With further development of the bio-psycho-social medical model, people began to re-examine the knowledge of disease and health. The concept of sub-health has also been proposed in western medicine. Because of the lack of a specific standard, it is difficult to make clinical diagnosis and treatments for sub-health. Chinese medicine constitution theory has been widely accepted in China, and has a set of executable standards. This paper puts forward a new research method that connects the sub-health in western medicine and Chinese medicine constitution theory together. The potential relationships and influences between Chinese medicine constitution theory and sub-health were analyzed and key content and research progress were discussed. The research method in this paper will provide new ideas for sub-health research.
