Physiological oliguria arises with dehydration, which can result from water deprivation, excessive perspiration, vomiting, or diarrhea. It may also accompany blood loss; extensive burns and traumas; a drop in arterial pressure, as in shock and collapse; or increased production of the hormones aldosterone or vasopressin. Oliguria is frequently a symptom of kidney disease, for example, nephritis.
