Most people have a colonoscopy procedure starting around age 50. It’s important to follow the prep instruction for the colonoscopy before the procedure. This article shares ideas and guidelines for what to eat after a colonoscopy including a food list and recipes.

What is a Colonoscopy?

A colonoscopy is a procedure performed by your healthcare provider to examine the inside of your large intestine, which is made up of your colon and rectum. 

During the medical procedure, a long, thin instrument called a colonoscope is passed into your colon. The colonoscope is a flexible tube that carries a camera and is also able to remove tissue from inside the intestine (although you won’t feel it due to the anesthesia that you will likely have before the test).

The purpose of the test is to look for any issues that may be causing bowel problems such as pain in the abdomen, bleeding, or persistent diarrhea. 

The test can be used to diagnose all sorts of conditions of the digestive tract, from ulcerative colitis and Crohn’s disease to colorectal polyps and colon cancer. 

The procedure may also be offered as a routine screening test for colorectal cancer or colon health once you reach the age of 50. See my list of the best lab tests for women.

A colonoscopy is usually performed while you are awake, but you are sedated to keep you relaxed. Although you might feel the tiny camera going in – and experience a little bloating when air is pumped into the intestine to help your doctor see your colon walls more clearly – you shouldn’t feel any pain.

Before your colonoscopy, your healthcare provider will give you instructions on how to clear out your colon (known as a bowel prep which will result in a bowel movement). This prep is very important, as your doctor needs to see the walls of your colon clearly and even small amounts of residue could make it hard to spot any abnormalities. 

Part of the process of emptying your colon and digestive system will involve eating only certain foods. Be sure to follow your doctor’s recommendation for what to eat before a colonoscopy.

Foods to Eat Before a Colonoscopy

Whilst your healthcare provider will give you specific instructions, it is usually recommended that you only eat plain foods two days before a colonoscopy.

Foods you can generally eat before a colonoscopy include:

  • white bread, rice, or pasta
  • cookies made with white flour (avoid any with nuts, seeds, or dried fruit)
  • low fiber cereals
  • plain meat (avoid sauces)
  • cooked or canned vegetables with no skin or seeds (but avoid corn, tomatoes, cabbage, Brussels sprouts, peas, squash, lima beans, and onions)
  • smooth nut butters
  • butter, margarine, mayonnaise, and vegetable oils
  • clear soups, or strained milk-based soups
  • custard, ice cream, plain pudding, sorbet, or sherbert
  • Jell-O (with no added fruit – avoid any containing purple or red dye)
  • drinks such as coffee, tea, hot chocolate, soda, fruit drinks or fruit juice (without pulp)

Your doctor will probably recommend that you don’t eat any solid foods at all the day before the colonoscopy. You are allowed to drink, but only certain types of drinks – usually clear liquids – are suitable. 

Drinks generally okay to consume before a colonoscopy include:

  • plenty of water
  • black tea, herbal teas, and coffee (do not add milk or cream)
  • carbonated drinks
  • clear broths

Avoid drinking anything purple or red, as it can be mistaken for blood during the procedure.

You may be advised not to eat or drink anything at all after midnight the night before the exam.

Foods to Eat After a Colonoscopy

Once the colonoscopy is over, you need to make sure you replenish your stores of electrolytes and fluids, as the procedure is quite dehydrating.  

Along with having plenty of fluids, your doctor will probably recommend that you have some fluid-based foods, and may suggest a soft, low-residue diet. This will include dairy and foods low in fiber because they are easy to digest and therefore gentle on your colon. 

Try to keep meals light and frequent, rather than eating a lot in one go.

Good foods and drinks to choose from after a colonoscopy include:

  • water
  • electrolyte drinks or sports drinks
  • herbal tea
  • bone broth
  • fruit or vegetable juices
  • yogurt or other dairy products
  • scrambled eggs
  • soup
  • white fish
  • pudding
  • applesauce
  • graham crackers

See my recipes for Instant Pot Vegetable Broth, Crockpot Applesauce, or my list of anti-inflammatory vegetable juices. I also have a whole index of healthy soups and stews that you can choose from.

Essentially, for at least the first day after the procedure, you’ll want to focus on light meals with bland foods that are easy on your system.

Steer clear of things that are hard to digest and likely to make you feel bloated or gassy, such as:

  • nuts, seeds, or popcorn
  • spicy foods
  • corn or beans
  • broccoli, cauliflower, or cabbage
  • garlic
  • alcohol
  • fried food or other fatty foods
  • tough, gristly meat
  • high-fiber foods

You can also ask your doctor what he or she specifically recommends eating after a colonoscopy. You may also be advised to rest and take it easy for a day or two after the procedure.

As long as you give yourself some time to recover, you should be able to eat normally and perform normal activities within a day or so.

Best of all, you’ll know that you’ve gotten through your colonoscopy and you can pat yourself on the back for getting through it.

Can I eat whole grains after a colonoscopy?

Whole grains are a good source of fiber, which is beneficial for your digestive health. However, immediately after a colonoscopy, your digestive system may be sensitive or inflamed, and high-fiber foods can sometimes be harder to digest. Therefore, it is often advised to start with low-fiber foods and gradually increase the fiber content over a few days.

Typically, a clear liquid diet is recommended in the immediate post-colonoscopy period, followed by a low-fiber diet for a few days.

Once you have successfully transitioned to a low-fiber diet without any complications, you can begin introducing whole grains slowly. Examples of whole grains include whole wheat bread, brown rice, whole grain bread, quinoa, oatmeal, and whole grain pasta. White rice may be easier to digest than brown rice.

Can I eat fruits and vegetables after a colonoscopy?

The timing for reintroducing fruits and vegetables after a colonoscopy may vary depending on individual circumstances and the instructions provided by your healthcare provider.

Initially, you may be instructed to avoid raw fruits and vegetables, as they are high in fiber and can be more challenging for your digestive system to handle immediately after the procedure. Instead, you may be encouraged to consume cooked or canned fruits and vegetables, which are typically easier to digest.

How long should I follow a modified diet after a colonoscopy?

The duration of the modified diet after a colonoscopy can vary depending on factors such as the reason for the procedure, any findings or interventions during the colonoscopy, and individual factors. It is essential to follow the specific instructions and recommendations provided by your healthcare provider.

In many cases, a modified diet is followed for a short period to allow the digestive system to recover. The immediate post-colonoscopy period often involves a clear liquid diet, followed by a gradual reintroduction of low-fiber foods. This phase typically lasts for a few days to a week, but it can vary.


Some people feel a little intimidated at the thought of a colonoscopy, but it is an important procedure to have as it can spot early signs of potential problems or help diagnose anything that’s currently causing you discomfort. Eating foods that are kind to your bowel for the next couple of days will help you recover quickly, so you will soon be back to enjoying your regular diet.
