Colonoscopy Prep is Essential

According to a study published by Shahini of the National Institute of Gastroenterology, bowel prep is considered inadequate in about 25% of colonoscopies.

Preparation is key so your doctor can get a clear view of your colon lining. The cleaner your colon the more effective the procedure is at detecting polyps or abnormalities. Skipping or skimping on prep can lead to incomplete results which may require rescheduling or in some cases repeating the procedure.

3-5 Days Before: Low Fiber Diet

A few days before your colonoscopy, start switching to a low-fiber diet to aid in bowel preparation. Reducing fiber minimizes undigested food in the colon making the final prep easier. Here’s what to focus on:

• White Bread, Rice and Pasta: Easy to digest, these refined grains leave minimal residue.
• Eggs and Lean Proteins: Go for simple proteins like chicken, fish, or turkey without the skin. Avoid fried or fatty foods.
• Well-Cooked, Skinless Vegetables: Choose vegetables like carrots, potatoes, or zucchini but make sure they’re cooked and soft.
• Dairy Products (if tolerated): Milk, cheese, and yogurt are usually okay but stick to low-fiber versions without added fruits or grains.
• Soft Fruits (without skins): Bananas, melons, and canned fruit (without skins) are nutritious and low bulk.

The Day Before your Procedure: Clear Liquid Diet

The day before your procedure switch to a clear liquid diet to complete the prep. A clear diet means no solids but here’s how you can make it varied enough to keep you energized:

• Clear Broths: Chicken, beef, or vegetable broths are perfect. Just avoid anything with solid bits to ensure effective colonoscopy preparation.
• Juices (Avoid Red or Purple): Clear apple juice, white grape juice, and sports drinks are good. Avoid anything with added coloring to ensure a successful bowel preparation.
• Plain Gelatin and Popsicles: Use these for flavor but avoid red or purple.
• Tea and Black Coffee (No Creamer or Sugar): These will give you a caffeine boost but keep it simple.
• Clear Hard Candies: Suck on a few to keep hunger at bay and stay hydrated.

Day of the Colonoscopy Procedure: Fasting and Final Prep

On the day of your colonoscopy follow your doctor’s instructions to the letter. This usually means no solid food and no liquids a few hours before your appointment.

• Stop All Food and Drink as Directed: Each provider’s timing may vary so follow the instructions you’re given.
• Sip Water (If Permitted): In some cases small sips of water are allowed but only if approved by your doctor.

Foods and Substances to Avoid

Some foods can interfere with the digestive system prep so avoid them:

• Nuts, Seeds, and Whole Grains: These foods are hard to digest and leave a residue. Avoid nuts, popcorn, flaxseeds, and whole grains.
• Raw Vegetables and Fruit Skins: Raw foods and skins are high in fiber and hard to digest so avoid salads, tomatoes, apples, and berries.
• Red or Purple Liquids: These can stain the colon making it hard to see during the procedure.
• Fatty or Fried Foods: Greasy foods can upset your stomach and make prep harder.
• Certain Medications: Medications like blood thinners, iron supplements or over-the-counter pain relievers may need to be paused. Always consult with your doctor.

Tips to Make Colonoscopy Preparation Easier

To make prep as smooth as possible:

• Stay Hydrated: Drink plenty of clear liquids the evening before your colonoscopy to avoid dehydration and keep you energized.
• Follow Instructions: Each preparation kit has specific instructions so read and follow them to avoid any surprises.
• Comfort Measures: Stock up on soft toilet paper, soothing creams, and maybe even a book. You’ll be using the bathroom a lot so it’s worth being prepared.

Colon Cleansing Kits

Here are some of the most commonly prescribed intestinal cleansing kits, each designed to help thoroughly cleanse the colon, helping to reduce the risk of colorectal cancer:

• GoLYTELY
  A powdered solution you mix with water, GoLYTELY is one of the original prep solutions. It requires drinking a larger volume of liquid but is effective in thoroughly clearing the colon. It typically comes in a one-gallon container and is flavorless, though some may prefer to chill it or add an approved flavor packet for ease.
• MoviPrep
  Known for its two-liter prep solution, MoviPrep involves drinking a smaller amount compared to traditional kits. It’s taken in two doses, generally the evening before and the morning of the procedure. MoviPrep also includes an added flavor packet for easier consumption, and many find the split-dose regimen easier to manage.
• Suprep
  Suprep is a sulfate-based prep kit that comes as a liquid concentrate mixed with water. This kit is taken in two separate doses, with each dose totaling around 16 ounces of mixed solution followed by additional clear liquids. Suprep is often considered a more palatable option due to its reduced volume compared to some of the original preps.
• Plenvu
  Designed for a low-volume approach, Plenvu requires drinking just two doses, each around 16 ounces, followed by clear liquids. It has a fruity flavor and is formulated to make the process more manageable. Many patients find this smaller-volume option easier to consume.
• CLENPIQ
  CLENPIQ is a ready-to-drink, low-volume solution that doesn’t require mixing. It’s usually taken as two doses, and no additional mixing or chilling is needed, which makes it a convenient choice for patients on the go. Its smaller volume and ready-to-drink format make it a popular choice for convenience.

Remember, each prep kit has specific instructions, so it’s essential to follow the one provided by your healthcare provider for best results.

FAQ

How does colonoscopy prep work?

Colon cleansing involves drinking a solution that helps to empty your colon by stimulating bowel movements. The solution contains a mix of electrolytes and sometimes mild laxatives that draw water into the colon, softening stool and promoting frequent trips to the bathroom.

How quickly does colonoscopy prep work?

The timing can vary depending on the prep kit, but generally, intestinal cleansing starts working within 1 to 3 hours after you begin drinking it. Some people may experience effects sooner, while others may take a bit longer. It’s best to stay near a restroom, as the prep process usually involves multiple trips.

How long does colonoscopy prep last?

Digestive system prep typically lasts several hours. The bulk of the effects may occur within the first 3 to 6 hours, but some people may continue to have bowel movements for longer, especially if they’re taking a split-dose regimen (one dose the evening before and another the morning of the procedure).

What is the easiest colonoscopy prep to tolerate?

When preparing for your colonoscopy, the easiest prep to tolerate often involves Miralax with polyethylene glycol. This one prep option requires you to stop taking certain medications and drink at least 8 glasses of a solution that makes you poop. You’ll drink another dose every one to three hours to clean out your bowels.

For those at average risk for colorectal cancer, this method helps ensure a thorough cancer screening by flushing out the rectum and intestines. Alternatively, sodium phosphate and magnesium options are available, but they may cause more discomfort.

Many find newer options like Suflave (a flavored drink) or Sutab (pills) to be more tolerable than traditional solutions.

• Suflave: Tastes like a sports drink and requires smaller volumes compared to older preps.
• Sutab: Offers a tablet-based approach, eliminating the need for consuming large quantities of liquid.
