How to Prepare for a Colonoscopy: Your Easy Guide

female doctor speaking with a female patient

A colonoscopy is a medical procedure that allows doctors to examine the inside of your colon (large intestine) for any abnormalities, such as polyps or cancer. It is recommended for people over the age of 50, or earlier for those with a family history of colon cancer or other risk factors.

While the procedure itself is relatively painless, the preparation can be uncomfortable and inconvenient. Here’s your easy guide on how to prepare for a colonoscopy.

Consult with Your Doctor

Before scheduling a colonoscopy, it is important to consult with your doctor to discuss the risks or any other concerns. Your doctor will provide instructions on how to prepare for the procedure, including dietary restrictions and medication adjustments.

Dietary Restrictions

The day before the colonoscopy, you will need to follow a clear liquid diet. This includes water, clear broth, tea, coffee (without cream or milk), sports drinks, and clear juices (such as apple or white grape).

Avoid any liquids that are red, purple, or orange, as they can be confused with blood during the procedure. You should also avoid solid foods, dairy products, and alcohol.

Medication Adjustments

Certain medications can interfere with the colonoscopy procedure or increase the risk of complications. Your doctor may advise you to stop taking certain medications before the procedure, such as blood thinners, aspirin, and nonsteroidal anti-inflammatory drugs (NSAIDs).

It is important to follow your doctor’s instructions and not stop taking any medication without their approval.

Preparation Kit

Your doctor will provide a preparation kit, which typically includes a laxative solution and instructions on how to use it. The laxative solution will help cleanse your colon before the procedure, ensuring that the doctor can get a clear view of the inside of your colon.

Tips for Preparing for a Colonoscopy

Preparing for a colonoscopy can be uncomfortable and inconvenient, but there are several tips that can help make the process easier:

Stay Hydrated

It is important to stay hydrated during the preparation process, as the laxative solution can cause dehydration. Drink plenty of clear liquids, such as water, to stay hydrated.

Stay Close to a Bathroom

The laxative solution will cause frequent bowel movements, so it is important to stay close to a bathroom during the preparation process. You may want to consider staying home or close to a restroom while you complete the preparation process.

Follow the Instructions Carefully

It is important to follow the instructions provided by your doctor and the preparation kit carefully to ensure that the colonoscopy is successful. This includes taking the laxative solution at the recommended time and following the dietary restrictions.

Use Flavored Laxatives

Some people find the taste of the laxative solution unpleasant. To make it more palatable, you can try using flavored laxatives or mixing the solution with a clear drink, such as ginger ale.

Wear Comfortable Clothing

During the colonoscopy, you will be asked to change into a hospital gown. To make the process more comfortable, wear loose-fitting clothing that is easy to take off and put on.

Bring a Companion

You will need someone to drive you home after the procedure, as the sedative used during the procedure can impair your ability to drive. Consider bringing a companion with you to the appointment to provide support and assistance.

Plan for Rest and Recovery

After the colonoscopy, you may feel groggy or tired from the sedative. Plan to rest and take it easy for the remainder of the day. You may also experience some mild cramping or bloating, which should subside within a few hours.

Use Moist Wipes

The frequent bowel movements caused by the laxative solution can cause irritation and discomfort. To help soothe the area, use moist wipes instead of toilet paper.

Stay Calm

It is common to feel anxious or nervous before a colonoscopy. To help manage your anxiety, try relaxation techniques such as deep breathing or meditation.

Ask for Help

If you are having difficulty with the preparation process, don’t hesitate to ask for help from a family member or friend. They can provide support and assistance during the process.

Plan for Transportation

In addition to having someone drive you home after the colonoscopy, you may also need to arrange for transportation to and from the appointment. Consider using a ride-sharing service or public transportation if you do not have a companion available.

At Curasia Endoscopy Centre, we provide transportation for the day of your procedure to and fro with no additional costs.

Follow Up with Your Doctor

After the procedure, your doctor will provide you with the results and any necessary follow-up instructions. It is important to follow up with your doctor and schedule any necessary appointments or procedures to ensure that your colon health is maintained.

Clear Your Schedule

The day before the colonoscopy, you will need to be at home to complete the preparation process. Clear your schedule and avoid any strenuous activities that may interfere with the preparation process.

Stay Warm

The laxative solution can cause you to feel cold or chilled. To stay warm, wear warm clothing and use blankets or a heating pad.

Stay Positive

While preparing for a colonoscopy can be uncomfortable, it is important to stay positive and focus on the benefits of the procedure. A colonoscopy can detect colon cancer early, when it is most treatable.

Stay Informed

Before the colonoscopy, ask your doctor any questions you may have about the procedure, the preparation process, and any potential risks or complications. Being informed can help ease anxiety and ensure that you are prepared for the procedure.

Follow Post-Procedure Instructions

After the colonoscopy, your doctor will provide you with instructions on how to care for yourself at home. It is important to follow these instructions carefully to ensure a smooth recovery.

Plan for Recovery Time

You may need to take a day or two off from work or other activities to recover from the colonoscopy. Plan ahead and make arrangements for any necessary time off.

Don’t Skip the Procedure

While the preparation process for a colonoscopy can be uncomfortable, it is important not to skip the procedure. Colon cancer is a serious condition that can be prevented or treated if detected early.

Stay Positive

Finally, it is important to stay positive and optimistic about the colonoscopy. The procedure is a routine part of colon health maintenance, and it can provide peace of mind and early detection of any potential issues.


While preparing for a colonoscopy can be uncomfortable and inconvenient, it is an important procedure for detecting colon cancer and other abnormalities. By following the instructions provided by your doctor and the preparation kit, staying hydrated, wearing comfortable clothing, and planning for rest and recovery, you can make the process easier and ensure a successful colonoscopy. If you have any questions or concerns about the preparation process, be sure to consult with your doctor.
