What Is the Difference Between Hypokalemia and Hyperkalemia?
Hyperkalemia in the elderly refers to serum potassium> 5.5mmol / L. Total potassium does not necessarily increase with hyperkalemia, but intracellular and extracellular potassium distribution is abnormal. Unless the kidneys are diseased, kidney function does not decrease in the elderly; therefore, hypokalemia is rare.
