IMPORTANCE OF MEAL PLANNING BEFORE A COLONOSCOPY
“A man who does not plan long ahead will find trouble at his door.”
– Confucius
Planning for any goal in life helps you to withstand the hurdles that may stand in your way of that goal, and this also applies to your colonoscopy. Bowel preparation aims to produce a clean and significantly empty colon before the colonoscopy, which makes the colon’s lining easily discernable, improving the ability to detect polyps and other abnormalities.
On the other hand, poor or inadequate bowel preparation may hinder your doctor’s ability to accurately diagnose or rule out diseases, which can negatively impact your medical diagnosis and management. If you are not properly prepared, your doctor may ask you to reschedule the procedure, necessitating another round of bowel preparation. Therefore, getting it right the first time is the more convenient option.
Adequate bowel preparation is heavily centered on your diet and meal choices. Planning your meals beforehand makes completing your bowel preparation process easier. Because the recommended pre-colonoscopy diet is considerably restrictive, deciding what to eat at the last minute may be stressful, frustrating, and almost impossible. However, selecting your food options and planning your meals ahead of time can make sticking to the diet seamless and even enjoyable.
MEAL PLAN FOR 2 DAYS BEFORE COLONOSCOPY
As the date of your colonoscopy appointment draws near, the dietary regimen will become stricter. Your diet two days before your colonoscopy is more flexible than your diet a day before. However, it should also be structured to ease your transition to the clear liquid diet that commences the day of your colon exam.
COLONOSCOPY PREP 2 DAY MEAL PLAN
2 DAYS BEFORE: Two days before your procedure, you are to eat low-fiber foods like white bread, white rice, pretzels, waffles, plain pasta, well-cooked, soft, and tender white meat, e.g., skinless chicken, and so on. A low-fiber diet reduces the amount of feces formed, making it easier to tolerate the bowel movements induced by the laxatives prescribed to empty your colon.
1 DAY BEFORE: Starting from the day before reporting to the examination room, you must be on an exclusively fluid diet. From the time you start breakfast the day prior to your colonoscopy, up until your procedure, you will be required to consume only a clear liquid diet. All solid foods must be stopped, and your diet will consist of meals like chicken broth, transparent sports drinks, and clear gelatin. Therefore, as you approach the end of the second day before your procedure, it is helpful to start transitioning from low-fiber meals to clear liquid diet meals.

COLONOSCOPY PREP 2 DAY BOWEL CLEANSING TIPS
Follow Instructions Religiously
There is no room for partial adherence while preparing for a colonoscopy. Follow your doctor’s instructions on diet and medications to the letter. When in doubt, be quick to seek clarification from your care team.
Prepare Early
Unless the permitted meals are already part of your everyday diet, you will need to make special preparations including:
- Finalize plans for procuring and cooking your meals early.
- Purchase all the laxatives prescribed as early as possible.
- Start adding low-fiber and liquid foods to your meal plan 2-3 days ahead of schedule. This should make it easier to adhere to the new diet.
Clarify Laxative Instructions
Laxatives are just as important as diet to clean your colon (a.k.a. colonoscopy prep drink). The timing and dosage of the prescribed laxatives can be easily mixed up, though. Therefore, ensure you fully understand the instructions for using these drugs. Once again, communicate with your care team if you have questions.
Monitor Bowel Movements
Your bowel movements can provide key insights into how well your bowel cleansing process is going. As you change your diet and use laxatives, the consistency of your stool should gradually change from solid and well-formed to watery and loose. Similarly, the color should become lighter with each movement till it is yellowish. If these changes are not occurring, it might be a sign that bowel preparation is not optimal.
CONCLUSION
With two days left to your colonoscopy appointment, it is time to start making major dietary adjustments. Planning out your meals is important to help you cope with and adhere strictly to the bowel-cleansing diet. Following a low-fiber diet might be new to you, but you cannot go wrong following the structured meal plan shared above.
