What Are the Treatments for Hypernatremia in Renal Failure?

Hypernatremia occurs when sodium in the blood is higher than normal. It interferes with renal function, which makes the kidneys expel excessive amounts of water. Treatment for hypernatremia is to restore the sodium and water balance.

Causes

• Causes include excessive loss of fluids caused by not drinking enough water, prolonged vomiting or diarrhea or excessive sweating. Another cause is a high intake of salt.

Significance

• According to Pennsylvania State University, normal blood sodium levels are 135 to 145 milliequivalent per liter (mEq/L). Levels higher than 145 mEq/L are defined as hypernatremia.

Diagnosis

• Hypernatremia is diagnosed by examination of a blood sample.

Treatment

• Treatment for hypernatremia in renal failure is replacing lost fluids. Mild cases require drinking electrolyte replacement fluids, according to Pennsylvania State. However, more severe hypernatremia requires intravenous (IV) fluids.

Prevention/Solution

• Prevent hypernatremia by drinking plenty of fluids when you’re sick, in hot whether or exercising intensely, according to Pennsylvania State University.
