What to Eat After Colonoscopy: Your Comprehensive Guide


A colonoscopy is a medical procedure that allows doctors to examine the lining of the colon for any abnormalities or signs of diseases such as colon cancer. After the procedure, patients need to follow a special diet to give their digestive system time to heal. In this article, we will provide you with a comprehensive guide on what to eat after colonoscopy.

What to Eat After Colonoscopy

Liquid Diet

For the first 24-48 hours after a colonoscopy, patients are advised to follow a clear liquid diet. This includes water, broth, tea, apple juice, ginger ale, sports drinks, and ice pops. These fluids will keep you hydrated and help prevent constipation.

Low-Fiber Foods

After the liquid diet, patients can start incorporating low-fiber foods such as white bread, crackers, pasta, white rice, skinless chicken, tofu, and fish. These foods are easy on the digestive system and provide the necessary nutrients while allowing the colon to heal.

Fiber-Rich Foods

After a few days, patients can gradually add high-fiber foods to their diet. These include fruits, vegetables, whole grains, and beans. It is essential to increase fiber intake gradually to prevent any discomfort or digestive issues.


Probiotics are beneficial bacteria that live in the gut and help maintain digestive health. After a colonoscopy, it may be helpful to consume probiotics such as yogurt, kefir, sauerkraut, and kimchi to restore the gut's natural balance.


It is crucial to drink plenty of fluids after a colonoscopy to help prevent dehydration and constipation. Aim to drink at least 8-10 cups of water a day and avoid caffeinated or alcoholic beverages.

What to Avoid After Colonoscopy

There are certain foods that patients should avoid after a colonoscopy to prevent digestive issues and discomfort. These include:

  • Spicy foods
  • Raw vegetables and fruits with skin or seeds
  • Nuts, popcorn, and other hard-to-digest snacks
  • Fatty or greasy foods
  • Dairy products, especially if lactose intolerant
  • Carbonated beverages


1. When can I start eating solid foods after a colonoscopy?

After the liquid diet, patients can start incorporating low-fiber solid foods. It is essential to consult with your doctor before resuming your regular diet.

2. Can I drink coffee after a colonoscopy?

3. How long should I follow a special diet after a colonoscopy?

The length of the special diet depends on each patient's individual recovery. It is essential to follow the doctor's instructions and gradually introduce new foods.

4. What if I experience diarrhea or stomach pain after a colonoscopy?
