A colonoscope is a long, flexible medical scope used to look inside the colon and rectum. It has a light and camera at the tip that sends images to a monitor. Clinicians use it during a procedure called colonoscopy. Some colonoscopes also have channels for tools used to remove polyps or collect tissue samples.

The camera helps the clinician check for polyps, bleeding, inflammation, narrowing, or abnormal tissue. Tools can pass through the scope when a biopsy or polyp removal is needed.
A colonoscope can be used for colorectal cancer screening and to investigate symptoms. These symptoms can include blood in the stool, bowel habit changes, unexplained anemia, abdominal pain, or ongoing diarrhea. It can also help monitor inflammatory bowel disease or follow up after earlier polyps. The reason for the exam affects preparation and follow-up.
Before a colonoscopy, the colon must be cleaned so the lining can be seen clearly. Preparation can include a clear liquid diet, laxative solution, and medication instructions. Poor preparation can hide polyps or lead to a repeat exam. Follow the timing from your care team closely, especially for blood thinners, diabetes medicines, or other daily medicines.
Colonoscopy is commonly performed, but risks can include bleeding, perforation, reaction to sedation, or infection. Mild gas, cramping, or small amounts of blood can happen after certain procedures. You will need recovery time if sedation was used, and someone else should drive you home. Call the care team for severe pain, fever, heavy bleeding, dizziness, or worsening symptoms.

Bowel prep clears stool from the colon so the lining can be seen. If the colon is not clean enough, small polyps or abnormal areas can be missed.
If you receive sedation, you should not drive afterward. Arrange a ride home and follow the recovery instructions from your care team.
