A colonoscopy is one of the most effective tools for detecting colorectal cancer, polyps, and other digestive conditions early, often before symptoms even appear. While the procedure itself is quick and performed under sedation, proper preparation is essential for accurate results.
At Arizona Colorectal Experts (ACE Clinic), our board-certified colorectal surgeons, Dr. Hakiman, Dr. Patel, and Dr. Webb, are committed to making your colonoscopy experience as smooth and stress-free as possible.
This step-by-step colonoscopy prep guide will walk you through everything you need to know before your appointment at our Scottsdale or Chandler, AZ, locations.
Why Colonoscopy Prep Matters
The goal of colonoscopy preparation is to completely empty and cleanse the colon so your surgeon has a clear, unobstructed view of the colon wall. An inadequately prepped colon can obscure polyps or other abnormalities, potentially requiring a repeat procedure. Following your prep instructions carefully helps ensure:
- Accurate detection of polyps, inflammation, or early-stage cancer
- A faster, more efficient procedure
- Reduced the likelihood of needing a repeat colonoscopy
- Your safety throughout the exam
Step 1: Several Days Before Your Colonoscopy
Preparation begins several days before your scheduled appointment. Here is what to do:
Review Your Medications
Notify your ACE Clinic care team about all medications and supplements you currently take. Certain medications, including blood thinners, iron supplements, and some diabetes medications, may need to be temporarily adjusted or paused before your procedure. Your physician at ACE Clinic will provide specific instructions tailored to your health history.
Adjust Your Diet
Typically, 3 to 5 days before your colonoscopy, you will be asked to shift to a low-fiber diet. This means avoiding:
- Whole grains, seeds, and nuts
- Raw fruits and vegetables
- Legumes such as beans and lentils
- Popcorn and high-fiber cereals
Stick to easily digestible foods like white bread, plain pasta, eggs, chicken, and fish during this period.
Step 2: The Day Before Your Colonoscopy
The day before your procedure is the most important phase of your prep.
Follow a Clear Liquid Diet
You will be restricted to clear liquids only for the full day. Acceptable options include:
- Water and clear broths (chicken, vegetable, or beef)
- Plain gelatin (no red or purple dyes)
- Apple juice, white grape juice, or lemonade
- Black coffee or plain tea (no milk or creamer)
- Sports drinks like Gatorade (avoid red or purple flavors)
- Popsicles without fruit pieces
Avoid anything red or purple, as these can be mistaken for blood during the procedure.
Take Your Bowel Prep Solution
Your ACE Clinic provider will prescribe a bowel prep solution to thoroughly cleanse your colon. Common options include solutions like MoviPrep, Suprep, or MiraLAX mixed with Gatorade. Most prep protocols are split into two doses: one the evening before and one the morning of your procedure. It is important to:
- Follow your prescribed dosing schedule exactly
- Drink the solution as directed — usually in small sips over one to two hours
- Stay near a restroom after starting, as bowel movements will begin within 30 to 60 minutes
- Continue drinking clear fluids to stay hydrated

Tips to Make Colonoscopy Prep Easier
- Use flushable, pre-moistened wipes to reduce irritation
- Apply a thin layer of petroleum jelly to sensitive skin
- Drink prep solution chilled — it may be easier to tolerate
- Use a straw when drinking the prep solution
- Keep a book, tablet, or TV nearby to help pass the time
Step 3: The Morning of Your Colonoscopy
On the day of your colonoscopy at ACE Clinic:
- Complete your second dose of bowel prep if prescribed (typically 4 to 6 hours before your appointment)
- Stop all food and liquids at least 2 hours before your procedure (or as instructed)
- Arrange for a responsible adult to drive you home, as sedation will prevent you from driving safely
- Arrive at our Scottsdale or Chandler location on time with a valid photo ID and insurance information
- Wear comfortable, loose-fitting clothing
What to Expect During and After the Procedure
Your colonoscopy at Arizona Colorectal Experts typically takes 30 to 60 minutes. You will be comfortably sedated throughout, so you should not feel any pain. Afterward, you will recover briefly in a monitored area before being discharged. Most patients return to normal activities the following day, though you should plan for a quiet rest day after your procedure.
