Fasting & Preparation Before Your Seoul Checkup
Fasting Rules: What and When to Stop
No food after midnight (8–12 hours before screening); small sips of water are generally acceptable until a few hours prior — your written instructions give exact cutoffs, which control lab and ultrasound quality.
Bowel Prep for Colonoscopy
Low-residue eating the prior day, then the split-dose prep solution on schedule. Incomplete prep is the top cause of repeat procedures — follow the timing precisely.
Medications: What to Pause and What to Keep
Blood thinners, diabetes medication, and some supplements need advance discussion — tell the desk your medication list at booking and you'll get specific written guidance rather than guesswork.
Common Questions
Can I drink coffee the morning of?
No — coffee breaks the fast and can affect results; water per your instructions only.
What if I accidentally ate?
Tell staff at registration — some tests can proceed and others reschedule; honesty preserves result quality.
Do I take blood pressure pills that morning?
Commonly yes with a sip of water, but confirm your specific medications with the desk in advance.
How strict is the 'night before' alcohol rule?
Skip alcohol 24 hours or more before screening — it distorts liver values.
