How does TCM know diabetes?

The understanding of diabetes in TCM is the earliest in the world, which was discussed in Huangdi Neijing during the Spring and Autumn Period and the Warring States Period. It is believed that diabetes is closely related to rich life and rich diet. Later generations continue to supplement and develop. For example, Chinese medicine books in Sui and Tang Dynasties pointed out that diabetes should pay attention to diet therapy and physical exercise. Dr. China first pointed out that urine of diabetic patients is sweet, and used it for the diagnosis of diseases. Chinese medicine has detailed records on the symptoms and complications of diabetes. According to its clinical symptoms, Chinese medicine believes that diabetes belongs to the disease of "quenching thirst" (note: Chinese medicine refers to diseases with particularly dry mouth, generally called dry mouth, excessive drinking water and excessive urination, including diabetes and diabetes insipidus. ), manifested as excessive drinking, overeating, polyuria, emaciation, or turbid urine and sweet urine.

The early pathological changes of diabetes are mainly yin deficiency and dry heat. If the disease is not treated in time and correctly in the early stage, yin will damage qi (note: according to the principle that yin and yang are fundamental to each other, the deficiency of either side of the body will inevitably lead to the deficiency of the other side. Yang impairs Yin, and Yin impairs Yang: When Yang deficiency reaches a certain level, because Yang deficiency cannot be transformed into yin fluid, Yin deficiency occurs at the same time, which is called "Yang impairs Yin". Similarly, when yin deficiency reaches a certain level, yang deficiency occurs at the same time due to yin deficiency, which is called "Yin impairs Yang"; Yang impairs Yin impairs Yang "or" Yin impairs Yang impairs Yang "eventually leads to" deficiency of both yin and yang ";deficiency of both yin and yang is a pathological state rather than a physiological state. ), dryness and heat damage yin and consume qi, and at the same time, due to the dysfunction of human viscera, phlegm and blood stasis are produced, which hinders the operation of qi and blood. Therefore, the pathological changes in the middle stage of diabetes are deficiency of both qi and yin, and phlegm and blood stasis block meridians (note: phlegm and blood stasis block meridians. )。 For example, the course of disease is prolonged, and yin damages yang, which leads to the pathological changes of yin and yang deficiency in the later stage of diabetes.
