My doctor says I need to have a colonoscopy. What is it like?

It’s a procedure where a doctor uses an endoscope (a long, thin tube) to look at the inside of your colon. The doctor will insert the endoscope into your rectum and then slowly move it up through your colon. They will take pictures of the inside of your colon as they go. This helps them see any polyps or other abnormalities that may be present. After the exam, the doctor will remove the endoscope and send it to the lab for analysis.
