Hyponatremia (say "hy-po-nuh-TREE-mee-uh") means that you don't have enough sodium in your blood. It can cause nausea, vomiting, and headaches. Or you may not feel hungry. In serious cases, it can cause seizures, a coma, or even death.
Hyponatremia is not a disease. It is a problem caused by something else, such as medicines or exercising for a long time in hot weather.
You can get hyponatremia if you lose a lot of fluids and then you drink a lot of water or other liquids that don't have much sodium. You can also get it if you have kidney, liver, heart, or other health problems.
Treatment is focused on getting your sodium levels back to normal.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
