What to Expect During Your First Colonoscopy: A Step-by-Step Guide

by | Nov 7, 2025 | Surgeon

A colonoscopy is an important procedure that helps detect and prevent serious conditions such as colorectal cancer, polyps, and other gastrointestinal issues. If you’ve been searching for a colonoscopy doctor near me or a gastroenterology clinic near me in Surprise, AZ, it’s essential to know what to expect during the procedure. Understanding the process can help reduce any anxieties and ensure you’re fully prepared for the screening.

At the Center For Colorectal Disease Of Arizona, colonoscopies are performed as a routine part of preventive healthcare, especially for individuals over the age of 50, or earlier if you have specific risk factors. By addressing these concerns early, you can help ensure that any issues are identified and treated promptly. Here’s a step-by-step guide to what happens before, during, and after your colonoscopy.

What Is a Colonoscopy?

A colonoscopy is a medical procedure that allows a doctor to view the inside of your colon and rectum using a long, flexible tube equipped with a camera. This tube, called a colonoscope, provides clear visuals of the colon lining and can help detect conditions like colorectal cancer, polyps, or other abnormalities.

Colonoscopy screenings are especially important because they can identify polyps or early signs of cancer, conditions that often do not show symptoms in their early stages. Detecting and removing polyps early can reduce the risk of colon cancer significantly.

Preparing for Your Colonoscopy

Proper preparation is key to a successful colonoscopy. The preparation process ensures that your colon is clear of any waste, so your doctor can get a good view of the colon during the procedure.

Fasting

The day before your colonoscopy, you will need to fast for about 12 hours. This means avoiding solid food and drinking only clear liquids. Clear liquids include water, broth, tea, and clear juices, but avoid drinks with pulp, like orange juice. Your doctor will provide specific instructions, but it’s important to follow them closely to ensure your colon is adequately prepared.

Laxatives and Bowel Prep

In addition to fasting, you will likely be instructed to take a bowel preparation solution, which is a prescribed laxative. This will cleanse your bowel, ensuring that there is no residue left in your colon that could obscure the doctor’s view. The prep typically involves drinking a large amount of liquid that induces frequent bathroom visits. While this part of the process can be uncomfortable, it’s an essential step in ensuring the procedure’s success.

Hydration

Hydration is important during the preparation phase. While fasting, your doctor will allow clear liquids to help prevent dehydration. Be sure to drink plenty of fluids to stay hydrated while adhering to the fasting and bowel prep instructions.

What Happens During the Procedure?

Once you arrive at the gastroenterology clinic near me in Surprise, AZ, the colonoscopy procedure will typically take place under light sedation. This ensures that you are relaxed and comfortable throughout the process. You will be given medication through an intravenous (IV) line that makes you feel drowsy, but you will remain awake during the procedure.

The Colonoscopy Procedure

Once the sedatives take effect, the doctor will insert the colonoscope through the rectum and gently advance it through the colon. The colonoscope is equipped with a light and a camera that allows the doctor to view the lining of your colon and rectum on a monitor.

The doctor will carefully examine the colon for any signs of polyps, inflammation, or other abnormalities. The procedure typically takes about 20 to 30 minutes. While it might sound uncomfortable, the sedation and the minimally invasive nature of the procedure make it well-tolerated by most patients.

At times, air may be introduced into the colon to help the doctor get a better view, which might cause mild bloating or cramping. These sensations are usually temporary and will subside shortly after the procedure.

Removing Polyps or Biopsy

If the doctor finds any polyps during the colonoscopy, they may be removed immediately. This is a common part of the procedure. Any tissue removed will be sent for further testing. Biopsies may also be performed if the doctor notices any abnormal areas in the colon.

After the Procedure: Recovery and Results

After the colonoscopy, you’ll be monitored as the sedative wears off. You will likely feel a bit groggy, so it’s important to have someone with you to drive you home. Most people can return to their regular activities the following day, but you should avoid making any important decisions until the effects of the sedation have fully worn off.

Post-Procedure Discomfort

It’s common to experience some mild bloating, gas, or cramping after the procedure. This is caused by the air that was introduced into the colon during the procedure and should resolve quickly. Once the sedation has worn off and you’re feeling more comfortable, you can resume eating, starting with light foods.

Results and Follow-Up

Depending on the findings, your doctor may discuss the results of the colonoscopy with you immediately after the procedure. If polyps or other abnormalities are found, they will be sent for further testing, and your doctor will advise you on the next steps based on the findings. If no abnormalities are found, your doctor will recommend when to schedule your next colonoscopy, typically in 10 years for individuals with no family history or risk factors.
