Why Have a Colonoscopy?
- It allows direct and clear examination of the intestinal tissue for ulcers, inflammation or tumours. This is currently the most useful and accurate diagnostic method.
- Tissue samples (biopsy) can be taken immediately for early diagnosis and treatment.
How Is a Painless Colonoscopy Performed?
General Procedure:
- A trained anaesthetist assesses your condition and you will sign a consent form.
- An intravenous line is placed and vital signs are monitored.
- Mild sedative and pain-relief medication is administered to keep you comfortable and relaxed.
- After the procedure, you rest for approximately 30–60 minutes until fully alert before resuming normal activities.
- Medical staff remain at your side throughout the entire process.
Am I Suitable for a Painless Colonoscopy?
- If you have high blood pressure, heart disease, diabetes, asthma or drug allergies, please inform your medical staff before the procedure.
- All examinations carry some risk. However, provided you do not have severe drug allergies or heart/lung abnormalities, the risk is very low.
- The anaesthetist will reassess your condition on the day of the procedure. If painless endoscopy is not suitable, you will be informed.
Important Precautions
- You may feel drowsy for approximately 30 minutes after the procedure. It is recommended that a family member accompanies you home.
- Avoid driving, alcohol consumption, or signing legal documents on the day of the procedure.
- Fasting for 8 hours before the procedure (including water). However, if you take regular medication, please bring it with you to the clinic or hospital.
