What is a Colonoscopy?

Before we dive into whether or not you can consume oats pre-colonoscopy, let’s quickly go over what exactly a colonoscopy entails. A colonoscopy is a procedure used by doctors to examine the lining of the large intestine (aka the colon) using a long, flexible tube with a camera at its end called a colonoscope.

The main purpose of having this test done is to check for signs of abnormalities such as polyps or tumors that could potentially turn malignant if left untreated.

Preparing for Your Colonoscopy

Now, hold up just one second before you start digging into those delicious oatmeal cookies… unfortunately, certain foods are off limits in preparation for your impending exam. In order for your doctor to get an accurate view of your intestinal walls during the procedure, they will ask that you follow some dietary restrictions prior to coming in.

This includes avoiding solid foods and switching over to liquids-only starting from 24 hours before the exam itself. Some typical examples of approved items include:

  • Clear broth
  • Jello
  • Ice popsicles
  • Apple juice

But wait…can’t I have oatmeal? After all it’s mushy just like oat porridge– which means my grains requirement every morning would still stay unscathed!

Well…not exactly.

The Deal With Oats

While consuming oats isn’t explicitly bad per se; since most other whole-grain options aren’t allowed at this time due fiber content—oatmeal specifically isn’t recommended because it contains bits of oat bran and fiber that could get lodged along the intestinal walls.

This makes getting a clear image of the internal condition difficult during examination by obscuring parts of colon through which doctor s have to identify any harmful formations.

So, you might be thinking: “But I’ve had oats before my last colonoscopy and everything was fine!” It’s important to keep in mind that every person’s body is different; hence some medical practitioners would likely hold differing opinions. However, when preparing for a new colonoscopy—it’s best not to take chances as this can set your progress back.

What Should You Eat Beforehand?

That being said, there are plenty of other options available! For starters it’s better described with what one shouldn’t eat rather than what they can in the days leading up to their exam. Ideally NO food containing nuts, seeds, or kernels should be consumed at least 7 days prior since they contain elements difficult for digestive enzymes processes & pass out easily undigested products. Along with these offenders alcohol must also go off your menu for few days–as letting them stay on plate while expecting effective results from exams like Colonoscopies sounds pretty naive!

While having rest beverages choices include:

  • Clear broth
  • Black coffee (no creamer)
  • Tea (no milk)
  • Water
  • Apple juice (post-straining pulp)

These approved drinks help maintain energy levels without flaring organs that make digestion process lengthy and painful giving eventual results way less satisfactory compared to goals hoped-for earlier.


If you think about it..Everybody hates dietary restrictions… especially those enforced prior medical testing procedures such as “THE” Colonoscopy! Nevertheless following these prescribed guidelines promises efficient diagnosis post procedure so worth sticking with!

Therefore we suggest avoiding whole grains foods like oatmeal until after the test but instead swapping into soup broths /water and apple juice instead. This will ensure that you get accurate readings, and your doctor is able to give you the best possible advice based on a clear snapshot of what’s happening in there digestive tract!
