Hyperkalemia occurs when your body can't filter out extra potassium that it doesn't need. Extra potassium interferes with your nerve and muscle cells. This can lead to complications in your heart and other areas of your body. The symptoms of high potassium may be unnoticeable to you.

Where does hyperkalemia occur?

Hyperkalemia can happen if your kidneys do not work well. It is the job of the kidneys to balance the amount of potassium taken in with the amount lost in urine. Potassium is taken in through the foods you eat and the liquids you drink. It is filtered by the kidneys and lost through the urine.

What part of the body does potassium affect?

Potassium is an essential mineral and electrolyte involved in heart function, muscle contraction, and water balance. A high intake may help reduce high blood pressure, salt sensitivity, and the risk of stroke. Additionally, it may protect against osteoporosis and kidney stones.
