An insatiable appetite or excessive hunger; a medical condition of constantly feeling unsatisfied after eating.
From Greek 'a-' (without) plus 'koros' (satiety or fullness), literally meaning the inability to feel satisfied or full.
Acoria can result from damage to the brain's hunger-regulating centers—people with this condition can eat enormous amounts and never feel full, making it dangerous and psychologically distressing, quite different from simple overeating.
