What condition is characterized by an inadequate production of urine?

The condition characterized by inadequate production of urine is known as oliguria. This term specifically refers to the production of urine that is less than normal, typically defined as less than 400 milliliters per day in adults. Oliguria can be indicative of various underlying health issues, including dehydration, kidney dysfunction, or obstruction in the urinary tract.

In contrast, anuria refers to a complete absence of urine production, which is a more severe condition than oliguria. Polyuria describes the excessive production of urine, often associated with conditions like diabetes mellitus or diabetes insipidus. Dysuria involves difficulty or discomfort while urinating, which is not related to the volume of urine produced. Understanding these distinctions helps in diagnosing and managing urinary conditions effectively.
