Overview

A colonoscopy is a medical procedure that allows doctors to examine the inside of the large intestine (colon and rectum) using a thin, flexible tube with a camera called a colonoscope. It is commonly performed to screen for colon cancer, investigate symptoms such as bleeding or abdominal pain, and remove polyps before they turn cancerous. Colonoscopy is considered the gold standard for colon cancer screening.

What is a colonoscopy, and why is it done?

A colonoscopy is performed to check for colon cancer, polyps, ulcers, inflammation, or other bowel conditions. It is recommended for routine screening starting at age 45 (earlier for high-risk individuals), or if a patient has symptoms like rectal bleeding, changes in bowel habits, or unexplained abdominal pain.

How is a colonoscopy performed?

During the procedure, the doctor inserts a colonoscope through the rectum and advances it through the colon. The camera transmits images to a monitor, allowing for close examination. Polyps or abnormal tissues can be removed during the procedure for biopsy.

How do I prepare for a colonoscopy?

Preparation involves cleaning out the colon so the doctor has a clear view. Patients are instructed to:

  • Follow a special liquid diet for 1–2 days before the test
  • Take a bowel prep solution (laxative) to empty the colon
  • Avoid certain foods or medications as advised by the doctor
Is a colonoscopy painful?

No. Most patients are given mild sedation or anesthesia, making the procedure comfortable and pain-free. Some may experience mild cramping or bloating afterward, which usually resolves quickly.

What are the risks of a colonoscopy?

Colonoscopy is very safe, but rare risks include bleeding (especially after polyp removal), perforation of the colon wall, or adverse reactions to sedation. The benefits of early cancer detection and prevention far outweigh these risks.

What is recovery like after a colonoscopy?

Patients are monitored for a short time after the procedure and usually go home the same day. Normal activities can typically be resumed within 24 hours, though driving should be avoided until sedation fully wears off.

How often should I get a colonoscopy?

For average-risk adults, colonoscopy is recommended every 10 years starting at age 45. Those with a family history of colon cancer, certain genetic conditions, or previous polyps may need more frequent screenings.
