Dark yellow stool or liquid may be considered borderline acceptable for a colonoscopy, but clear or light yellow is the ideal target. The clarity and color of bowel movements prior to the procedure are critical because they indicate how clean your colon is. A too-dark color could obscure the view during the colonoscopy, potentially missing important signs or conditions. To achieve the best results, follow the bowel preparation guidelines given by your healthcare provider, which typically include consuming only clear liquids and avoiding certain foods and dyes.
