Hyperkalemia is the medical term that describes a higher than normal level of potassium in your blood. Potassium is a chemical that is very important for the function of nerve and muscle cells, including the heart muscle. Your blood potassium level is usually between 3.6 and 5.2 millimoles per liter (mmol/L). A blood potassium level higher than 6.0 mmol/L can be dangerous and usually requires immediate treatment.

1. Symptoms of hyperkalemia


The symptoms that hyperkalemia causes depend on the level of potassium in your blood. You probably won't see any symptoms, but if the potassium level is high enough, it can cause a number of symptoms, including:
Fatigue, weakness Numbness Numbness Nausea and vomiting Shortness of breath Chest pain Irregular heartbeat In extreme cases, high potassium can cause paralysis or heart failure. If left untreated, high potassium levels can cause your heart to stop beating.
If you have extremely high potassium levels, you will need to be hospitalized until they return to normal.

2. Causes of hyperkalemia


Usually high blood potassium levels are not true hyperkalemia. Instead, it can be caused by blood cells breaking down during or shortly after the blood is drawn. The cells rupture, releasing potassium into the blood sample. This skews the amount of potassium in the blood sample, even though your potassium level is indeed normal. When this is suspected, a new blood sample will be taken for re-testing.
Causes of hyperkalemia are related to a number of diseases and the use of certain medications, including:
