Hyperkalemia or high potassium level occurs when the level of potassium in your body and blood is higher than normal.
Potassium is a nutrient that is critical to the normal function of nerve, heart and muscles cells. It plays an important role in controlling activity of smooth muscle and skeletal muscle, as well as the muscles of the heart. It is also important for normal transmission of electrical signals throughout the nervous system within the body.
Normal blood potassium level is 3.6 to 4.8 milliequivalents per liter (mEq/L). Having a blood potassium level higher than 6.0 mEq/L can be dangerous and requires immediate treatment. Extremely high levels of potassium in the blood (severe hyperkalemia) can lead to cardiac arrest and death.
