(Created page with "'''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. == Grading of severity == {| class="wikitable" |+ !Sodium level !Severity |- |146 - 154 |Mild |- |155 - 165 |Moderate |- |> 165 |Severe |} == Classification =...") |

Mild hypernatraemia does not usually require hospitalisation, but moderate, severe, or symptomatic hypernatraemia requires hospitalisation. Sever hypernatraemia requires [[intensive care]]. For treatment of [[diabetes insipidus]], see the corresponding article. | Mild hypernatraemia does not usually require hospitalisation, but moderate, severe, or symptomatic hypernatraemia requires hospitalisation.
