Hyponatremia occurs when the amount of sodium (salt) in your blood is lower 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.


Follow up with your healthcare provider as directed:

You may need to return for more tests. Write down your questions so you remember to ask them during your visits.


You may need to increase your intake of sodium. Foods that are high in sodium include milk, packaged snacks such as pretzels, or processed meats (bacon, sausage, and ham). Ask your dietitian to help you create a meal plan that is right for you.


Follow your healthcare provider's advice if you need to limit the amount of liquid you drink. Ask how much liquid to drink each day and which liquids are best for you. You may be asked to drink liquids that have water, sugar, and salt, such as juices, milk, or sports drinks. These liquids help your body hold in fluid and prevent dehydration.

Contact your healthcare provider if:

  • You have muscle cramps or twitching.
  • You feel very weak or tired.
  • You have nausea or are vomiting.
  • You have questions or concerns about your condition or care.

Seek care immediately or call 911 if:

  • You have a seizure.
  • You have an irregular heartbeat.
  • You have trouble breathing.
  • You cannot move your arms and legs.
  • You are confused or cannot think clearly.
