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]}
