<section begin="clinical biochemistry" />'''Hypernatraemia''' is a disorder of [[sodium]] homeostasis characterised by high levels of sodium (< 146 mmol/L). It's a rare condition, and much less common than [[hyponatraemia]], due to the body's defence against hypernatraemia being very robust. Hypernatraemia due to loss of water is called [[dehydration]]. | <section begin="clinical biochemistry" />'''Hypernatraemia''' is a disorder of [[sodium]] homeostasis characterised by high levels of sodium (< 146 mmol/L).
