It seems that as soon as patients have kidney-related diseases, they immediately associate themselves with kidney deficiency, kidney deficiency, etc. and need tonic treatment. So are Western patients with kidney disease necessarily TCM patients with kidney deficiency evidence? The answer is no! Kidney deficiency is a type of TCM evidence generalized, basically can be divided into kidney Qi deficiency, kidney Yang deficiency, kidney Yin deficiency, Qi and Yin deficiency, Yin and Yang deficiency so several basic subtypes. In Western medicine, renal pathology refers to the pathological changes in the anatomy and physiological function of the kidney due to its own or external pathological causes, which leads to the physiological malfunction of the kidney. It can be seen that there is a big difference between the two. In simple terms, the scope of kidney deficiency in TCM is relatively broad, as TCM summarizes the physiological functions of the kidneys as “the kidneys are responsible for water, the kidneys collect essence, the kidneys collect qi, and the kidneys are responsible for reproduction”, and “the kidneys are open to the ears”. Therefore, anything related to the malfunction of water and fluid distribution in the body, the inability to collect essence, the inability to collect qi in the lungs, the disorder of reproductive function, and tinnitus and deafness are all related to the “kidney” in Chinese medicine. Therefore, in clinical practice, those who have kidney deficiency are not necessarily suffering from kidney disease in western medicine; and the kidney disease in western medicine may not have the manifestation of kidney deficiency in Chinese medicine at the beginning, but may be manifested as spleen deficiency, qi stagnation and blood stasis, deficiency of middle energy, etc. However, at the end of the disease, they often have more or less kidney deficiency. Therefore, if you have doubts about whether you have kidney deficiency or whether you have kidney disease, you should ask a professional doctor to help you to determine your condition through the four diagnoses of “look, smell, ask and cut”. Now the network information is developed, we can understand the encyclopedic knowledge with Baidu, which is a new way of science, is good. However, due to the professional and complicated medical knowledge, there are also individual differences and uncertainties, and patients in general do not have professional knowledge of biomedicine and lack the ability to comprehensively analyze and judge their conditions. The physiological and psychological burdens brought about by this are harmful and unhelpful, so when you are not feeling well, you need to consult a professional doctor, not to guess randomly and increase the burden on your mind; or to treat yourself according to the network guidance, although it is easy and simple to save the pain of queuing up at the hospital, but it is also very likely to lead to improper treatment and delay the disease, which is not desirable.
