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 ]
This is what causes the hypokalemia, hypertension, and hypernatremia associated with the syndrome. Patients often present with severe hypertension and end-organ changes associated with it like left ventricular hypertrophy, retinal, renal and neurological vascular changes along with growth retardation and failure to thrive.
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]
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]
Symptoms of hypernatremia may vary depending on type and how quickly the electrolyte disturbance developed. [27] Common symptoms are dehydration, nausea, vomiting, fatigue, weakness, increased thirst, and excess urination. Patients may be on medications that caused the imbalance such as diuretics or nonsteroidal anti-inflammatory drugs. [27]
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.
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 ...
