Discharge Instructions for Hyponatremia (Pediatric)

Your child has been diagnosed with hyponatremia. This is a low level of sodium in the blood. Sodium helps the body work normally. Too little sodium can cause health problems. Very low sodium can cause death. A low level of sodium has many causes. In small babies it is commonly caused by formula that is watered down or by giving too much plain water to drink. In older children it can be caused by drinking excessive amounts of water, some medicines, dehydration, or severe burns. Illness of the kidneys, heart, and liver can also cause it. Below is what you need to know about home care.

Home care

  • Limit your child’s intake of fluids as advised.

  • Ask your healthcare provider for the best way to replace your child’s body fluids after vomiting or diarrhea.

  • Have your child replace fluids carefully after exercise or activities that cause sweating. Give your child a sports drink with electrolytes, or give another type of drink the doctor advises.

  • Tell your doctor about all medicines your child is taking. This includes both prescribed and over-the-counter medicine. Some of these can lower sodium levels.

  • Have your child take all medicines as directed.

  • Have your child’s sodium levels checked as often as advised. This is very important if your child takes a diuretic. This is a medicine that helps flush water from the body.
