How is hypokalemia diagnosed?

ANSWER

A blood test can show if you have hypokalemia. Your doctor will ask about your health history and will want to know if you’ve had vomiting or diarrhea.

You may take a urine test to see if you’re losing potassium when you pee. And since low potassium can affect your blood pressure, your doctor will check that, too.

He also may want to do an electrocardiogram (EKG) if he thinks you may have arrhythmia. This is a more serious side effect and might change the way your doctor treats the problem.
