(During DKA, serum glucose exceeds the threshold for reabsorption by the kidneys, resulting in glucosuria and an osmotic diuresis.
→ This diuresis is accompanied by a net renal loss of potassium with depletion of total body potassium stores.)
Treatment involves gradual fluid repletion and insulin administration. Insulin promotes potassium redistribution to the intracellular fluid compartment. Therefore, intravenous fluids are ★supplemented with potassium to prevent hypokalemia.
