Gastroscopy in Seoul: A Guide for International Patients
What a Gastroscopy Screens For
Gastritis, ulcers, H. pylori evidence, and — most importantly — early stomach cancer at treatable stages. Korea screens by endoscopy as a matter of routine, which is central to its early-detection record.
Sedation Options for Foreign Patients
Most international patients choose light sedation: you sleep through the procedure and recover in 30–60 minutes. Non-sedated is faster to recover from but less comfortable — both options are yours.
Preparation the Night Before
Fast from midnight (water in small sips is generally fine until a few hours before — your written instructions specify). Arrive with a companion or plan light activity if sedated.
Common Questions
Does gastroscopy hurt?
Under sedation, no — most patients report no memory of the procedure at all.
How long is recovery after sedation?
30–60 minutes at the center; avoid driving and heavy meals for the rest of the day.
Can biopsy be taken during screening?
Yes — suspicious areas are biopsied on the spot, with results in your report.
How often should I repeat gastroscopy?
Korean guidelines commonly suggest every 1–2 years for adults over 40; your physician will advise per findings.
