‘瞧病’ literally combines ‘瞧’ (to look at, to visit — in this context, a colloquial verb meaning ‘to go see someone’) and ‘病’ (illness, sick person). Together, it means ‘to visit a sick person’, especially in informal spoken Mandarin. It emphasizes the act of going to see someone who is unwell — often to offer care, comfort, or support — rather than seeking medical treatment for oneself (which would be ‘看病’). The word carries warmth and interpersonal concern, commonly used among family, friends, or colleagues.

This expression is predominantly conversational and regional, especially common in Northern dialects including Beijing Mandarin. It’s rarely used in formal writing or medical contexts. Note that ‘瞧病’ does not mean ‘to examine a patient’ (that’s ‘诊病’ or ‘给病人看病’) — the subject is always the visitor, not the doctor, and the object is the ill person, not the illness itself.
