What is a common treatment for managing the symptoms of hypernatremia?

Managing hypernatremia typically involves correcting the high sodium concentration in the blood, and intravenous fluids, particularly those that are hypotonic, are a common treatment. Administering intravenous fluids helps to dilute the sodium in the bloodstream and restore a more balanced electrolyte level. This process aids in rehydrating the body's cells, which can become dehydrated due to the high sodium levels.

Intravenous fluids can be tailored to the individual’s needs, with options such as dextrose in water or normal saline being commonly used depending on the severity of the hypernatremia and any accompanying symptoms. This treatment aims to lower the sodium levels in a controlled manner to avoid potential complications associated with rapid changes in sodium concentration, such as cerebral edema.

In contrast, increasing sodium intake, consuming a high protein diet, or engaging in excessive exercise would worsen hypernatremia or not address the underlying issue of elevated sodium levels. Therefore, intravenous fluids stand out as the appropriate and effective treatment for managing symptoms associated with hypernatremia.
