Hypernatremia
Medically reviewed by Drugs.com. Last updated on May 4, 2025.
Hypernatremia is an imbalance of sodium and water in your body. The amount of sodium (salt) in your blood is higher than normal. Sodium is an electrolyte (mineral) that helps your muscles, heart, and digestive system work properly. It helps control blood pressure and fluid balance. Hypernatremia can become life-threatening if left untreated.
