Colonoscopy with Endoscopic Evaluation and Biopsy (Colonoscopic Study)

What to Expect Before the Procedure

You’ll likely need to prepare by following a special diet and possibly taking laxatives to clear your bowels. Your doctor may also prescribe a clear liquid diet for a few days before the procedure. Avoid smoking and alcohol for 24 hours before the test. You may receive sedation to help you relax during the procedure.

During the Procedure

The procedure is done in a hospital or clinic setting. A nurse or technician will insert the colonoscope through your rectum and guide it through your colon. If needed, small tissue samples (biopsies) will be taken. The procedure usually takes 30 minutes to an hour. You may feel some discomfort, but the sedation helps keep you comfortable.

After the Procedure

After the procedure, you’ll rest for a short time before going home. You may experience mild cramping, bloating, or a slight fever. Avoid strenuous activity for the day. Follow your doctor’s instructions for any prescribed pain relievers or medications. You’ll need someone to drive you home since you’ll be sedated.

What the Procedure Can Detect

A colonoscopy can identify issues such as inflamed or damaged colon tissue, polyps (which can become cancerous over time), signs of inflammatory bowel disease (like Crohn’s disease or ulcerative colitis), and other abnormalities that may require further medical attention.
