Hyperkalemia is too much potassium in the blood. Potassium helps keep the right mix of fluids in your body. It also helps your nerves and muscles work as they should. And it keeps your heartbeat in a normal rhythm. Some things can raise potassium levels. These include some health problems, medicines, and kidney problems. (Normally, your kidneys remove extra potassium.)
Too much potassium can cause nausea. It also can cause a heartbeat that isn't normal. But you may not have any symptoms. Too much potassium can be dangerous. That's why it's important to treat it. If you are taking any of the medicines that can raise your levels, your doctor will ask you to stop. You may get medicines to lower your levels. And you may have to limit or not eat foods that have a lot of potassium.
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.
