Can I eat normally 5 days before colonoscopy?

Many people wonder if they can eat normally in the days leading up to a colonoscopy. The preparation for a colonoscopy typically involves strict dietary restrictions starting 1-3 days beforehand. However, in the 5 days prior to that, most patients can continue with a relatively normal diet.

What is a Colonoscopy?

A colonoscopy is a procedure in which a doctor uses a colonoscope (a thin, flexible tube with a camera) to examine the rectum and entire colon. It allows the doctor to look for polyps, cancers, ulcers, and other abnormalities.

In order to get a clear view, the colon must be completely empty of stool. To achieve this, patients follow a preparation of laxatives and dietary restrictions to clean out the bowels beforehand. The preparation clears out any solid material so the doctor can thoroughly examine the colon lining during the procedure.

Typical Colonoscopy Preparation Timeline

The preparation process typically begins 1-3 days before the colonoscopy. Here is a typical timeline:

  • 5 days before: Continue with normal diet
  • 3 days before: Stop eating high-fiber foods, seeds, nuts, quinoa, popcorn, raw vegetables
  • 2 days before: Only eat light foods like eggs, white bread, chicken, fish, yogurt, cheese
  • 1 day before: Clear liquid diet only – water, clear broth, apple juice, black coffee, gelatin
  • Day of colonoscopy: No eating or drinking 2-4 hours beforehand

However, timelines can vary based on your doctor’s recommendations. Some preparations may start 2-4 days before instead. The key is to follow the specific instructions from your doctor.

Can I Eat Normally 5 Days Before?

Yes, in most cases you can eat a normal diet in the 5 days leading up to the colonoscopy prep. This allows you to get good nutrition before you have to restrict your diet.

During those 5 days, you should be able to eat your regular foods, including:

  • Grains like bread, pasta, cereal
  • Fruits and vegetables
  • Dairy products like milk, cheese, yogurt
  • Protein foods like meat, poultry, fish, eggs, beans
  • Fats and oils
  • Sugary foods like chocolate, cookies, cake in moderation

Eat normal portion sizes of a balanced diet. Avoid overeating or eating too much junk food, as you want to prevent constipation during this time.

Stay well hydrated by drinking lots of water, juice, tea, etc. Proper hydration will help the preparation work better.

Foods to Avoid Close to the Colonoscopy

In the 3 days before, you’ll need to cut out high-fiber foods like:

  • Whole grains – whole wheat bread, brown rice, bran cereals
  • Fruits and vegetables with skins, seeds or membranes – berries, pineapple, tomatoes, corn, beans
  • Tough stems and stalks – broccoli, celery, asparagus
  • Dried fruits
  • Nuts and seeds
  • Popcorn

Fiber can leave residue in the colon and make it harder to get a clear view. Avoid anything that could leave behind undigested particles.

In the 2 days leading up, switch to light, low-fiber foods that are easy to digest like eggs, yogurt, white bread, chicken, fish, etc. This gives your colon a bit of a rest beforehand.
