causes of hyperkalemia
Advanced kidney disease is a common cause of hyperkalemia. 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 cantaloupe, honeydew melon, orange juice, and bananas are high in potassium.
In patients with diabetic nephropathy, hyperkalemia may be caused by the syndrome of hyporeninemic hypoaldosteronism. The presence of typical electrocardiographic changes or a rapid rise in serum potassium indicates that hyperkalemia is potentially life threatening.
Article Sections. Hyperkalemia is a potentially life-threatening metabolic problem caused by inability of the kidneys to excrete potassium, impairment of the mechanisms that move potassium from the circulation into the cells, or a combination of these factors.
