“Sub-health” is a new medical concept, in society there are many people, physical weakness, pain, poor eating, sleep, blood pressure fluctuations, panic, like stealing, mood boredom, anxiety, temper tantrums, hot flashes and other uncomfortable symptoms, go to the hospital examination but no organic lesions, all normal, said he has a disease. There is not enough evidence, but say he is healthy, but there is this or that uncomfortable symptoms appear. In fact, this is the transitional stage between health and disease, which we often call “subhealth”. Since the “subhealth” state refers to some functional changes without organic lesions, and the symptoms are mainly complained of, and the performance can be various, without uniform fixity, it is also called “variable statement syndrome”. There is no uniform judgment standard for “subhealth”, and there are great differences between Chinese and Western medicine in understanding and defining the scope of “subhealth”. In Chinese medicine, it is actually a temporary imbalance. The causes of “sub-health” can be various, such as overwork, physical exhaustion, energy consumption, psychological confusion, doubts and natural aging of the human body, as well as the preliminaries of some chronic diseases. Sub-health” can occur at any age, but it is more common in brain workers, and it can also occur in adolescence, so the problem of adolescent “sub-health” is also worrying; in old age, due to the natural aging of the human body, various “sub-health” symptoms can occur. “Therefore, the problem of “subhealth” in the elderly is complex and varied, and the problem of “subhealth” in some special occupations is also often The problem of “subhealth” in the elderly is complex and varied, and some special occupations are often “subhealth” problems. The problem of “sub-health” in the elderly is complex and varied. “Sub-health” can be manifested in physical, psychological, social adaptation, moral and other aspects, especially some syndromes, such as fatigue syndrome, neurasthenia syndrome, menopause syndrome, etc., but also some are pre-disease state, some cause carriers, such as hepatitis B virus carriers, tuberculosis carriers, and clinical examination indicators in the high and low limit value There are also clinical indicators in the high and low limit, such as blood pressure, heart rate, blood lipids, blood viscosity, blood glucose, renal function (such as serum creatinine, serum urea nitrogen, creatinine clearance, uric acid, urinary enzymes and microalbumin), liver function (total protein, albumin, prealbumin, cholinesterase, prothrombin time, ghrelin, glutamic aminotransferase, glutamic oxalacetic aminotransferase, adenosine deaminase, cholinesterase, lactate dehydrogenase, total bilirubin, direct bilirubin, total bile acid, blood ammonia, alkaline phosphatase, glutamate transpeptidase, 5′-nucleotidase, methemoglobin, etc.), blood potassium, blood calcium, etc. In addition, high risk factor status, such as overweight, excessive stress, smoking, high blood pressure, blood glucose, lipids, etc. The plant nerve function of “sub-healthy” people is often in an unstable state, so if they suddenly encounter violent psychological and emotional fluctuations, it will cause violent disorders of the plant nerve function, resulting in cardiac arrhythmia and even sudden death, or long-term pressure, desperate work to achieve the goal of life, the long-term accumulation of such chronic fatigue will eventually This kind of chronic fatigue accumulates over a long period of time and will eventually lead to sudden and violent death. This is the serious consequence of not paying attention to “subhealth”. Since there is no organic lesion in “sub-health” for a while, there is no fixed and better drug treatment, therefore, psychological treatment and Chinese medicine treatment become the key to the prevention and treatment of “sub-health”. For those with mild symptoms, short duration of time and good constitution, psychological and therapeutic dietary therapy can be taken first, and “diet should be in order, living should be in order, no delusional work should be done, life should be in order and psychological balance should be maintained”. If the symptoms are more serious, longer, or poorer, we should use the method of “fine-tuning” in Chinese medicine to achieve balance, so Chinese medicine is an ideal method of prevention and treatment, and the damage to the human body is relatively small. Not everyone needs to take medication for “sub-health”, even if you use Chinese medicine, you do not necessarily need to take Chinese medicine for a long time, you can take different courses of treatment and prevention depending on the symptoms, and take as little or no medication as possible. “Sub-health” is the “prelude” to disease, and the prevention of “sub-health” means the prevention of disease. We hope to pay attention to the awareness of “sub-health”.
