What is a Colonoscopy?

A colonoscopy is a medical procedure that allows a doctor to examine the inside of your large intestine (colon) for abnormalities. Using a flexible tube with a tiny camera at the end, the doctor can check for colon polyps, inflammation, or signs of colon cancer. 

If necessary, tissue samples can be taken for further analysis. This procedure is essential for the early detection of serious conditions, allowing for timely treatment.

Why Would I Need a Colonoscopy?

Your doctor may request a colonoscopy for several reasons, including:

  • Screening for colorectal cancer – The American Cancer Society recommends routine colonoscopies starting at age 45 for most adults.
  • Investigating digestive symptoms – If you experience chronic diarrhea, rectal bleeding, or unexplained weight loss, this procedure helps identify potential causes.
  • Detecting and removing colon polyps – These growths can develop into cancer over time, making early detection crucial.
  • Family history of colorectal cancer – If a close relative has had colon cancer, you may need earlier or more frequent screenings.
 

By scheduling a colonoscopy, you take a proactive step in safeguarding your health. The team at Detroit Weight Loss Center can help determine if this screening is right for you.

How Do I Prep for My Colonoscopy?

Proper preparation is essential for an accurate and successful colonoscopy. The main goal is to completely clear the colon so the doctor has a clear view. Here’s what to expect:

  1. Dietary Changes – A few days before the procedure, you’ll need to switch to a low-fiber diet. The day before, you’ll be on a clear liquid diet only.
  2. Bowel Prep Solution – You’ll drink a prescribed laxative to fully cleanse the colon. This can be the most challenging part, but it’s necessary for a successful procedure.
  3. Medication Adjustments – Some medications may need to be paused or adjusted before your colonoscopy. Always discuss this with your doctor.
 

Although the prep can be inconvenient, it’s a crucial step for ensuring accurate results.

What Happens During the Procedure?

On the day of your colonoscopy:

  • You’ll be given pain medication and possibly sedation to keep you comfortable.
  • The doctor will insert a flexible tube into your rectum and slowly guide it through the large intestine.
  • Air or carbon dioxide is used to expand the colon for better visibility.
  • If colon polyps or other abnormalities are found, they can be removed or biopsied immediately.
 

The entire procedure typically takes about 30 to 60 minutes. Since sedation is used, you’ll need someone to drive you home afterward.

What Happens After the Procedure?

After your colonoscopy, you’ll spend some time in recovery while the sedation wears off. You may feel some bloating or mild cramping, but this is normal and should go away quickly.

Here’s what to expect post-procedure:

  • You can usually resume eating shortly after. Start with light meals.
  • It’s normal to pass gas as your body expels the air used during the procedure.
  • Your doctor will review any findings with you and discuss the next steps.
  • If tissue samples were taken, results may take a few days.
 

Most people can return to normal activities the next day, but it’s best to rest for the remainder of the day after the procedure.

What Are the Potential Risks or Complications of Colonoscopy?

While a colonoscopy is generally safe, there are a few potential risks, including:

  • Bleeding – If polyps are removed, minor bleeding can occur.
  • Perforation – In rare cases, the colon wall may be injured.
  • Reactions to Sedation – Some people may experience mild side effects from anesthesia.
 

Serious complications are uncommon, but it’s important to contact your doctor if you experience severe pain, excessive bleeding, or a fever.

For patients seeking alternative screening options, a virtual colonoscopy (a CT scan-based procedure) is available, though it may not detect smaller colon polyps as effectively.

Understanding the Results

After your colonoscopy, your doctor will discuss the findings:

  • Negative Result – No abnormalities were found, and you likely won’t need another colonoscopy for 10 years.
  • Positive Result – If polyps, abnormal tissue, or signs of cancer are found, additional testing or treatment will be recommended.
 

A positive result doesn’t always mean colon cancer, but it does mean further evaluation is needed. Your doctor will guide you through the next steps.
