What factors can cause hyperkalemia by shifting potassium out of cells?
Hyperkalemia due to shift of potassium from the cells can occur in metabolic acidosis, exercise, insulin deficiency, β-adrenergic blockade, and α-adrenergic stimulation, as well as conditions like hyperglycemia that increase serum osmolality. Hyperglycemia, which pulls water from the cells, can lead to a solvent drag that also shifts potassium from cells.
