Causes of Decreased Potassium and Sodium. Low levels of sodium or potassium, referred to as hyponatremia and hypokalemia, respectively, may occur for a variety of reasons. Low potassium levels may occur because of a lack of potassium-rich foods, such as fruits and leafy green vegetables, in a personâs diet.
