polyhydramnios

This term is a specialized medical descriptor used primarily in obstetrics and gynecology. It carries a neutral, clinical tone and is used to describe a pathological state rather than a symptom. In a clinical setting, it is often contrasted with oligohydramnios, which refers to a deficiency of amniotic fluid.

As a medical condition denoting a specific physiological state, the word is uncountable. It does not take a plural form and is not used with indefinite articles like "a" in professional medical charting, although it may appear with "a case of" in general descriptive prose.
