失调 is a versatile noun describing a state where something has lost its proper balance, coordination, or normal functioning. It covers three main usage domains: in health/medicine (e.g., 内分泌失调 'endocrine disorder'), in social/economic systems (e.g., 供需失调 'supply-demand imbalance'), and in orthopedics (e.g., 关节失调 'joint dislocation'). The word is abstract and context-dependent; you can use it for bodily functions, relationships, or systemic issues without needing a verb—it functions as a noun, so you say '出现了失调' (a disorder has occurred).
