Discharge Instructions for Hypernatremia
You have been diagnosed with hypernatremia. This means you have too much sodium (salt) in your blood. It can be caused by eating too much salt. But it's more often due to fluid loss. Loss of too much fluid can occur if the kidneys excrete too much urine. Fluid loss can also be caused by extreme sweating. This can happen during hot weather or exercise. It can be caused by diarrhea or vomiting. It can also be caused if you don't drink enough water. If not treated right away, it can cause a seizure or a loss of consciousness. It can also lead to death.

-
Extreme thirst

Fatigue

Confusion
