Colonoscopy
A colonoscopy examines the lining of the large bowel and terminal ileum when accessible. It is used to investigate symptoms, assess inflammation, screen for colorectal disease and identify or remove polyps.
Why might a colonoscopy be recommended?
Reasons can include rectal bleeding, altered bowel habits, unexplained iron-deficiency anaemia, chronic diarrhoea, inflammatory bowel disease assessment, colorectal cancer screening or surveillance, and follow-up of previous polyps.
What happens during the procedure?
A flexible colonoscope is passed through the rectum to inspect the colon. Biopsies may be taken and polyps can often be removed during the procedure. Sedation is commonly used.
Bowel preparation
A clean bowel is essential for a high-quality examination. You will receive specific dietary and bowel-cleansing instructions. Medication adjustments should be discussed with the practice, particularly anticoagulants, antiplatelet medicines and diabetes treatment.
