Metabolic acidosis with a normal anion gap (AG) occurs with:
A. Diabetic acidosisMetabolic acidosis with a normal anion gap (AG) results from either acid administration (HCl or NH/) or a loss of bicarbonate from gastrointestinal (GI) losses, such as diarrhea, fistulas (enteric, pancreatic, or biliary), ureterosigmoidostomy, or from renal loss. The bicarbonate loss is accompanied by a gain of chloride, thus the AG remains unchanged.
