What is the medical term for excessive urination?

The medical term for excessive urination is "polyuria." This condition is characterized by the production of abnormally large volumes of urine, which can be indicative of various underlying health issues, such as diabetes mellitus, diabetes insipidus, or chronic kidney disease. Understanding this term is essential in medical contexts where urinary frequency and volume can provide important diagnostic clues.

Other options represent different conditions: polydipsia refers to excessive thirst, oliguria denotes a reduced urine output, and hematuria indicates the presence of blood in the urine. Each of these terms points to distinct aspects of renal or systemic health, but they do not describe excessive urination. Recognizing these terms is crucial in the medical field for accurate patient assessment and communication.
