If you’re dreading your upcoming colonoscopy, you’re not alone. For many, the hardest part of the procedure isn’t the colonoscopy itself, but the prep work leading up to it. The idea of fasting, drinking potent laxatives, and spending hours running to the bathroom can feel overwhelming. However, there’s good news preparing for a colonoscopy has become easier and more manageable over the years.
As Dr. Catherine Cheney, a gastroenterologist at Beth Israel Deaconess Medical Center, notes, “Things have changed a lot in the past 10 years.” Medical advancements have introduced low-volume preps that are much easier to tolerate and medications to reduce nausea. These improvements have made the process more bearable for many patients.
Why is Colonoscopy Prep Important?
The preparation phase is critical for ensuring a successful colonoscopy. A clean colon provides your gastroenterologist with a clear view of the bowel, allowing them to detect and remove any polyps small growths that could eventually develop into cancer. Colon cancer is the second leading cause of cancer-related deaths in women, but with proper screening, it can often be detected early, saving lives. A thorough colonoscopy ensures that any polyps or early cancers are spotted before they have a chance to spread.
What Does Colonoscopy Prep Involve?
The goal of the prep is to empty your colon completely. While different medical centers may offer slightly different instructions, the general process typically follows these steps:
- A few days before your appointment: Switch to a low-fiber diet. Avoid foods like whole grains, seeds, nuts, dried fruit, and raw fruits and vegetables, as these can leave residue in your colon.
- The day before the procedure: You’ll need to refrain from eating solid foods. Stick to clear liquids such as clear broth, tea or coffee (without milk), apple juice, clear sports drinks, and Jell-O. Avoid red or purple-colored liquids, as these can interfere with the procedure.
- The afternoon or evening before the colonoscopy: Drink the first dose of the prescribed laxative solution. The timing and specifics of the prep will depend on your doctor’s instructions, but the goal is to get your colon as clean as possible before the procedure.
- The day of the colonoscopy: Continue with clear liquids only. Stop drinking anything at least two hours before the procedure.
- Six hours before your appointment: Take the second dose of the prep. The American Gastroenterological Association recommends splitting the dose, as it cleans the colon more thoroughly and helps avoid lingering fluids that could interfere with the procedure.
Throughout the entire prep period, remember to stay hydrated. Drinking plenty of fluids will help flush the bowel while maintaining your electrolyte balance, which is essential during this process.
Special Considerations
For some patients, the preparation process may need to be adjusted. For instance, people with chronic constipation may have a longer colon that’s more difficult to empty. In these cases, your doctor might recommend a two-day prep. Those with specific medical conditions, such as kidney disease or heart problems, may need a modified prep to avoid certain substances like phosphates or magnesium.
If you’ve had a failed prep in the past or had difficulty tolerating the laxatives, talk to your doctor. They can prescribe a different regimen that’s more likely to work for you.
Making the Process More Comfortable
If nausea or the taste of the laxative is a major hurdle, you’re not without options. Dr. Cheney suggests that taking an anti-nausea medication like ondansetron (Zofran) an hour before the first dose and every six to eight hours during the prep can make the process more manageable for many patients.
Remember, the discomfort is temporary, and the benefits of a clean colon far outweigh the inconvenience of prep. Colonoscopy can help prevent cancer and detect potential issues before they become serious, so while the preparation may not be enjoyable, it’s an essential part of taking charge of your health.
While the idea of colonoscopy prep may seem daunting, it doesn’t have to be. With modern advancements in medication and prep options, you can approach your procedure with greater ease. So, follow your doctor’s instructions, stay hydrated, and remember that the procedure could potentially save your life.
