Asthenia

/æsˈθiniə/ noun

Definition

A medical condition characterized by weakness, lack of energy, or loss of strength in the body.

Etymology

From Greek 'astheneia,' combining 'a-' (without) + 'sthenos' (strength), literally meaning 'without strength.'

Kelly Says

Asthenia appears in the medical records of athletes, soldiers, and chronic illness patients throughout history as doctors struggled to name the mysterious exhaustion that defied explanation before modern medicine understood autoimmune disorders and chronic fatigue.
