Unintentional Weight Loss

How Chinese medicine differentiates unintentional weight loss, 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. Unexplained weight loss always needs medical evaluation to rule out a serious underlying cause before assuming it is a simple digestive pattern — this page is supportive, not a substitute for that workup.
