Podcast #290: The Biochemistry of DKA

Author: Dave Rosenberg, M.D.

Educational Pearls

  • DKA commonly causes hyperkalemia, leading to peaked T-waves on ECG. However, DKA causes hypokalemia at the same time.
  • In DKA, glucose cannot be taken into the cells. This signals the body to create and use acidic ketones for energy. This leads to acidosis. To compensate for increased acid, H ions are pumped into cells. To maintain electroneutrality, K is pumped out of the cell. At the kidney, K is lost in the urine.
  • Overall, while serum K is high in DKA, total body K is low. The derangement in K can lead to life-threatening arrhythmias.
  • Treatment for DKA can induce hypokalemia, as the K will shift back into the cells with insulin administration. Therefore, treatment for DKA needs to include K.
