Do I need to fast before my gastroscopy or colonoscopy?

Yes. You will receive written fasting instructions before your procedure. These instructions are important to ensure your safety and to allow the procedure to be performed effectively.

What should I expect on the day of my procedure?

You will be admitted to an accredited private hospital. Sedation is administered by a specialist anaesthetist to ensure comfort. Most procedures take between 10 and 30 minutes, followed by recovery in a monitored area before discharge.

How will I feel after my procedure?

Minor bloating or drowsiness can occur after the procedure and usually resolves quickly. Dr Abu Shawish will discuss the findings with you on the day, and a comprehensive report will be sent to your referring doctor.
