If you’ve been scheduled for a colonoscopy, chances are the prep is what’s making you nervous, not the procedure itself. And you’re not alone.

At Digestive Health Services (DHS), our GI specialists hear the same questions every day:
“Is the prep really that bad?”
“What can I eat?”
“What if I don’t finish it?”

Let’s clear things up. Below, our GI experts answer the most common colonoscopy prep questions, honestly, clearly, and without medical jargon.

Why Is Colonoscopy Prep So Important?

Colonoscopy prep cleans out your colon so your GI doctor can clearly see the lining of your digestive tract.

• A clean colon = accurate results.
• Poor prep can mean missed polyps, inconclusive findings, or even having to repeat the procedure.

Think of it like cleaning a window before looking through it; prep makes all the difference.

What Foods Can I Eat Before Colonoscopy Prep?

A few days before your procedure:

Stick to low-fiber foods, such as:

• White bread or toast
• Eggs
• Rice or pasta
• Lean chicken or fish
• Yogurt (without fruit pieces)

The day before:

You’ll switch to a clear liquid diet, including:

• Water
• Clear broth
• Apple juice or white grape juice
• Plain tea or black coffee (no cream)
• Clear sports drinks

Avoid red, blue, or purple liquids, as they can look like blood during the exam.

Is Colonoscopy Prep Painful?

Not painful, but it can be uncomfortable.

Most patients experience:

• Frequent bowel movements
• Cramping or bloating
• A feeling of urgency

Chill the prep solution, drink it through a straw, and take small breaks if needed.

What If I Can’t Finish the Prep?

This happens more often than you think.

If you’re feeling nauseous or struggling:

• Pause for 15–30 minutes.
• Take small sips instead of large gulps.
• Walk around to reduce bloating.

If you truly can’t finish, call DHS right away. Our team may adjust your prep or give additional instructions.

How Long Does Colonoscopy Prep Take to Work?

Prep usually starts working within 1–3 hours, but everyone’s body is different.

By the end, your stool should look:

• Clear
• Yellowish
• Watery

If it remains cloudy or solid, please contact your GI care team.

Can I Take My Regular Medications?

Some medications are suitable, while others may require adjustments.

Be sure to tell your GI doctor if you take:

• Blood thinners
• Diabetes medications
• Blood pressure meds
• Iron supplements

At Digestive Health Services, we provide personalized prep instructions based on your health history, so never guess.

Will I Be Awake During the Colonoscopy?

Most patients are comfortably sedated and don’t remember the procedure at all. The exam itself usually takes 20–30 minutes, and you’ll go home the same day with a driver.

What Happens If My Prep Isn’t Good Enough?

If your colon isn’t fully clean:

• Small polyps could be missed.
• The procedure may take longer.
• You might need to repeat the colonoscopy sooner.

That’s why following prep instructions closely is so important, and why DHS is always available to guide you through it.
