First, geriatric diseases and characteristics of geriatric diseases are divided into three categories: 1, due to the aging of the body and diseases, such as senile dementia, senile osteoporosis, cervical and lumbar spondylosis, etc.. 2. Diseases related to the decline of disease resistance after aging, such as cardiovascular and cerebrovascular diseases, hyperlipidemia, cerebral atrophy, emphysema, and immune deficiency. 3, with the youth and middle-aged also easy to occur, but also has its own characteristics of the disease, such as senile pneumonia, chronic gastritis, diabetes and so on. In addition, the elderly due to the physiological function of the decline and changes in the body’s internal environment will often appear insomnia, dizziness, constipation and other symptoms. Elderly diseases have obvious characteristics: 1, the onset of insidious, atypical symptoms, the onset of the initial diagnosis of Western medicine is difficult, easy to misdiagnosis and delayed treatment. 2, the elderly often several diseases, complex conditions, the focus is not prominent, conventional Western medical treatment is contradictory, in addition to the dose of Western medicine and young people are not the same. 3, the elderly onset of heavy, fast development, slow recovery, and even sequelae. Sub-health and its consequences Sub-health is a state of low or dysfunctional physiological function between health and disease, a critical state, mainly functional problems, patients have a variety of uncomfortable symptoms, but the relevant modern instruments can not be checked. Because of the complexity and variety of its manifestations, modern medicine does not yet have a specific standardized diagnostic parameter, and therefore there is no way to start and it is neglected. Generally speaking, people in the state of sub-health, although there is no clear disease, but there is a decline in mental vitality and adaptability, if you do not have any obvious disease, but for a long time in one or more of the following states, pay attention to the sub-health has issued an alarm to you: insomnia, fatigue, lack of concentration, forgetfulness, nervousness, irritability, panic attacks, depression, lack of appetite, easy fatigue, palpitations, poor resistance, nervousness, irritability, panic attacks, poor resistance, and so on. Poor, nervous, irritable, frequent colds or mouth ulcers, constipation, diarrhea, poor digestion, loss of appetite, bloating, chest tightness, decreased sexual function, feeling very tired, and even have the feeling of wanting to die, etc. If this disorder can not be corrected in a timely manner, it is very easy to cause organic diseases. Such as: gastrointestinal diseases, hypertension, coronary heart disease, cancer. People in a state of sub-health, generally not life-threatening, but if you encounter a high degree of stimulation, such as staying up all night, tantrums and other state of stress, it is easy to sudden death, is the “death of overwork”. Third, the advantages of Chinese medicine in the treatment of geriatrics, chronic diseases and sub-health Chinese medicine emphasizes “holistic treatment”, “different diseases with the same treatment”, smart Chinese medicine practitioners are first of all a general practitioner, Chinese medicine hospitals are divided into specialties only to facilitate the management of the Chinese medicine practitioners. “Look and know, cut and know”, “check and treat the disease”, you can find the patient’s body yin and yang, qi and blood, internal organs and the imbalance of the state of Ying and Wei, and often can find many functional and organic diseases of the disease mechanism, the use of traditional Chinese and Western medicine to identify the evidence, identify the disease treatment, to prevent the occurrence and development of the disease. The treatment can prevent the occurrence and development of the disease by using Chinese and Western medicine to identify and treat the disease. The advantages of “treating the root cause of disease”, “holistic treatment” and “investigating and treating the future” are suitable for the treatment of geriatric diseases, chronic diseases, difficult and complicated diseases and sub-health and their needs.
