Overview
A sigmoidoscopy examines the lower portion of the colon and the rectum. It's a shorter, simpler procedure than a full colonoscopy and is useful when symptoms point specifically to the lower bowel. It requires less preparation and no sedation in many cases.
When it’s recommended
- Bright red blood in stools
- Pain in the lower abdomen or rectum
- Changes in bowel habits affecting the lower bowel
- Follow-up of known conditions in the lower colon
- Evaluation of haemorrhoids or anal fissures
What to expect
The procedure takes about 10–20 minutes and is often done without sedation. A short flexible scope examines the rectum and lower colon. Most patients tolerate it well.
Usually just an enema on the morning of the procedure to clear the lower bowel. No fasting required in most cases. We'll give you specific instructions when booking.
You can return to normal activities immediately. Some mild gas or cramping is normal for a short time after.
