Foods high in potassium include bananas, spinach, carrots and oranges. Decreasing potassium intake can cause levels in the body to drop, but this is not a common reason for a decrease in potassium levels. Low potassium levels can occur when the body loses too much fluid due to illness. This fluid loss may occur because of excessive amounts of vomiting and diarrhea.
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.Many individuals have a diet high in sodium due to convenience foods, so the lack of sodium-rich foods is not typically a concern.eople with mildly low potassium levels may benefit from taking oral potassium supplements, and eating a diet high in potassium-rich foods may help keep the levels from dropping again. Severe deficiencies of potassium may require supplemental potassium via injections or intravenous fluids.
