Other physical signs of metabolic acidosis are not specific and depend on the underlying cause. Some examples include xerosis, scratch marks on the skin, pallor, drowsiness, fetor, asterixis, and pericardial rub for renal failure, as well as reduced skin turgor, dry mucous membranes, and fruity smell for DKA.
