What is high potassium?

Potassium is an important nutrient that helps keep your muscles working properly and your heartbeat regular. In people with healthy kidneys, extra potassium is removed from the body. But if your kidneys aren’t working well, they might not be able to do what they’re supposed to—and the potassium levels in your blood can become higher than normal. That condition is called high potassium (or hyperkalemia), and it can lead to serious health issues.
