'''Hypernatremia''' is a common electrolyte problem and is defined as a rise in serum sodium concentration to a value exceeding 145 mmol/L. It is strictly defined as a hyperosmolar condition caused by a decrease in total body water (TBW) relative to electrolyte content. Hypernatremia can be caused by various conditions and can lead to a wide range of symptoms from lethargy and irritability to seizures and coma. | '''Hypernatremia''' is a common electrolyte problem and is defined as a rise in serum sodium concentration to a value exceeding 145 mmol/L.

Hypernatremia is a common electrolyte problem and is defined as a rise in serum sodium concentration to a value exceeding 145 mmol/L. It is strictly defined as a hyperosmolar condition caused by a decrease in total body water (TBW) relative to electrolyte content. Hypernatremia can be caused by various conditions and can lead to a wide range of symptoms from lethargy and irritability to seizures and coma.
Causes[edit]
Hypernatremia can be caused by a variety of conditions, including:
- Dehydration
- Diabetes insipidus
- Hyperaldosteronism
- Cushing's syndrome
- Kidney disease
- Hypertonic saline
- Medications such as diuretics, steroids, and some antibiotics
Symptoms[edit]
Symptoms of hypernatremia can vary depending on the severity of the condition. They can include:
Diagnosis[edit]
Diagnosis of hypernatremia is typically made through a blood test that measures the level of sodium in the blood. Other tests may be done to determine the underlying cause of the condition.
Treatment[edit]
Treatment of hypernatremia typically involves treating the underlying cause of the condition, as well as measures to lower the sodium level in the blood. This can include:
- Intravenous fluids
- Medications to manage symptoms and treat underlying conditions
- Dietary changes to reduce sodium intake
