A colonoscopy might sound a bit intimidating, but it’s one of the best tools doctors have to keep your colon healthy. Whether you’re turning 45 or have a family history of colon cancer, knowing why you may need this exam can ease anxiety and help you take charge of your health. In this post, we’ll cover everything—from “when should you get a colonoscopy” to “how long does a colonoscopy take”—in simple terms. We’ve also asked Dr. Bharat Pothuri, a renowned gastroenterologist in Houston, to share his expert tips.
A colonoscopy is a safe, outpatient procedure that lets a specialist look inside your large intestine (colon) and rectum. During the exam, a thin, flexible tube with a tiny camera (a colonoscope) is gently guided through the rectum. The camera sends video images to a screen, so your doctor can spot:
Dr. Bharat Pothuri says, “A colonoscopy is both a diagnostic and preventive tool. We find issues early—often before you even have symptoms.”
“Knowing when should you get a colonoscopy helps catch problems early,” explains Dr. Pothuri. Guidelines vary depending on your risk:

“Your colonoscopy schedule depends on your risk,” says Dr. Pothuri. Here’s a quick look:
| Risk Level | Screening Interval | Notes |
| Average risk | Every 10 years | If your first colonoscopy is normal. |
| History of polyps | Every 3–5 years | Based on the number & type of polyps. |
| Family history | Every 5 years or as directed | Closer follow-up if relatives under 60. |
| IBD (ulcerative colitis or Crohn’s) | Every 1–3 years | Depends on disease duration & extent. |
One common question is: how long does a colonoscopy take? In most cases:
“In total, people spend about half a day on this process,” notes Dr. Pothuri. “But the peace of mind lasts a lifetime.”
