Disease is the great enemy of human health, but disease is also our companion in life. A patient with a history of seeing 20 patients told me that three people in their unit who were in very good health and living in excellent conditions had passed away one after another from cancer not long ago. What does this mean? It shows that disease is actually a health alarm given by the body’s immune system. Some people are too sensitive to this alarm, and as a result, more and more diseases are seen under the alarm, while some people do not take this alarm seriously, and as a result, the diseases become more and more serious, and finally develop to the point of no cure. So we should have a scientific view of medical treatment of disease, that is, pay attention to the enemy, but do not have to be alarmed. Our human body is fighting with disease throughout its life, which is what the ancients said is the fight between the good and the evil, the righteousness of the internal, the evil can not dry, the evil of the fight, its gas will be weak. So what exactly are the diseases that threaten human health now? 1, acute infectious diseases, including bacteria, viruses, parasites, etc.; 2, bacterial inflammatory diseases such as skin, organ and tissue infections and viral; 3, diseases of the vascular and nervous system such as cerebrovascular disease, nerve damage, coronary heart disease, etc.; 4, diseases of the endocrine system such as diabetes, thyroid, hypertension, hyperlipidemia, etc.; 5, occupying tumor-like diseases, including benign and malignant; 6. 6. common diseases of the visceral respiratory, circulatory, digestive, urinary and reproductive systems; 7. diseases of motor tissues, including spine, bones, muscles, joints, soft tissues, etc.; 8. psycho-spiritual including various neurological disorders, sleep and emotional abnormalities and the so-called “difficult and complicated diseases”. 9, food safety, water and environmental pollution, accidental injuries, natural disasters, war, etc. It is worth pointing out that according to the modern scientific classification of diseases, common diseases can be clearly identified parts, the reason why there are many common diseases that are not clear, just because of the level of diagnosis and serious attitude of doctors, whether Chinese medicine or Western medicine, there are good doctors and irresponsible doctors. However, many major diseases have a process of occurrence and development, so clinical misdiagnosis and misdiagnosis are inevitable, which requires our patients to comply with medical advice and regular physical examination, so that doctors can prescribe the right medicine. We see many people after the onset of the disease will say: my body has never been sick, their own disease also insisted not to see, to not be able to adhere to the time but still do not believe in doctors, their own diagnosis of their own disease, their own medicine, do not know anyone, no matter how great the body, there will be the first attack, people are not surprisingly sick. In addition, diseases can happen to everyone, especially when you get older, the human body’s organs aging, all kinds of diseases can happen, and not only a disease occurs, can make a variety of diseases at the same time, so in the patient’s consultation, the doctor in symptomatic treatment, this disease just cure, that disease will also occur, even when hospitalized for stroke, but also can happen again, so patients Therefore, the patient must have a scientific attitude to seek medical treatment and go to the doctor according to the patient’s changing condition, not to be trapped in a well. In addition, our medicine is developing day by day. A disease that was not diagnosed yesterday does not mean that it cannot be cured today, because our modern medical diagnosis level and medical technology are advancing. We must be convinced that science can eventually overcome diseases. Of course, the key to the treatment of diseases is early detection, and the treatment and conquest of diseases depends on the progress of science and technology.
