What is a colonoscopy?

A colonoscopy is an endoscopic examination of the large intestine (colon) and rectum. A flexible camera is passed through the bowel to allow direct visualisation of the entire lining. It is the gold standard for bowel cancer screening and the investigation of lower gastrointestinal symptoms.

During the procedure, any abnormal areas can be biopsied and polyps can be removed — potentially preventing bowel cancer from developing. The procedure is performed under sedation and is well tolerated.

Why you may need a colonoscopy

Bowel Cancer Screening

Recommended from age 45 (upon request) and automatically from age 50 for average-risk individuals. Detects and removes precancerous polyps before they develop into cancer.

Investigating Symptoms

Unexplained changes in bowel habits, rectal bleeding, unexplained weight loss, or persistent abdominal discomfort.

Family History

First-degree relative with bowel cancer or polyps. Earlier and more frequent screening may be recommended.

Surveillance

Follow-up after previous polyp removal or bowel cancer. Regular monitoring reduces the risk of recurrence.

Who should be screened?

Current Australian guidelines recommend bowel cancer screening from age 45 (upon request), with automatic invitations from age 50. The frequency depends on your risk profile:

Bowel Cancer Screening Program: The Australian Government provides free screening tests for bowel cancer. Visit cancer.org.au/bowelscreening for more information and to request a screening kit.

GESA Certification: Our endoscopist holds the GESA (Gastroenterological Endoscopy Society of Australia) certification — the highest standard for endoscopic practice in Australia, requiring advanced training and ongoing quality assurance.

What to expect

Colonoscopy is a day procedure. You'll be sedated for comfort, and the examination typically takes 20–40 minutes. You can go home the same day.

Preparation

A clear bowel is essential for a thorough examination. You'll receive detailed preparation instructions, including a low-fibre diet the day before and a bowel preparation solution to drink. Proper preparation is the most important factor in a successful colonoscopy.

The Procedure

Performed under sedation (twilight sleep). You'll be comfortable and relaxed throughout. The endoscopist examines the entire colon, removes any polyps found, and takes biopsies if needed. You won't feel any discomfort during the procedure.

Afterwards

Recovery

Rest for a few hours. You'll need an adult to drive you home. Most people feel fine the next day and can resume normal activities.

Results

Initial findings discussed with you before you leave. Detailed report and any biopsy results sent to your referring doctor within a week.

Follow-up

If polyps were found, we'll recommend the appropriate interval for your next colonoscopy based on the findings.

Quality Standards

We meet GESA quality benchmarks: cecal intubation rate >95%, adequate bowel preparation, and appropriate adenoma detection rates.
