This article provides a step-by-step guide, personal experiences, insights from a gastroenterologist, answers to common questions, and some humorous tips to help ease your anxiety about preparing for a colonoscopy.


A colonoscopy is a medical procedure that allows a doctor to examine the lining of your large intestine (colon) for any abnormalities or signs of disease. It is typically recommended for people over the age of 50, and in certain cases, for those younger with a family history of colon cancer or other related health conditions. The procedure is vital for early detection and prevention of colon cancer, which is why preparing for a colonoscopy is crucial. This article will provide a step-by-step guide on how to prep for a colonoscopy, as well as offer personal experiences, insights from a gastroenterologist, and answers to common questions to put your mind at ease.

Step-by-Step Guide

Dietary Changes

Following a specific diet a few days before your colonoscopy is necessary to clear your bowels and make sure your doctor can adequately examine your colon. Here’s what you should eat and avoid:

  1. Eat:
    • Broth or clear soups
    • Plain gelatin
    • Ice pops
    • Black coffee or tea
    • Water
    • Sports drinks like Gatorade or Powerade (without any coloring)
  2. Avoid:
    • Solid foods
    • Non-clear liquids
    • Dairy products
    • Fruits and vegetables
    • Nuts and seeds

Bowel Preparation

It’s crucial to follow your doctor’s instructions for bowel preparation carefully, as an inadequate prep can cause the procedure to be incomplete, requiring a repeat colonoscopy. Here are some methods for colon cleansing and tips for making it more tolerable:

  1. Colon Cleansing Methods:
    • Polyethylene Glycol (PEG) – A powder dissolved in water that causes diarrhea and helps to cleanse the colon.
    • Miralax – A powder similar to PEG that’s dissolved in clear liquids.
    • Suprep Bowel Prep Kit – A prescription medication packed in two bottles that are mixed with water, which triggers diarrhea.
  2. Recommended Products for Bowel Preparation:
    • In addition to the above, your doctor may prescribe other methods like laxatives or enemas to ensure your colon is wholly cleaned.
    • It’s essential to avoid red or purple drinks or foods during the preparation process, as they can look like blood to the doctor during the exam and trigger false results or concerns.
  3. Tips for Making Bowel Preparation More Tolerable:
    • Chill the solution before drinking to make it more palatable.
    • Drink plenty of clear liquids to stay hydrated.
    • Place some wet wipes and Vaseline around the toilet to avoid irritation from frequent bathroom use.
    • Divide the prep into smaller portions and consume it gradually to manage discomfort and bloating.

Doctor’s Perspective

Insights from a Gastroenterologist

According to Dr. Sarah Thayer, a gastroenterologist at Massachusetts General Hospital, “Preparation for a colonoscopy involves a lot of work on the patient’s part, so it’s essential to follow the instructions given by your doctor carefully.” She also suggests starting the prep process earlier in the day than instructed to make sure you have enough time for the entire process.

Tips for Patients

Here are some tips from Dr. Thayer to help you prepare:

  1. Preparing for the Procedure:
    • Arrange for someone to drive you to and from the procedure as you won’t be able to drive yourself home.
    • Wear comfortable clothing to the hospital or clinic.
    • Double-check your prep instructions and follow them as closely as you can.
    • If you are taking medications, ask your doctor which ones you can still take and which ones to avoid.
  2. What to Expect During the Procedure:
    • The procedure itself may last around one hour, depending on the findings or the need for biopsies.
    • Your doctor may give you sedation if you’re feeling uncomfortable.
    • A nurse will monitor your blood pressure and breathing during the procedure.
  3. Aftercare Instructions:
    • You will be observed for an hour or more after the procedure to make sure the sedation wears off.
    • Avoid eating for an hour or two after the procedure.
    • Stay hydrated and drink plenty of fluids.

Answer Common Questions

Pain Level During Colonoscopy

The majority of people do not experience pain during colonoscopy, thanks to the sedatives they receive. However, some people may feel mild cramping or discomfort during the exam.

Necessity of the Procedure

Colonoscopies are mandatory for cancer prevention, as they can spot potential problems long before they become more severe or advanced. Screening and early detection of colon cancer could be life-saving, as it is one of the most curable types of cancer if detected early.

Screening Recommendations

For most people, it is recommended to start getting screened for colon cancer around the age of 50. However, if you have a family history of colon cancer or other conditions like inflammatory bowel disease (IBD), your doctor may recommend earlier screenings.

Concerns About Complications

Although rare, complications such as bleeding, perforation (a tear in the colon wall), and infection can occur. However, having the procedure done by an experienced gastroenterologist in an approved hospital or clinic lowers the chances for complications.


Importance of Early Detection of Colon Cancer

Getting screened for colon cancer can detect it early on, which can help your doctor remove any polyps before they become malignant and spread to other organs. Early detection could save your life.

Risks of Not Getting Screened

Not getting screened for colon cancer can lead to missing early detection and delaying treatment, which can lead to cancer spreading beyond your colon. At worst, the outcome could result in death.

Success Stories of Early Detection

Many people have undergone successful colon cancer treatments after having their cancers caught early on. These stories show that early detection leads to successful treatment and increased chances of survival.

Humorous Take

Introduction of Humor to Alleviate Anxiety or Fear

While undergoing a colonoscopy, adding some humor could help ease your anxiety and nerves. Here are some lighthearted, humorous tips on how to prepare:

  1. Laugh in the face of adversity.
  2. Create a colonoscopy playlist of your favorite tunes.
  3. Tell yourself that the colonoscopy is basically a “spa day” for your insides.

Merging Humor with Useful Tips

“Prepare your bathroom with plush towels and scented candles. Make it fancy, make it luxurious, you’ll be spending some time there. Just make sure to double-check the toilet paper supply.”

Example Stories or Anecdotes

“My friend’s son once walked in on him during his bowel prep, and my friend quickly pretended he was making margaritas to avoid explaining what had become of him.”


Getting a colonoscopy may seem scary and overwhelming, but it’s a necessary step for maintaining good health. By following this step-by-step guide and the tips shared by a gastroenterologist and a person who has experienced the procedure, you will be well-prepared and informed.
