What is the typical electrolyte derrangement for diarrhea?

Back

Hypovolemia
Hypokalemia

Direct loss
K+ shifts from intracellular --> extracellular to compensate --> lost in urine
Excretion of K+ to retain bicarb

Hyponatremia

Direct loss
Intake of hypotonic fluids --> dilutional hyponatremia

Hypocalcemia (less common)

Vit D def --> malabsorption of Ca
Acidosis --> decrease binding of Ca to albumin --> transient drop in total Ca

Metabolic acidosis (2nd to hypocarbia/ hypocapnia)

Intestinal contents rich in bicarbonate --> loss of bicarbonate-rich fluids
