Polyuria (/ˌpɒliˈjʊəriə/) is excessive or an abnormally large production or passage of urine (greater than 2.5 L[1] or 3 L[6] over 24 hours in adults). Increased production and passage of urine may also be termed as diuresis.[7][8] Polyuria often appears in conjunction with polydipsia (increased thirst), though it is possible to have one without the other, and the latter may be a cause or an effect. Primary polydipsia may lead to polyuria.[9] Polyuria is usually viewed as a symptom or sign of another disorder (not a disease by itself), but it can be classed as a disorder, at least when its underlying causes are not clear.[citation needed]
