'hyperaldosteronism' originates from the combination of 'hyper-' meaning 'excessive,' 'aldosterone,' a hormone produced by the adrenal glands, and the suffix '-ism' indicating a condition or disease.

'Hyperaldosteronism' was coined in the 20th century as medical understanding of hormonal disorders advanced.

Initially, it meant 'a condition of excessive aldosterone,' and this meaning has remained consistent in modern medical terminology.
