'''Polyuria''' ({{IPAc-en|ˌ|p|ɒ|l|i|ˈ|jʊər|i|ə}}) is excessive or an abnormally large production or [[Frequent urination|passage]] of [[urine]] (greater than 2.5 L<ref name="ur">{{Cite web |date=27 December 2013 |title=Urination – excessive amount |url=https://www.nlm.nih.gov/medlineplus/ency/article/003146.htm |access-date=30 December 2014 |website=Medline Plus |publisher=United States National Library of Medicine}}</ref> or 3 L<ref name="merck">{{Cite web |date=November 2013 |title=Polyuria |url=http://www.merckmanuals.com/professional/genitourinary_disorders/symptoms_of_genitourinary_disorders/polyuria.html |access-date=30 December 2014 |website=Merck Manuals}}</ref> over 24 hours in adults). Increased production and passage of urine may also be termed as [[diuresis]].<ref>{{Cite web |date=30 October 2013 |title=Definition of Diuresis |url=http://www.medicinenet.com/script/main/art.asp?articlekey=21221 |access-date=30 December 2014 |website=MedTerms}}</ref><ref>{{Cite web |title=Diuresis |url=http://medical-dictionary.thefreedictionary.com/diuresis |access-date=30 December 2014 |website=The Free Dictionary}}</ref> 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.
