Metabolic acidosis caused by a loss of bicarbonate can be caused by ammonium chloride inges-tion or severe diarrhea. As the body is losing the bicarbonate, the kidneys increase their reabsorp-tion of chloride ions which keeps the anion gap within normal limits. This type of metabolic aci-dosis is sometimes referred to as hyperchloremic acidosis.
