After a colonoscopy, you can typically start eating soft, bland foods and drinking liquids right away, but it's best to start with light, easy-to-digest foods and increase intake gradually. Generally, you should avoid solid foods for the first 1 to 2 hours immediately after the procedure and start with clear liquids first. Most people can return to their normal diet within 24 hours unless polyps were removed, in which case special instructions may apply. It is also important to stay hydrated and avoid alcohol, caffeine, carbonated drinks, greasy, spicy, or high-fiber foods initially to allow the gastrointestinal system to recover comfortably.
Eating Timeline After Colonoscopy
- First 1-2 hours: Clear liquids only (e.g., water, broth, electrolyte drinks).
- Hours after: Soft, bland foods such as mashed potatoes, white rice, cooked vegetables, peeled fruits, and yogurt.
- Within 24 hours: Most can resume regular eating gradually.
- If polyps were removed: Follow doctor's guidance for a more restrictive diet.
Foods to Avoid Initially
- Alcohol, caffeine, and carbonated drinks.
- Fast food, high-fat, greasy, and spicy foods.
- Raw vegetables, whole grains, nuts, seeds, and tough meats.
The key advice is to "take it easy" on the digestive system and listen to your body's response, starting small and increasing food intake as tolerated.
