Can I Eat Sushi Before a Colonoscopy?

Worried you’ll have to say goodbye to your beloved sushi rolls before your upcoming colonoscopy? I’ve got good news for you. As a food blogger and colonoscopy veteran myself, I know firsthand that the pre-procedure diet doesn’t have to be as restrictive as you might think.

Now, I’m not saying you should go on a sushi-eating rampage the night before your colonoscopy. Your doctor’s instructions come first when it comes to what you should and shouldn’t eat. But the latest research shows that there are no specific restrictions against eating sushi before a routine colonoscopy.

In this article, we’ll go over the pre-colonoscopy diet facts. I’ll share tips from my own experiences for enjoying some of your favorite foods (yes, even sushi!) before the procedure. We’ll also discuss:

  • Why your doctor may recommend avoiding certain foods
  • When you may need to stop eating and drinking
  • Whether the clear liquid diet is totally necessary
  • How to eat smart in the days leading up to it

The key is being prepared and knowing what to expect. So read on to learn how you can relax and yes, even savor some yummy sushi, before your colonoscopy!

What Are the Colonoscopy Diet Restrictions?

First, let’s review the typical diet guidelines.

Your doctor will likely recommend:

  • Eating only low-fiber foods 3 days before
  • Switching to clear liquids 2 days before
  • No solid food intake the day before

This helps empty your colon prior to the colonoscopy. Your doctor needs a clear view to check for polyps or other abnormalities.

But notably missing from the list? A restriction on sushi specifically.

Are There Foods You Should Avoid Before a Colonoscopy?

Yes, your doctor may restrict high-fiber foods that could leave residue in your colon. So you may need to avoid:

  • Whole grains like brown rice, quinoa, oats
  • Fruits and vegetables with skins, seeds or membranes
  • Dried fruits and vegetables
  • Beans, lentils, nuts and seeds
  • Popcorn
  • Dairy products

So this rules out some sushi rolls with brown rice or avocado, for example.

But there’s nothing saying you must avoid sushi across the board. Keep reading to learn more.

Can I Eat Sushi the Day Before My Colonoscopy?

The day before your colonoscopy, you’ll likely be limited to clear liquids only. This allows your colon to fully empty.

So at this stage, you’ll need to avoid all solid foods, including sushi. Stick to:

  • Water, mineral water, soda
  • Clear juices like apple or white grape juice
  • Clear broths like chicken broth
  • Gelatin
  • Popsicles
  • Coffee or tea without milk, creamers or cream cheese

Drink plenty of liquids to stay hydrated. Then you’ll be ready for your colonoscopy the next day.

Is It Safe to Eat Sushi 2-3 Days Before Colonoscopy Prep?

In the 2-3 days prior to the all-clear liquid prep day, you can likely eat soft, low-fiber foods. This is where sushi may fit in.

According to research, there are no specific restrictions on eating sushi before a colonoscopy. It comes down to focusing on low-fiber options.

So in moderation, you can probably enjoy sushi rolls made with:

  • White rice rather than brown rice
  • Fish and shellfish like salmon or shrimp
  • Cucumber, mango, or avocado as toppings

Avoid sushi rolls with:

  • Brown or black rice
  • Tempura or fried ingredients
  • Membranes like seaweed wrapping
  • High-fiber veggies like carrots

Talk to your doctor, but a California roll or basic salmon sushi in moderation is likely fine 2-3 days prior. Just don’t overdo it!

Follow Your Doctor’s Orders for Your Colonoscopy Prep

While the research shows you can likely eat sushi in moderation up to 2-3 days before a colonoscopy, always follow your doctor’s orders first.

Every doctor may provide slightly different prep guidelines. So speak with your gastroenterologist about your sushi query.

There are also many factors that impact your personal prep needs:

  • Your age
  • Your medical history
  • Reason for the colonoscopy
  • If you’ve had polyps removed before

It’s essential to follow the customized plan from your doctor. This ensures your colon will be properly cleansed for the procedure.
