Which term refers to an abnormally large amount of urine production?

Polyuria is the term that describes the condition of producing an abnormally large amount of urine. This can be indicative of various health issues, such as diabetes mellitus, diabetes insipidus, or certain kidney disorders. In normal circumstances, the kidneys filter out waste and regulate body fluids, but when there is an excess of urine production, it usually points to an underlying issue affecting these functions.

Dysuria refers to painful or difficult urination, which does not relate to the volume of urine produced. Oliguria signifies a reduced amount of urine output, often indicating a problem with kidney function or dehydration. Urinary retention is the inability to completely empty the bladder, which is the opposite of the condition characterized by polyuria. Thus, polyuria specifically captures the essence of excessive urine production, making it the correct term in this context.
