                                According to the American Cancer Society, proper bowel preparation is the most critical factor for an accurate colonoscopy, with poor cleansing potentially leading to missed polyps. This raises a common question for many patients preparing for the procedure: can I drink a protein shake day before a colonoscopy, and what are the risks involved?
