Frequently Asked Questions

How much does a colonoscopy cost in Bangkok vs the US?▼

A colonoscopy in Bangkok costs ฿7,000–฿15,000 (approximately US$190–$410). In the US without insurance: $1,500–$4,000. Even with insurance, US co-pays can be $500–$1,500.

Is sedation available for a colonoscopy in Bangkok?▼

Yes — all major Bangkok private hospitals offer sedation for colonoscopy. Conscious sedation (midazolam + fentanyl) is most common — you are relaxed and pain-free but may have some awareness. Propofol (deep sedation) is available at most JCI hospitals on request — you are fully asleep. The sedation cost is typically included in the colonoscopy price at Bangkok private hospitals.

How long does a colonoscopy take in Bangkok?▼

The colonoscopy procedure itself takes 20–60 minutes depending on bowel preparation quality and any polyps found. Recovery from sedation takes 1–2 hours. You will need to fast the day before and follow bowel preparation. Plan for a full-day commitment — arrive early, undergo prep review, the procedure, and recovery. A same-day appointment is usually possible with advance notice.

Can I combine a colonoscopy with my executive health check-up?▼

Yes — all Bangkok JCI hospitals offer colonoscopy as an add-on to health check-up packages. Adding a colonoscopy to your executive package typically adds ฿7,000–฿12,000 to the package price. Note: colonoscopy requires separate preparation the day before your health check-up, so you will need 2 days in Bangkok. Most hospitals will schedule your health check-up bloods and imaging on day 1, and the scope on day 2.
