What Causes Low Potassium?
Common medications that are associated with lowering potassium are diuretics or “water pills”. These are often prescribed for individuals with hypertension to reduce body fluids and lower the strain on the heart. Diuretics may be given alone or in combination with other hypertensive medications. Diuretics cause increased amounts of potassium to be excreted in the urine, which increases the risk for low potassium. If you are taking a diuretic or taking a combination blood pressure medication that contains a diuretic, your physician may suggest a potassium supplement to replace the lost potassium.
