Hypernatremia, also spelled hypernatraemia, is a high concentration of sodium in the blood. [3] Early symptoms may include a strong feeling of thirst , weakness, nausea, and loss of appetite . [ 1 ]
[3] [27] Once the patient is stable, it is important to identify the underlying cause of hypernatremia as that may affect the treatment plan. [3] [27] The final step in treatment is to calculate the patients free water deficit, and to replace it at a steady rate using a combination of oral or IV fluids.
This keeps serum sodium concentration – a proxy for solute concentration – at normal levels, prevents hypernatremia and turns off the osmoreceptors. [7] Specifically, when the serum sodium rises above 142 mEq/L, ADH secretion is maximal (and thirst is stimulated as well); when it is below 135 mEq/L, there is no secretion. [ 8 ]
Death can result if medical intervention is not forthcoming. These symptoms are generally a consequence of hypernatremia – an abnormally high sodium level in the blood. (There are myriad causes of hypernatremia, which is frequently encountered in medical practice; salt poisoning is not a common cause). [citation needed]
Excess of body water may also be a result of a medical condition or improper treatment; see "hyponatremia" for some examples. Water is considered one of the least toxic chemical compounds, with an LD 50 exceeding 90,000 mg/kg (90 g/kg) body weight in rats; [ 3 ] drinking six liters in three hours has caused the death of a human.
In summary, hyperaldosteronism causes hypernatremia, hypokalemia, and metabolic alkalosis. [ 13 ] Finer notes on aldosterone include the fact that it stimulates sodium-potassium ATPase in muscle cells , increasing intracellular potassium and also increases sodium reabsorption all along the intestine and nephron , possibly due to widespread ...

Type A (essential hypernatremia syndrome) involves an increase of the level in which solvent molecules can pass through cell membranes (osmotic threshold) for vasopressin release and the activation of the feeling of thirst. This is the most characterized sub-type of adipsia, however there is no known cause for Type A adipsia.
