Prior to rehydration, rehydration, serum K usually remains normal, because: ① Hemoconcentration. Hemoconcentration ② During acidosis K moves from ICF into ECF. ③ Oliguria reduce the excretion of K. Along with rehydration serum K will gradually fall, because: ① Hemodilution. Hemodilution ②Acidosis Acidosis is being corrected, K returns from ECF to ICF. ③ K excretion is increased along with urine discharge. ④ Synthesis of glycogen with infused glucose needs K. ⑤Ongoing Ongoing loss of potassium due to diarrhea.
