly impact the
quality of your prep. We may recommend repeating your procedure if the physician feels the quality of the procedure is inadequate based on poor bowel prep.

Beginning 1-3 DAYS PRIOR to your procedure you will start a Clear Liquid Diet. Review your procedure instructions for the exact day and time to start your clear liquid diet. Additionally, reference the clear liquid diet handout for dietary advice and restrictions for this period of your bowel preparation. If you did not receive these handouts, please contact our office.

  • "From my first phone call to his office and subsequent video conferencing with Dr. McClendon did I realize that I had got the right Doctor. My interaction with his staff and him were amazing. For a person that is anxious and reluctant to go to doctors, they made me feel at ease."
