This is the pattern of the Greater Yin stage, the first Yin stage of the Six Stages theory.
At this stage what's mainly affected is the Spleen Channel, often called "Lower Tai Yin".
In terms of symptoms patients typically experience classic signs of Spleen Yang Deficiency with Cold. Symptoms include a feeling cold, a lack of appetite, diarrhea and fatigue.
Precursor patterns: Greater Yin stage can derive from Lesser Yang 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 in the Interior.
Diagnosing a pattern in Chinese Medicine is no easy feat and should be left to professional practitioners. In particular one has to know how to differentiate between different types of pulses and tongue coatings, shapes and colors as well as learn to read from a long list of seemingly unrelated symptoms.
