What to Expect When You’re Expecting… to Get a Colonoscopy


A colonoscopy is a vital medical procedure that plays a crucial role in detecting colon cancer and other gastrointestinal issues. Despite its importance, many people feel apprehensive about the process.

Understanding what to expect can help ease these concerns and ensure a smoother experience. Here’s a comprehensive guide on what to expect when you’re expecting…to get a colonoscopy.

What is a Colonoscopy?

A colonoscopy is a medical procedure used to examine the inside of the colon and rectum. It involves inserting a long, flexible tube called a colonoscope through the rectum into the colon. The colonoscope is equipped with a camera and light at its tip, allowing doctors to visually inspect the lining of the colon.

Colonoscopies are crucial for detecting abnormalities such as polyps, tumors, inflammation, and other conditions early on, including colorectal cancer. This procedure is considered essential for both diagnostic purposes and preventive care, as it can also enable the removal of precancerous growths before they develop into cancer.

Before the Procedure: Preparation is Key

Consultation with Your Doctor

The first step is scheduling a consultation with your gastroenterologist. During this appointment, your doctor will explain the procedure, discuss your medical history, and address any concerns you may have. It’s important to inform your doctor about any medications you’re taking, as some may need to be adjusted or paused before the procedure.

The Prep Diet

In the days leading up to your colonoscopy, you’ll need to follow specific dietary restrictions to ensure your colon is clear. Typically, this involves:

  1. Low-Fiber Diet: A few days before the procedure, you’ll switch to a low-fiber diet, avoiding foods like whole grains, nuts, seeds, raw fruits, and vegetables.
  2. Clear Liquid Diet: The day before your colonoscopy, you’ll transition to a clear liquid diet. This includes broth, clear juices (without pulp), tea, coffee (without milk or cream), and gelatin.

Bowel Preparation

Arguably the most dreaded part of the process is the bowel preparation. This involves drinking a prescribed laxative solution that will induce diarrhea to clear out your colon. It’s essential to follow the instructions carefully to ensure a thorough cleanse. Staying near a bathroom is advisable, as the laxative will work quickly and effectively.

During the Procedure: What Happens in the Exam Room

Arrival and Check-In

On the day of your colonoscopy, you’ll check in at the hospital or outpatient clinic. Make sure to have a friend or family member with you, as you won’t be able to drive yourself home afterward.


To ensure your comfort, you’ll receive sedation through an IV. This will help you relax and may make you feel drowsy or even fall asleep during the procedure. Your vital signs will be closely monitored throughout.

The Colonoscopy Itself

The actual procedure usually lasts between 30 to 60 minutes. While you’re sedated, the doctor will insert a long, flexible tube called a colonoscope into your rectum. The colonoscope is equipped with a light and camera, allowing the doctor to examine the inside of your colon and rectum. If necessary, small tissue samples (biopsies) can be taken for further analysis, and any polyps found can often be removed during the procedure.

After the Procedure: Recovery and Results

Immediate Recovery

After the procedure, you’ll be taken to a recovery area where you’ll rest until the sedation wears off. You might feel some bloating or cramping due to the air introduced into your colon during the procedure, but this should pass relatively quickly.

Going Home

You’ll need someone to drive you home, as the sedation can impair your reflexes and judgement for the rest of the day. Plan to take it easy and rest for the remainder of the day. Drinking plenty of fluids and eating light meals can help you feel better faster.

Receiving Results

Your doctor will discuss the initial results with you once you’re fully awake. If biopsies were taken or polyps removed, it might take a few days to a week to receive the final results. Your doctor will explain the findings and discuss any necessary follow-up steps or treatments.

Potential Risks and Complications

While a colonoscopy is generally safe, it’s important to be aware of potential risks. These include bleeding (especially if polyps are removed), perforation of the colon, and adverse reactions to the sedation. Contact your doctor if you experience severe abdominal pain, fever, or persistent bleeding after the procedure.

Conclusion: The Importance of Colonoscopies

A colonoscopy is a vital tool in preventing and detecting colorectal cancer and other gastrointestinal conditions. By understanding what to expect before, during, and after the procedure, you can approach your colonoscopy with confidence and ease. Remember, the short-term discomfort and inconvenience are outweighed by the long-term benefits of maintaining your health.
