Overview
A colonoscopy examines the entire large intestine using a flexible scope. It's the gold standard for diagnosing colon problems and the best tool we have for detecting colon cancer early — when it's most treatable. Small polyps can also be removed during the procedure itself.
When it’s recommended
- Persistent change in bowel habits
- Blood in stools
- Unexplained weight loss or abdominal pain
- Iron-deficiency anaemia of unclear cause
- Colon cancer screening (typically age 45+)
- Follow-up if you've had polyps before
What to expect
The procedure takes about 20–45 minutes. You'll receive sedation. The scope is gently advanced through the entire colon. If polyps are found, they're usually removed during the same procedure and sent for testing.
A clear colon is essential. You'll follow a specific bowel preparation the day before — clear liquids only, plus a prescribed laxative solution. We provide detailed written instructions when you book.
Rest for 30–60 minutes after the procedure. Some bloating or mild cramping is normal. You shouldn't drive for the rest of the day. Most patients return to normal eating and activities by the next day.
