Key Highlights
- Understand what gastroscopy (upper GI) and colonoscopy (lower GI) are and why they may be included in China health checks
- Learn how preparation works: fasting for gastroscopy and bowel prep for colonoscopy
- Discover what the experience is like for foreigners: procedure length, sedation options, and language support
- Plan timing: preparation often starts the day before; the exam itself typically fits in a morning
- Know when GI endoscopy is optional—based on age, symptoms, and risk factors—rather than routine for everyone
Important Facts
- Both procedures are performed by gastroenterology teams in hospital endoscopy units
- International or VIP departments often provide English support for foreigners
- Colonoscopy requires bowel preparation the day before; plan at least one full day for the process
- Gastroscopy and colonoscopy are valuable when clinically indicated but not mandatory for every health check
