Painless Colonoscopy Seoul — sedation colonoscopy by a specialist, in English.
Sedation colonoscopy at Apgujeong Hana Clinic, Apgujeong, Gangnam. Board-certified gastroenterologist Dr. Yang Jae-hoon — IV sedation, CO₂ insufflation and same-day polyp removal. English results and follow-up.
Why so many people avoid colonoscopy — and why they shouldn't.
Fear of pain, discomfort and embarrassment are the most common reasons people delay or avoid colonoscopy — one of the most important cancer prevention procedures available. This fear is based largely on outdated experiences of colonoscopy without adequate sedation. At Apgujeong Hana Clinic, colonoscopy under IV sedation is a completely different experience.
With IV sedation — also called monitored anaesthesia care or conscious sedation — you enter a deeply relaxed, sleep-like state within seconds of the sedative being administered. You will be completely unaware during the procedure, feel no pain or discomfort, and most patients have no memory of the colonoscopy at all when they wake up. The procedure is performed by Dr. Yang Jae-hoon, a board-certified gastroenterologist with endoscopy sub-specialist certification and thousands of colonoscopy procedures performed.
After the procedure, you wake in our comfortable recovery area, where results are explained to you in English by Dr. Yang before you leave. Any polyps found are removed during the same procedure — no second visit required. CO₂ gas used throughout dramatically reduces post-procedure bloating compared to clinics using standard air.
Standard colonoscopy vs sedation colonoscopy — what's different.
Understanding the difference between colonoscopy with and without sedation helps you make an informed choice. At Apgujeong Hana Clinic, IV sedation is available for all colonoscopy patients who want it — and is the choice of the vast majority of our patients.

Why CO₂ makes such a difference after colonoscopy.
The most common complaint after colonoscopy is not related to the procedure itself — it is the bloating, cramping and abdominal discomfort that follows, caused by residual gas left in the colon after the procedure.
Standard colonoscopy uses room air to inflate the colon for visibility. Air passes very slowly through the intestinal wall and can take hours to work its way out — causing significant discomfort in the hours after the procedure that many patients find worse than the procedure itself.
At Apgujeong Hana Clinic, we use CO₂ (carbon dioxide) gas instead of air. CO₂ is absorbed through the colon wall into the bloodstream and exhaled through the lungs within minutes — the same way the body handles CO₂ from normal metabolism. The result is dramatically less post-procedure bloating and a much more comfortable recovery.
