Scanty Urination

How Chinese medicine differentiates scanty urination — reduced urine volume, distinct from Dark Urine and Cloudy Urine already covered, which are about colour and clarity rather than volume — the five patterns you'll actually meet in practice, and the points for each. Acupuncture only — no herbs.

This page is educational, for practitioners and students — it is not a diagnostic tool and does not replace a proper in-person assessment. A sudden drop in urine output, especially with swelling or breathlessness, needs prompt medical evaluation (kidney function must be checked) before assuming a simple pattern.
