Hypokalemia in Severe Diarrhea

Q: What are the two mechanisms causing hypokalemia in severe diarrhea?


Answer:  The objective of the above question is to describe a less known reason of hypokalemia in severe diarrhea. Besides the loss of potassium in the diarrheal fluid, hypovolemia-induced secondary hyperaldosteronism also contributes to hypokalemia by increasing colonic potassium secretion.
