The prevalence of diabetes is increasing year by year, and it has become another chronic non-communicable disease that seriously endangers public health after cardiovascular diseases and tumors. The harm lies not only in the elevation of blood sugar itself, but also in a series of metabolic disorders and the resulting acute and chronic complications caused by the long-term increase of blood sugar. Most of the patients have a slow onset, and the clinical symptoms are mild or absent. Some of them visit the doctor with complications as the first symptom, and by the time the symptoms appear or are diagnosed, the course of the disease has often lasted for years to decades, and sometimes they may remain asymptomatic until they are found to have diabetes at the end of their lives, which makes early diagnosis, early treatment, and prevention of disease development difficult. In recent years, countries around the world have attached great importance to the implementation of diabetes prevention and early intervention, and proposed the prevention and treatment strategy of shifting the focus of treatment forward, which is fully consistent with the concept of “treating the disease before it occurs” in Chinese medicine, and this concept can be used throughout the entire process of diabetes management and treatment. The idea of “treating the untreated” in Chinese medicine has a long history, as early as in the “Yellow Emperor’s Classic of Internal Medicine”, which has been respected as the “father of medical schools”, it is written in the “Ling Shu – Inversion and Shun”: “The upper workers pierce the unborn. …… Therefore, it is said: “The upper worker treats the undiseased, not the already diseased”; “Su Wen – Four Qi Tuning Shen Da Lun” says: “Therefore, the sage does not treat the already diseased to treat the undiseased, and does not treat the already chaotic to treat the undisrupted, this is also said. If the disease has become and then the medicine, chaos has become and then the cure, like thirst and wear well, bucket and cast cone, is not also late”, which contains “prevent before the disease”, “has been sick to prevent change” two meanings, from both positive and negative aspects to emphasize “This has laid the foundation of the theory of “treating the untreated disease” and has become the motto of preventive medicine today. At the end of Han Dynasty, Zhang Zhongjing proposed in “The Essentials of the Golden Mean” that “when you see the disease of liver, you know that liver transmits spleen, so you should first strengthen the spleen”, which became a major rule to guide “treating the untreated disease”. In the Tang Dynasty, Sun Simiao emphasized that “the top doctor treats the disease that is not yet sick, the middle doctor treats the disease that wants to start, and the bottom doctor treats the disease that is already sick”, distinguishing the ability of doctors into three levels: top, middle and bottom. Zhu Danxi, one of the four schools of Jin Yuan, devoted his work “Danxi Xinfa” to “treating the undiseased without treating the already diseased”, in which “treating the undiseased” was elaborated as an important content. In the Qing Dynasty, Ye Tianshi put forward the preventive viewpoint of “first to protect the land from evil”, emphasizing the importance of taking active measures to prevent changes before they occur. After more than 2,000 years of continuous enrichment and improvement by successive generations of doctors, “treating the untreated” has gradually formed a theoretical system with profound connotations. According to the law of the onset of diabetes, the first thing to do is to “prevent the disease before it happens, and to maintain health”. “Health” is a state of balance between yin and yang in the body, and “disease” is not a state of complete absence of disease, but a state of imbalance. The hidden state of imbalance is called “not yet sick”, and the explicit state of imbalance is called “already sick”. The development from “health” to “disease” is a dynamic process of continuous change, and the seriousness of the disease causes obvious systemic or local symptoms called “onset”. In the diabetic high-risk groups, we carry out education on diabetes, guide scientific health care and exercise, and use diet, massage, qigong, channeling, martial arts and other health care means to regulate the balance of yin and yang in the body, dredge the meridians and channels, and regulate the mood and spirit, so as to keep the body “healthy”. As the “Danxi Xinfa” said: “Instead of saving and treating with the disease after, rather than regimen and no disease first, cover the disease into the medicine after, futile.” In pre-diabetes, when blood sugar has not yet reached the diagnostic standard, but insulin resistance or insulin secretion is already present, it is necessary to “save the disease and prevent the disease”. The Yellow Emperor’s Classic of Internal Medicine – Twenty-four – This Theory says: “The sprout is the disease of the undiseased, and the disease of the micro. Knowing first the three parts of the nine symptoms of regulation, that is, the treatment of its micro, so do not fail.” Therefore, we must intervene early, the first place to safe before the evil, save the system in the sprout stage, to combine the doctor and patient, so that “every family self-learning, everyone knows”, “where the doctor treats the disease …… must make the sick know it is important “The doctor should also be able to identify the presence or absence of yin and yang, and the growth or decline of yin and yang by observing the speech and color, examining the tongue and pressing the pulse, clearing the accumulated pathological products in the body, regulating the function of qi and blood in the internal organs, and making the blood and veins flow smoothly so that the body can reach a state of balance, thus preventing the “disease”. When diabetes has already occurred, it is important to “treat the disease early and prevent its transmission”. In the “Treatise on the Origin of Medicine”, it is said that “if the disease is shallow at the beginning, it is easy to treat, but if it is long and deep, it is difficult to treat.” There are already aura and minor illnesses exist, the disease is shallow, the condition is light, the damage to the righteousness is not yet serious, early detection and treatment, you can prevent the occurrence of the transmission between the internal organs, timely stop the spread of disease, deterioration. At this time, the imbalanced internal organs are treated, and according to the interdependence and mutual restraint between the internal organs, the spleen is tonified, the liver is drained, the phlegm is removed, the kidneys are benefited, the essence is filled, and the blood is invigorated, so that the progress of the disease is interrupted and the imbalanced internal organs are restored. Diabetes mellitus has been around for a long time, with both qi and yin injured, yin damage and yang, phlegm and stagnant blood paralyzing the arteries and channels, easily leading to a variety of pathologies in the internal organs, although “the disease becomes and then the medicine, it is just a futile effort”, although “long and deep, it is difficult to cure”, but benefit qi and nourish yin, eliminate phlegm and remove stagnant blood, clear heat and detoxify, warm But the method of benefiting qi and nourishing yin, removing phlegm and blood stasis, clearing heat and detoxifying, warming and tonifying kidney yang, etc., and according to the theory that long-standing illnesses enter the luo, long-standing illnesses and kidney, the place where the evil is not received first can also be intercepted and reversed to prevent the condition from going deeper. The thinking and connotation of “treating the disease before it happens” is the essence and core of preventive medicine in TCM, and also meets the requirements of modern medicine for diabetes management. The flexibility and personalized tendency of TCM’s diagnosis and treatment, as well as the relative safety of its treatment methods, give TCM an obvious and unique advantage in the management and treatment of diabetes, and the theory of “treating the untreated” in TCM is ahead of its time and responsive.
