The symptoms of hypernatremia are subtle and include [[weakness]] or [[lethargy]].
The symptoms of hypernatremia are subtle and include [[weakness]] or [[lethargy]].  With more severe elevations of the sodium level, [[seizure]]s and [[coma]] may occur.


===Symptoms===
==History==
Clinical manifestations of hypernatremia can be subtle, consisting of [[lethargy]], weakness, irritability, and [[edema]]. With more severe elevations of the sodium level, [[seizure]]s and [[coma]] may occur.
A detailed history is important for the diagnosis of the etiology of hypernatremia.


Severe symptoms are usually due to acute elevation of the plasma sodium concentration to above 158 mEq/L, which corresponds to an osmolar gradient of 30-35 mEq/kg between plasma and brain. Beyond that level, the rapid reduction of brain volume can cause rupture of cerebral veins leading to intracerebral and subarachnoid hemorrhage. Values above 180 mEq/L are associated with a high mortality rate, particularly in adults. However such high levels of sodium rarely occur without severe coexisting medical conditions.
Patients having hypernatremia may have a positive history of
* [[diabetes insipidus]]
* [[hyperaldosteronism]]
* [[Cushing's disease]]
* Neurological disorder such as dementia or impaired motor function
* Seizure disorder
* [[malabsorptive disease|Malabsorption]]
* Ingestion of excess sodium salts.  
Hypernatremic patients can also have a recent history of the following diseases:
* [[diarrhea]]


'''To note that if hypernatremia progresses over more than 24 hours, the brain adapts rapidly to plasma hyperosmolarity by the intracellular accumulation of many osmolytes such as amino acids (eg, glutamate)'''.
* [[burns]]
* [[exercise]] ([[increased sweating]])
* [[polyuria]]
* P[[polydypsia|olydypsia]] 


===History===
==== Drug history: ====
A detailed history is important for the diagnosis of the etiology of hypernatremia. It should mention any history of diabetes insipidus, hyperaldosteronism, Cushing's disease, neurologic disease, seizure disorder, malabsorptive disease and ingestion of excess sodium salts. Current diarrhea, burns, exercise (increased sweating), polyuria and polydypsia should be emphasized. Drug history should include diuretic use or ingestion of osmotic agents (eg, mannitol, lactulose).
Patients on the following drugs can also have high sodium levels:
* [[diuretic|Diuretics]]
* Lactulose
