The diagnosis of polyuria involves a thorough medical history and physical examination. A healthcare provider may ask about the onset, duration, and severity of the increased urination. Key diagnostic tests include urinalysis to check for infections or glucose, and blood tests to assess kidney function and glucose levels.
If a gynecological condition is suspected to be the cause, further tests may be ordered. For instance, hormone levels might be evaluated to check for imbalances related to conditions like PCOS or menopause. In some cases, imaging studies such as an ultrasound may be performed to examine the reproductive organs.
