Colonoscopy FAQ

What Is a Colonoscopy?

A colonoscopy is an endoscopic procedure that allows a clinician to examine the lining of the large intestine (colon) and rectum using a flexible camera. It is commonly used for colorectal cancer screening, evaluating symptoms, and removing polyps.

Why Might I Need a Colonoscopy?

Colonoscopy may be recommended for:

• Routine screening for colorectal cancer
• Blood in the stool or unexplained anemia
• Persistent abdominal pain, diarrhea, or constipation
• Follow-up of previous polyps or abnormal imaging

How Do I Prepare for a Colonoscopy?

Preparation is essential for accurate results and usually includes:

• A clear-liquid diet the day before the procedure
• Bowel preparation with a prescribed laxative solution
• Adjusting certain medications, especially blood thinners or diabetes drugs
• Arranging a ride home due to sedation

What Happens During the Procedure?

Colonoscopy is typically done with sedation and takes 30 to 60 minutes. The scope is gently advanced through the colon, and air or carbon dioxide is used to expand the intestine for better viewing. Polyps or tissue samples may be removed during the exam.

What Is Recovery Like After a Colonoscopy?

Most people go home the same day. Common short-term effects include mild cramping or bloating that resolves within a few hours. You can usually return to normal activities the next day, but follow any dietary or activity instructions provided.

What Are the Potential Risks?

While colonoscopy is generally safe, possible risks include:

• Bleeding, especially if polyps are removed
• Perforation (a tear in the colon wall)
• Reaction to sedation
• Infection (rare)

When Should I Contact a Clinician?

Seek medical attention if you have severe abdominal pain, heavy bleeding, fever, or dizziness after the procedure. These can be signs of a complication that needs prompt care.
