건강검진 is a large part of Korean healthcare. Insured adults get a basic NHIS check every two years, and many add a private package with ultrasound, endoscopy, CT or MRI. Gangnam has several dedicated screening centers and internal medicine clinics that run morning check-ups for walk-in patients who booked ahead.

A package typically takes 3 to 5 hours on a single morning. You fast from the evening before, have blood and urine tests, body measurements, X-ray, ultrasound and gastroscopy, and see a doctor at the end for initial findings. The full written report usually follows in 1 to 3 weeks; some centers prepare English reports.

The national check-up for insured patients is free or low cost. Private packages are non-covered, and prices range widely depending on scans included. Visitors pay the package price and cannot use the national program.

What to expect

Book at least a few days ahead. Colonoscopy requires bowel prep the evening before and the same morning.
Fast from 9 pm the night before. Water is usually allowed until midnight.
Bring your passport and wear clothes that are easy to change. Gowns are provided.
Sedated endoscopy means you should not drive or sign important documents that day.
Payment is usually on the day of the exam. Ask whether English reports cost extra.

Tips for international patients

Choose a package by the tests in it, not by name. Compare whether ultrasound covers thyroid, abdomen and pelvis.
Ask whether results can be emailed abroad and in what language.
If a finding needs follow-up, ask for the images on a disc to take home.

Health Screening in Korea: questions

How long does a full health check take in Korea?

Most packages run 3 to 5 hours in the morning, longer if colonoscopy or MRI is added.

Can I get my report in English?

Many Gangnam centers that see foreign patients prepare English summaries. Ask before booking and check the turnaround time.

Is the free NHIS check-up available to me?

Only if you are enrolled in NHIS and it is your eligible year. Notices are sent by NHIS by mail or app.

Can I do gastroscopy and colonoscopy on the same day?

Yes, it is common under one sedation. You will need bowel prep starting the evening before.

How fast will I know if something is wrong?

The doctor gives initial findings on the day. The full report follows in 1 to 3 weeks, and biopsies take about a week.

What should I avoid before a check-up?

Skip alcohol for 2 to 3 days and seeds or fibrous foods for 3 days before colonoscopy.
