1-Week Colonoscopy Diet Sheet

‍

Here’s what you can eat and what you must avoid one week before a colonoscopy:

‍

1. Focus on low-fiber foods

A low-fiber diet helps ensure that your colon is clear of any residues. Here are some low-fiber choices [1]:

  • Lean proteins: Chicken, turkey, and fish
  • Low-fiber fruits: Very ripe bananas and apricots, canned peaches, and watermelon
  • Cooked vegetables: Carrots and green beans, well-cooked and peeled
  • Clear broths: Chicken, beef, or vegetable broth without any particles or fat

‍

Contrary to popular belief, although salmon is a fatty fish, its fat is mostly unsaturated, which is beneficial for heart health—especially due to the Omega-3 fatty acids it’s rich in. Additionally, salmon is naturally free of carbohydrates and contains no fiber.

‍

Avoid raw vegetables, nuts, and seeds. They can be hard for your digestive system to process [1].

‍

2. Stay hydrated

Drink plenty of fluids to stay hydrated and keep your intestines clear for a colonoscopy. You can have water, clear juices like apple or white grape, broths, carbonated drinks, or coffee and tea without creamers [2].

‍

You don't have to just drink water to stay hydrated. You can also get plenty of water from foods like watermelon, cucumbers, beets, carrots, and celery.

‍

3. Avoid dairy

Dairy products like milk and milk powder can leave traces in your gut. This can hide parts of your colon lining and affect your results [3].

‍

Anything that you drink other than clear liquids can end up inside the colon. Traces of milk can hide a possible polyp in the walls of the colon.

‍

4. Avoid foods with red or purple dye

Red or purple dyes can stain the colon and interfere with the colonoscopy results. Stay away from red or purple juices, sodas, jellies, candies, and sauces [2].

5. Avoid tough meats and high-fat foods

Avoid eating fatty cuts of meat (ribeye steak, bacon, and sausages) and fried foods (fried chicken, fries, and chips). These can be hard on your digestive system as they take longer to digest [4].

You’ll also need to stop taking iron and vitamin E supplements, blood thinners, and pain relievers. Additionally, avoid drinking alcohol, as these can interfere with your colonoscopy results [2, 3].

‍Two Days Before Your Colonoscopy

Follow a clear liquid diet two days prior and avoid solid foods to ensure your colon is empty for a thorough examination. This includes consuming clear broths, clear juices like apple or white grape, plain water, and popsicles [2. 5, 6].

On the night before the procedure, avoid eating or drinking anything, including water, after midnight [6].

Begin Your Laxative Prep

You’ll have to take laxatives two days before your colonoscopy. This is crucial for cleansing your bowels before the procedure. If you’re choosing between colonoscopy prep pills vs. liquid, consult your doctor to determine the best option for you [6].

‍

You'll need to start taking laxatives two days before your colonoscopy to ensure your bowels are properly cleansed.

‍

Post Colonoscopy Diet

After your colonoscopy, eat soft and easy-to-digest foods such as mashed potatoes, white fish, applesauce, gelatin, soft fruits, and cooked vegetables [7].

Using a Stool Test Kit: Why It Matters

Before scheduling a colonoscopy, consider using a stool test kit like Diagnox’s Colonox fecal immunochemical test (FIT). This at-home test helps detect any lower gastrointestinal bleeding, which could indicate conditions like fissures, polyps, hemorrhoids, or cancer. Early detection can help you and your doctor address potential issues before a colonoscopy [8] [9].

For your peace of mind, use a stool test kit like Diagnox’s Colonox FIT to detect issues early from the comfort of your home. Be fully prepared — order Colonox FIT today and take charge of your gut health.

Frequently Asked Questions

Still have questions? Here are some common concerns about colonoscopy preparation and at-home testing:

Why is a low-fiber diet recommended before a colonoscopy?
A low-fiber diet helps reduce the amount of waste in your colon, making it easier for the doctor to get a clear view during the procedure. It minimizes residue and ensures that the bowel is properly cleaned out.

Can I drink water during the clear liquid diet phase?
Yes, staying hydrated is crucial. During the clear liquid diet phase (typically the day before your colonoscopy), you can drink water, broth, clear juices, and other transparent liquids, but avoid any drinks with artificial coloring.

How can at-home testing like the Colonox FIT kit help before a colonoscopy?
The Colonox FIT kit helps detect hidden blood in your stool, which could indicate potential issues in your gastrointestinal tract. It’s a useful tool for identifying concerns early, giving you and your doctor valuable information before undergoing a colonoscopy.
