Body Constitution refers to an individual's physical makeup, including their body shape and size, as well as any unique features or characteristics. It can also refer to a person's overall health and vitality, taking into account factors such as their diet, exercise routine, and lifestyle choices that affect their energy levels and immune system. In traditional Chinese medicine (TCM), body constitution is an important aspect of diagnosis and treatment, with practitioners considering factors such as a patient's skin texture, tongue shape, and pulse quality to determine their unique balance of yin and yang energies.
