Discharge Instructions for Hypernatremia

You have been diagnosed with hypernatremia. This means you have too much sodium (salt)  in the blood. It can be caused by a high salt intake. But it is more often due to fluid loss. Loss of too much fluid can occur if the kidneys excrete too much urine. This is called polyuria. Fluid loss can also be caused by excessive sweating. This can happen during hot weather or exercise. It can be caused by diarrhea or vomiting. It can also be caused if you do not drink enough water. If not treated right away, it is a seriouis problem that can cause a seizure or a loss of consciousness. It can also lead to death. 

Symptoms of hypernatremia include:

  • Extreme thirst

  • Fatigue

  • Confusion

  • Low blood pressure

Diet changes

Limit all foods that are high in sodium. Make sure to avoid:

  • Canned soups

  • Canned beans

  • Frozen dinners

  • Commercially prepared tomato sauce and spaghetti sauce

  • Pizza

  • Salted pretzels and crackers

Other home care

  • Drink more fluids as advised.

  • Have your sodium levels checked as often as advised by your healthcare provider. This is very important if you are taking a diuretic. This is a medicine that helps flush water from the body.

  • Replace your body fluids after vomiting or diarrhea. Ask your healthcare provider for the best way to do this.

  • Tell your doctor about all medicines you are taking. These include both prescribed and over-the-counter medicines. Some of these can raise sodium levels.

Make follow-up appointments as advised by our staff. Your healthcare provider will need to watch your condition closely. You may need extra care if you have a health condition that causes your hypernatremia.
