The signs and symptoms are usually not clearly indicative of hypernatremia. Often the condition is missed in debilitated and hospitalized patients as other more likely causes of the presenting symptoms are first considered. Hypernatremia is a blood sodium level exceeding 145 mmol/L. Diagnostic inve...

In adults, causes of hypernatremia include hyperalimenation, dehydration secondary to either fever or elevated ambient temperature, NaHCO3 administration, and diabetes insipidus. The signs and symptoms of hypernatremia are variable, including seizures and depression of sensorium. Associated metabolic ...

If both hypothalamic and renal function are intact, the urine osmolality in the presence of hypernatraemia should be above 600mOsmol/kg, this is typically seen in extra-renal causes of hypernatraemia If the urinary osmolality is less than 600mOsmol/kg despite hypernatraemia, it may indicate an...
The presence of nonelectrolyte solutes in urine causes an osmotic diuresis. Such solutes can be of either endogenous origin (e.g., urea or glucose) or exogenous origin (e.g., mannitol or glycerol). The presence of these solutes in tubular fluid impairs both sodium and water reabsorption, ...
Management of hyponatremia In patients who require non-emergency treatment in the hospital setting: - In patients with chronic severe hyponatremia who have mild to moderate symptoms (eg, dizziness, forgetfulness, gait disturbance, nausea, vomiting, confusion, and lethargy), hypertonic saline (typically...
Therefore, hypernatremia causes water movement out of cells, while hyponatremia causes water movement into cells, resulting in cellular shrinkage and cellular swelling, respectively. Serious central nervous system symptoms may complicate both conditions. Since hypernatremia and hyponatremia are accompanied ...
Diagnostic Strategies: urinary sodium or urinary chloride level is useful: Patients with hypovolemic hyponatremia due to nonrenal causes, urinary sodium or chloride level (<20 mEq/L) Patients with hypovolemic hyponatremia due to renal causes , urine sodium and chloride levels above 20 mEq/L Pati...
