I recommend the 123 Internal Medicine Clinic in Duam-dong.

This is 123 Internal Medicine Clinic, located in Duam-dong, Buk-gu, Gwangju. With three specialists, this clinic is larger than I expected, and the doctors are very thorough. Because it's located near the market, many seniors visit, and the staff is incredibly friendly. I liked that they offer chronic gastritis management, endoscopies, and health checkups. The female specialist specializes in gastroenterology, so I think it's especially good for those with digestive issues.
