<prompt> A normal-anion-gap metabolic acidosis occurs in patients withDiarrhoeaDiabetic ketoacidosisMethyl alcohol poisoningAcute renal failure  <response>: During diarrhea, there is a loss of water, sodium, bicarbonate, and potassium in the fecal fluid leading to dehydration.Contraction of the extracellular fluid causes hyperchloremia.Hence the decrease in HCO3- is compensated by the corresponding increase in Cl- causing normal AG Metabolic acidosis.
