Answer

A person with diabetes mellitus who has hyporeninemic hypoaldosteronism associated with diabetic nephropathy is at high risk for hyperkalemia due to a diminished ability to shift potassium into the intracellular space (insulin deficiency) and impaired renal excretion (aldosterone deficiency). A third circumstance is acute kidney injury from rhabdomyolysis or tumor lysis syndrome, in which hyperkalemia results from impaired renal excretion in addition to the release of large amounts of potassium from intracellular to extracellular fluid compartments.
