Preparing for a Colonoscopy

Hearing your doctor say you’ll need a colonoscopy might cause some anxiety, but it’s important to remember that this is a routine, safe, and essential procedure in many cases.

A colonoscopy is often necessary to diagnose gastrointestinal conditions such as colitis, detect colon cancer or polyps, or determine the cause of unexplained chronic symptoms like bleeding, diarrhea, or persistent abdominal pain. (1)(2)

This guide outlines the essential steps to prepare for a colonoscopy.

How to Prepare for a Colonoscopy?

Your doctor will provide detailed preparation instructions, including dietary restrictions and prescribed laxatives to clear the colon of waste that could obstruct the examination. 

Here’s a general overview of the preparation steps:

1. Low-Fiber Diet (3–4 Days Before)

Start a low-fiber diet 3-4 days before your appointment. This makes digestion easier and ensures food passes quickly through your system. (3)

• Foods You Can Eat:some text
  • White rice, pasta, and bread.
  • Peeled and well-cooked vegetables.
  • Fruits without skins or seeds.
  • Eggs and lean meats.
• Foods to Avoid:some text
  • Tough meats and fatty foods.
  • Whole grains, seeds, and nuts.

2. Stop Solid Foods (1 Day Before)

The day before the procedure, avoid all solid foods and stick to clear liquids only. (1)(3)

• Allowed Clear Liquids:some text
  • Water.
  • Clear broths without vegetables.
  • Sports drinks.
  • Light-colored juices like apple juice.
  • Gelatin (Jello).
• Liquids to Avoid:some text
  • Coffee or tea with creamers.
  • Red, blue, or purple juices.
  • Opaque liquids like milk or orange juice.
• Important: Ask your doctor when to stop drinking liquids entirely. This is often from midnight or 2–4 hours before the procedure, depending on the type of anesthesia or sedation being used.

3. Take the Prescribed Laxative

Your doctor will prescribe laxatives and provide specific instructions on when and how to take it. Typically: 

• Half the dose is taken the evening before the procedure.
• The remaining dose is taken about 6 hours before your appointment.

The laxative will cause strong and frequent diarrhea, accompanied by bloating, nausea, or cramping. Plan to stay in a comfortable location close to a bathroom. (3)

4. Arrive with a Companion

The colonoscopy itself takes 30 to 60 minutes, and you’ll spend an additional 2–3 hours at the hospital for preparation and post-procedure monitoring.

Before the procedure:

• You’ll change into hospital-provided clothing.
• An IV catheter will be placed in your arm for sedatives.

Since the sedatives can affect your ability to drive or manage daily tasks, arrange for a trusted friend or family member to accompany you and provide support. (4)

By following these steps, you’ll ensure a smooth and successful colonoscopy procedure. If you have any questions or concerns about the preparation, don’t hesitate to contact your healthcare provider for clarification.
