Hello, you must have a physical examination. In addition to plastic surgery related items, there will be blood routine, coagulation time, blood type, liver and kidney function, electrocardiogram, chest radiograph and so on. And you need to rule out the possibility of organic diseases such as cardiovascular, lung, liver and kidney. South Korea's plastic surgery is first-class, and the related examination before operation is to ensure better cosmetic effect. Compared with this, the domestic technology can't reach it, so I suggest you choose a regular professional plastic surgery hospital when you go to South Korea for plastic surgery.
