What are the key reminders for a colonoscopy prep diet?
A colonoscopy prep diet typically starts with avoiding high-fiber foods, including raw fruits, vegetables, and whole grains, several days before the procedure. The day before the colonoscopy, patients are required to follow a clear liquid diet, including broth, clear juices, and electrolyte drinks. Laxatives may be prescribed to fully clear the colon. Following these steps ensures a successful procedure.More from NIH: Ulcerative Colitis
