Fasting & Preparation Before Your Busan 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.
Prep Questions the IFC Desk Handles Daily
Blood thinners before endoscopy, diabetes medication timing on a fasting morning, supplements that skew liver values — send your medication list through the KakaoTalk channel when you book and the written answer comes back in your language, specific to your tier. Guessing is the only wrong approach.
Common Questions
When does fasting start?
Midnight before your screening — small sips of water per your written instructions only.
I take daily medication — what do I do?
Send the list through your booking channel; you'll get written, medication-specific guidance rather than a generic rule.
How disruptive is bowel prep?
One evening of split-dose solution and a low-residue day before — precise timing is in your instructions, and following it exactly avoids a repeat procedure.
What about alcohol?
Skip it for at least 24 hours before — it distorts liver values enough to matter.
