What does polyuria refer to?

Polyuria refers to the production of abnormally large amounts of urine, often defined as more than 3 liters per day in adults. This condition can be caused by various factors, including diabetes mellitus, diabetes insipidus, and certain diuretic medications, among others. It is significant in clinical practice as it can indicate underlying health issues that require further evaluation and management.

In contrast, other terms encompass different urinary conditions: a decrease in urine output is referred to as oliguria, narrowing of the urine pathway is known as urethral stricture or obstruction, and the inability to urinate is termed urinary retention. Understanding these distinctions is crucial for healthcare professionals in diagnosing and treating urinary disorders effectively.
