I recommend Yonsei Life Internal Medicine in Jamsil.

Hello. I initially visited this hospital because it was designated as a national health screening center. It turned out to be a popular hospital in the area. They have two internal medicine specialists and one pediatrician. An acquaintance of mine had a colonoscopy and discovered a polyp, which was safely removed. They also have a Life Health Screening Center, which is great because it allows you to manage various diseases in advance.
