Dispersion-thirst

Also wasting-thirst (Obs.). Any disease characterized by increased fluid intake, and copious urine, and categorized as upper dispersion, center dispersion, and lower dispersion, depending on the burner most affected.

Biomedical correspondence: diabetes mellitus, diabetes insipidus, and hypoadrenocorticism.

For treatment see upper dispersion; center dispersion; lower dispersion.

Essential Secrets from the External Official Library (外台秘要 wài tái mì yào) (Táng Dynasty, CE 752) describes dispersion-thirst as follows, Dispersion-thirst... is caused by kidney vacuity, and, in episodes, is characterized by extremely sweet urine. It also says, When the lumbus and kidney are both affected by vacuity cold, upward steaming is impaired, and grain qì all descends to form urine in such a way as its sweet flavor does not change. This nosology, with its particular mention of sweet urine (= glycosuria), fits the description of diabetes mellitus spoken of in biomedicine. Note that, although dispersion-thirst is often equated with diabetes mellitus, it is in fact larger in scope.
