5 Colonoscopy Prep Mistakes to Avoid for Accurate Results

A colonoscopy is a crucial procedure for diagnosing and preventing colorectal diseases, including cancer. As common as it is, many patients inadvertently hinder the process by not following preparation instructions to the letter. Here are five things gastroenterologists wish you wouldn't do before a colonoscopy to ensure the procedure goes smoothly and yields the most accurate results.

1. Not Following the Bowel Preparation Instructions Exactly

The Importance of a Clean Colon

A clean colon is essential for a successful colonoscopy. If your colon isn’t properly cleansed, the doctor might miss polyps, lesions, or other abnormalities. This could lead to an incomplete procedure, necessitating a repeat examination. Inadequate preparation can also prolong the procedure, increasing the risk of complications.

Common Mistakes

• Skipping Dosages: Some patients skip the second dose of the bowel prep solution, thinking the first dose was sufficient. However, the second dose is equally crucial to ensure the colon is thoroughly cleaned.
• Not Drinking Enough Clear Fluids: Staying hydrated during the bowel preparation phase helps flush out the system. Patients often under-consume fluids, leading to inadequate cleansing.
• Ignoring Dietary Restrictions: Following the prescribed low-fiber diet before starting the bowel prep is vital. High-fiber foods can obstruct the view of the colon wall during the procedure.

2. Eating Solid Foods the Day Before the Procedure

Why Solid Foods are a Problem

Consuming solid foods the day before a colonoscopy can leave residues in your colon, obstructing the view and potentially leading to missed diagnoses. Even a small amount of solid food can impair the bowel cleansing process.

What to Do Instead

• Clear Liquid Diet: Stick to a clear liquid diet, including water, broth, clear juices, and gelatin (avoid red and purple colors, as they can be mistaken for blood).
• Avoid Alcohol and Dairy: Alcohol can dehydrate you, complicating the preparation process, while dairy products can leave residues in the colon.

3. Failing to Inform Your Doctor About Medications and Supplements

Medication Interactions

Certain medications and supplements can interfere with the colonoscopy or the preparation process. Blood thinners, for instance, can increase the risk of bleeding during polyp removal, while iron supplements can darken the stool and make it harder to see inside the colon.

What to Communicate

• All Medications: Inform your doctor about all the medications you are taking, including over-the-counter drugs and supplements.
• Adjustments: Your doctor may advise you to stop taking certain medications or adjust dosages in the days leading up to your colonoscopy.

4. Not Arranging for a Ride Home

Why You Need Assistance

A colonoscopy involves sedation, which impairs your ability to drive or operate machinery for up to 24 hours post-procedure. Despite knowing this, many patients fail to arrange for transportation, causing logistical issues and safety concerns.

Plan Ahead

• Designate a Driver: Ensure a friend or family member is available to take you home.
• Public Transportation or Ride Services: If you cannot find someone to drive you, consider using a taxi or ride-sharing service.

5. Ignoring Health Changes Before the Procedure

Health Changes and Their Impact

If you experience new or worsening symptoms like fever, severe abdominal pain, or changes in your overall health status, it’s critical to inform your doctor. Such changes could affect the safety and timing of your colonoscopy.

What to Monitor

• New Symptoms: Any new or worsening symptoms should be reported.
• Existing Conditions: Conditions like diabetes or heart disease may require special preparation instructions.

Additional Tips for a Successful Colonoscopy

• Stay Informed: Thoroughly read all preparation instructions provided by your healthcare provider.
• Hydrate: Drink plenty of clear fluids before, during, and after the bowel preparation process.
• Ask Questions: If you’re unsure about any part of the preparation, don’t hesitate to contact your doctor.

By avoiding these common pitfalls, you can help ensure your colonoscopy is as effective and smooth as possible. Proper preparation not only facilitates a more accurate diagnosis but also contributes to your overall comfort and safety during the procedure.
