The idea of "preventing disease" originated from Huangdi Neijing, which has been attached great importance by doctors in past dynasties and even modern medicine. According to modern medical theory, people's health status can be divided into three types: first, health is not morbid; Second, the desire for disease is not morbid; Third, the disease has not spread. Therefore, "prevention of disease" is aimed at these three States, which has the functions of preserving health and preventing disease, treating it if you want, treating it if you are slow, and preventing transmission if you treat it early.

According to the theory of modern medicine, human health can be divided into three types: one is healthy but not morbid, that is, the human body is in a healthy state without any disease; Second, wanting to get sick is not morbid, that is, the stage of hiding pathological information in the body, or a minor illness or ailment has a few premonitory symptoms or signs, but it is not enough to diagnose a certain disease; Third, the disease has not spread, that is, an organ of the human body has obvious lesions. According to the law of disease transmission and the physiological and pathological relationship between organs, the pathogenic factors may spread to other organs, but the pathogenic factors are still confined to one organ and do not spread.

"Prevention of disease" has the following functions in view of the above three states. First, before illness, disease prevention first: it refers to prevention before illness, which is the highest goal of medicine, the principle of healthy and non-morbid treatment, and the highest realm that smart doctors should pursue; The second is to treat the disease as soon as you want, so as to prevent it from taking too long: it refers to taking measures before the disease has no obvious symptoms, treating the disease at the beginning, and avoiding the unbalanced state of the body from continuing to develop. This is the treatment principle of latent disease without pathological state; The third is to treat the disease early and prevent it from spreading: it means that the disease already exists and should be diagnosed and treated as soon as possible to prevent it from spreading from shallow to deep, or between zang-fu organs. This is the therapeutic principle that desire is not morbid and transmission is not morbid. In addition, there is post-conditioning to prevent its recurrence: it refers to the time when the healthy qi is still weak, evil spirits are lingering, the body is in an unstable state, and the body function has not fully recovered. At this time, the body is either in a healthy state, the latent disease is not morbid, or the disease is not morbid, so we should pay attention to conditioning to prevent the recurrence of the disease.

Personally, I think the main reason is that the hospital examination results are normal and I feel uncomfortable. I should find a Chinese medicine doctor to recuperate.
