However, sometimes these changes can be a sign of an underlying medical condition that requires further evaluation.emen is normally a whitish-gray color.

TWO-THREE Days BEFORE THE COLONOSCOPY-Do not eat beans, peas, corn, nuts, popcorn, okra, or tomatoes 2-3 days prior to your colonoscopy, as the seeds of these foods may adhere to the intestinal wall and may not flush out with bowel prep (start now if your colonoscopy is scheduled within the next 3 days).WO-THREE Days BEFORE THE COLONOSCOPY-Do not eat beans, peas, corn, nuts, popcorn, okra, or tomatoes 2-3 days prior to your colonoscopy, as the seeds of these foods may adhere to the intestinal wall and may not flush out with bowel prep (start now if your colonoscopy is scheduled within the next 3 days).
How you prepare. Before a colonoscopy, you'll need to clean out (empty) your colon. Any residue in your colon may obscure the view of your colon and rectum during the exam. Follow a special diet the day before the exam. Typically, you won't be able to eat solid food the day before the exam. Drinks may be limited to clear liquids â plain water, tea and coffee without milk or cream, broth, and carbonated beverages. Avoid red liquids, which can be confused with blood during the colonoscopy.
