The most common cause of genuinely high potassium (hyperkalemia) is related to your kidneys, such as Acute kidney failure. Chronic kidney disease. Eat a diet high in potassium. Eating too much food that is high in potassium can also cause hyperkalemia, especially in people with advanced kidney disease. Foods such as melons, orange juice, and bananas are high in potassium. Take certain drugs that prevent the kidneys from losing enough potassium.
