Colonoscopy is one of the most effective tools for detecting and preventing bowel cancer, identifying polyps, and diagnosing conditions affecting the colon. At BMI Clinics, our experienced clinicians perform colonoscopy procedures with a focus on accuracy, safety and patient comfort, ensuring thorough assessment and clear guidance at every stage.
What Is a Colonoscopy?
A colonoscopy is a procedure that uses a thin, flexible camera to examine the lining of the large intestine (colon). It allows clinicians to:
- Detect early signs of bowel cancer
- Identify and remove polyps before they become cancerous
- Investigate symptoms such as bleeding, anaemia, changes in bowel habits or abdominal pain
- Diagnose inflammatory conditions such as colitis or Crohn’s disease
Because bowel cancer is highly treatable when detected early, colonoscopy remains one of the most valuable preventive health tools.
Who Should Have a Colonoscopy?
Colonoscopy may be recommended for individuals who:
- Are aged 45 or older (particularly with risk factors)
- Have a personal or family history of bowel cancer or polyps
- Experience rectal bleeding, persistent changes in bowel habits or unexplained abdominal symptoms
- Have positive faecal occult blood test (FOBT) results
- Have iron deficiency anaemia without a clear cause
- Require surveillance following previous polyps or bowel surgery
Your clinician will help determine the right timing and frequency for your needs.
Benefits of Colonoscopy
- Early detection of bowel cancer, when treatment is most effective
- Immediate removal of polyps, reducing future cancer risk
- Accurate diagnosis of gastrointestinal symptoms
- Peace of mind through clear, informed results
- Safe and well-tolerated with sedation for comfort
How to Prepare for a Colonoscopy
Preparation is essential for a clear and accurate examination. This typically includes:
- A temporary change to a low-fibre or clear liquid diet
- Bowel-cleansing medications to empty the colon
- Adjusting certain medications if advised
- Clear written and verbal instructions from your BMI Clinics team
Our staff ensure you feel supported and well-prepared for every step.
During the Procedure
- You will receive sedation to ensure comfort.
- The procedure typically takes 20–40 minutes.
- The clinician carefully examines the colon and may remove polyps or take biopsies if required.
- Monitoring occurs throughout to ensure safety.
Most patients remember little of the procedure due to sedation.
Recovery & Aftercare
- You will rest in recovery until fully alert.
- A responsible adult must accompany you home.
- Mild bloating or cramping may occur but usually resolves quickly.
- Your clinician will discuss initial findings and arrange follow-up as needed.
Pathology results (if biopsies or polyps are taken) are reviewed promptly with clear explanations provided.
