What is sub-health

Hello, my friend. Sub-health is also called sub-health, the common symptoms such as the third state, intermediate state, wandering state, gray state and latent disease state, such as memory loss, inattention, slow thinking, slow response, bad mood, lack of self-confidence and lack of security. The epidemiological study of sub-health in China is mostly limited to cross-sectional survey, and the tools used are mostly self-rating scale or questionnaire. These surveys involve teachers, civil servants, enterprise personnel, community residents, medical staff and other different groups. Due to different definitions of sub-health and different questionnaires or scales, the detection rate of sub-health reported in various studies is also quite different, mostly between 20% and 80%. The detection rate of sub-health varies with gender, age and occupation, which has nothing to do with birthplace and nationality. Generally, the detection rate of women is higher than that of men, and the age group of 40-50 is higher than other age groups, especially teachers and civil servants. The main reasons leading to sub-health are: unreasonable diet, lack of exercise, irregular work and rest, lack of sleep, mental stress, great psychological pressure, long-term bad mood and so on. The main clinical features of sub-health include: ① symptoms reflected by feeling unwell, such as fatigue, weakness and emotional changes. , and its situation is difficult to clear for quite some time; (2) various weak manifestations caused by the decline of organizational structure or physiological function that is not suitable for age; ③ Microecological imbalance; ④ Pre-disease physiological and pathological changes of some diseases. Clinical manifestations are varied, such as fatigue, muscle joint pain, dizziness and headache, palpitation and chest tightness, sleep disorder, loss of appetite, epigastric discomfort, constipation in loose stool, sexual dysfunction, fear of cold and heat, easy to catch a cold, dry eyes and so on. Psychologically, it can be manifested as depression, distraction, impatience, irritability, fear and timidity, memory loss, inattention, listlessness and unresponsiveness. Social communication can be manifested in the following aspects: unable to assume the corresponding social role, difficult to work and study, unable to correctly handle interpersonal and family relationships, and difficult to conduct normal social communication. According to the clinical manifestations of sub-health state, it can be divided into the following categories: ① Physical symptoms such as fatigue, sleep disorder or pain are the main manifestations; ② Mental and psychological symptoms such as depression, anxiety, impatience, fear and timidity, or short-term memory loss and inattention are the main manifestations; ③ The decline in the frequency of interpersonal communication, or the decline in social adaptability such as interpersonal tension are the main manifestations. If any one of the above three items continues to attack for more than 3 months, and the diseases that may lead to the above performance are ruled out by systematic examination, they can be judged as sub-health in physical, psychological and social communication respectively. Clinically, the above three sub-health manifestations often coexist. Differential diagnosis Some foreign scholars think that sub-health and chronic fatigue syndrome are the same thing, and they are both studies of a group of physiological and psychological symptoms characterized by chronic fatigue, but some scholars hold different opinions. The United States is the first country to study chronic fatigue syndrome (CFS). From 65438 to 0998, the Centers for Disease Control and Prevention (CDC) officially named "Chronic Fatigue Syndrome" and defined it. 65438-0994 The international research group on chronic fatigue syndrome (led by the United States and composed of researchers from Australia, Britain and other countries) revised the diagnostic criteria of chronic fatigue syndrome. Definition of chronic fatigue syndrome: clinical evaluation, unexplained, persistent or recurrent chronic fatigue for 6 months or more. Fatigue is new or has a clear beginning (not lifelong); Not the result of continuous efforts; Can not be significantly relieved after rest; As a result, the ability to work, study, socialize or engage in personal activities is obviously lower than before. Diagnostic criteria: (1) chronic fatigue with unknown cause, persistent or recurrent, new onset or definite onset time, non-congenital, not obvious after rest, and the patient's professional ability, educational ability, social ability and personal life have substantially decreased compared with before illness; (2) At least four of the following symptoms appear at the same time, before the non-fatigue symptoms, and the symptoms persist or recur for at least 6 months: (1) Short-term memory or attention is obviously decreased; (2) sore throat; (3) Enlargement of lymph nodes in neck or armpit; (4) muscle pain; (5) Multiple joint pains, but not accompanied by redness and swelling; (6) Headache, but the attack type, mode and severity are different from before; (7) unable to recover energy after sleep; (8) Discomfort lasts more than 24 hours after exercise.
