How Much Does Gastric bypass Cost in Republic of Korea?

The cost of gastric bypass in South Korea typically ranges from $16,000 to $19,200. Prices can vary depending on the hospital, the surgeon’s experience, whether it’s a standard Roux-en-Y or a mini gastric bypass, and if you need extra hospital days. In the United States, the average cost is $28,500 (per ASMBS). This means gastric bypass in South Korea is about 38% less than in the U.S.

South Korean hospitals usually include pre-op evaluations, anesthesia, the surgery itself, 2–5 days of hospital stay, post-op medications, and follow-up visits. In the U.S., the quoted price often covers only the surgeon and facility, while anesthesia, hospital stay, and aftercare are billed separately. Always confirm exactly what’s covered before booking your procedure.
