Study Notes
Hypernatremia
- Hypernatremia is defined as a serum sodium level > 145 mmol/L.
- Normal range for serum sodium levels is between 135-145 mmol/L.
Classification of Hypernatremia
- Hypernatremia can be classified into three types based on a person's fluid status:
- Hypovolemic hypernatremia (low volume)
- Euvolemic hypernatremia (normal volume)
- Hypervolemic hypernatremia (high volume)
Causes of Hypernatremia
- Hypovolemic hypernatremia can be caused by diarrhea, diuretics, and vomiting.
- Euvolemic hypernatremia can be caused by diabetes insipidus, and excessive administration of intravenous normal saline or sodium bicarbonate.
- Hypervolemic hypernatremia can be caused by primary aldosteronism, Cushing's syndrome, and renal disease.
Symptoms of Hypernatremia
- Early symptoms of hypernatremia include thirst, fatigue, and muscle weakness.
- Severe symptoms of hypernatremia that typically occur when levels are above 160 mmol/L include seizures, coma, and death.
