What is hyponatremia?

Hyponatremia (say "hy-poh-nay-TREE-mee-uh") means that you don't have enough sodium in your blood compared to water. Sodium is both an electrolyte and a mineral. It helps keep the right mix of fluids in your body. Severe hyponatremia can be harmful to the brain and nervous system.

What are the symptoms of hyponatremia?

Hyponatremia may cause nausea, vomiting, headaches, and muscle weakness or cramps. You may not feel hungry. It can cause mood changes and make it hard to think clearly. Severe lack of sodium may lead to seizures or a coma.

How is hyponatremia diagnosed?

To diagnose hyponatremia, your doctor will examine you and ask about your health. You will also have a blood test to check on the sodium levels in your blood.

How is hyponatremia treated?

Your doctor may treat the medical condition or change the medicine that is causing your low sodium levels. You may get medicine to raise these levels. You may be told to limit the amount of water you drink. You may also add more salt to your diet or drink electrolyte replacement drinks.

How can you care for hyponatremia?

  • If your doctor recommends it, drink fluids that have sodium. Sports drinks are a good choice. Or you can eat salty foods.
  • If your doctor recommends it, limit the amount of water you drink. And limit fluids that are mostly water. These include tea, coffee, and juice.
  • Take your medicines exactly as prescribed. Call your doctor if you have any problems with your medicine.
