A colonoscopy is an important diagnostic procedure, but recovery does not end when the test is over. Knowing what to eat after a colonoscopy plays a major role in how quickly your digestive system settles and how comfortable you feel afterward. The bowel prep and sedation can temporarily disrupt digestion, hydration, and energy levels.
This article explains what to eat after a colonoscopy step by step. You will learn which foods support fast recovery, which foods to avoid, how to ease bloating, and how to return to your normal diet safely.
