In TCM, what does a patient with Yang deficiency typically experience?

In Traditional Chinese Medicine (TCM), Yang deficiency is characterized by a lack of Yang energy, which is associated with warmth, activity, and metabolism within the body. A patient experiencing Yang deficiency often exhibits symptoms that reflect this deficiency, such as feeling fatigued and lethargic. This is because Yang energy is responsible for promoting circulation, digestion, and overall vitality. When Yang is weak, the body's energy levels drop, leading to a sense of tiredness and lack of motivation.

Symptoms associated with Yang deficiency may also include cold extremities, a pale complexion, and a preference for warmth, which further supports the idea of reduced energy and vitality. Unlike a state of excess Yang, which would lead to feelings of heat and agitation, a deficiency of Yang results in the opposite feelings of fatigue and a general low energy state.

The other symptoms presented in the choices relate more to either excess conditions, where there is heat or dryness, which would not align with the presentation of a Yang deficiency. These contrasting symptoms highlight the importance of understanding the underlying nature of the deficiency when assessing patient conditions in TCM.
