Pathology

This is one of the two patterns of the Lesser Yin stage, the second Yin stage of the Six Stages theory

The Lesser Yin stage is where the disharmony mainly affects the Kidney Channel.

The Kidneys are considered the root of Yin and Yang in the body. As such, this stage has two patterns, called "Cold transformation" and "Heat transformation" that describe respectively a Kidney Yang Deficiency (with Empty-Cold symptoms) and a Kidney Yin Deficiency (with Empty-Heat symptoms).

This being the "Cold transformation" patterns, the pathology of this pattern is essentially Kidney Yang Deficiency with Empty-Cold symptoms like a feeling of cold, frequent pale urination or diarrhea. 

Causes

Precursor patterns: Lesser Yin Cold Transformation can derive from Greater Yin stage

External pathogenic factor: The main cause of this pattern is when an external pathogen, typically Wind-Cold, has invaded the body and had progressed deep in the Interior. By this advanced stage of the six-stages theory, it's transformed into a Yin pattern.
