The reason for writing this article is that eating disorders (including anorexia nervosa and bulimia nervosa) are difficult to detect in clinical practice and are not treated in a timely and professional manner. In my clinical work, patients with anorexia nervosa and bulimia nervosa are not uncommon, and most of them are women. When they come to me, they have been going through a lot of trouble, and they have been seeking medical treatment for months or even years. But they still “work tirelessly” and repeat the very hard “work” countless times, in the cycle of “eating” and “vomiting”, “eating” and “not eating”. “Twelve-year-old Xiaoyu is the youngest bulimic I have ever met. She was very bright and had good character, and always ranked first or second in her grade in elementary school. When I saw Xiaoyu, she had been on a diet for almost a year, her weight had dropped from 47 kg to 35 kg, her menstrual flow had stopped just two months earlier, her heartbeat had slowed down in the past two months, and her hair was falling out in large quantities; the child’s nutritional, metabolic and endocrine physiological functions had been affected, and if the situation continued, it was very dangerous, and once the cachexia and organism failure occurred, it would be life-threatening… … Although there is no more accurate and scientific epidemiological survey on the incidence of eating disorders in China, some data show that the prevalence of the disease in the Chinese urban population is almost the same as that in Western countries. The prevalence of eating disorders in Western societies in the post-industrial era, including developing countries in transition, has become a social epidemic, especially in the context of immigrant culture, modernization or urbanization, and the incidence of the disease is increasing year by year. If the disease is prolonged, 5-15% of patients die from nutritional disorders, infections and exhaustion, individual deaths from accidents and suicides, and the prognosis is poor for those with a long duration and number of minimum weight occurrences. In contrast to its potentially high lethality, the knowledge and recognition of the disease by society and even by professionals is low. For this reason, both research and studies in the professional field and knowledge at the societal level appear to be necessary. Both anorexia nervosa and bulimia nervosa have an intrinsic psychosocial component to them. Psychology believes that unresolved subconscious conflicts are the main cause of psychophysiological disorders. Eating is a human instinct, and if a person uses the most instinctive part as a way to express an underlying conflict, life can be challenging. There are plenty of people who use eating and vomiting to relieve stress in their daily lives, just to varying degrees. People with low self-esteem, straitjacketed, stereotypical, obsessive personality traits and perfectionist tendencies are more likely to develop the disorder, as are people who are overly concerned about body size and weight and judge their self-worth by it. Chronic mental stimulation, excessive stress at work and school, maladjustment to new environments, and emotional depression caused by frustration and shock in friendships and families are all predisposing factors for the development of the disorder. Clinical diagnosis is made when eating is significantly lower than normal, weight loss exceeds 15% of the normal average weight, or the body mass index (weight/height2) is less than 17.5 K/m?, there is an overwhelming fear of gaining weight, deliberate weight loss by various means, accompanied by signs and symptoms of endocrine disorders. Different schools of psychotherapeutic theories have different interpretations of eating disorders. The subconscious language is “I don’t want to grow up”. The fear of maturity is because the subconscious mind associates physical maturity with rejection or abandonment; another explanation is the rejection of sexuality and the fear of sex. Another explanation is the rejection of sexuality, the fight against the fear of sex, the denial of the female role in the form of “menopause”. The third explanation is the child’s rebellion against parental authority, the struggle for autonomy, the struggle for self-affirmation in the home, and the struggle against parents. The family systems view is that the individual’s symptoms are closely related to the family environment and family relationships in which he or she lives. Family therapist Minuchin, after studying families with psychosomatic disorders, summarized the common characteristics of families with eating disorders: 1. Entangled family relationships: the family lacks appropriate emotional distance, everyone is deeply involved in each other’s lives, and family members are keen “mind readers”; 2. Overprotective: the family Try to avoid conflict, especially sensitive to the “discomfort” of others, too quickly trying to relieve each other’s stress, so that the family is unable to learn to deal with emotions; 3, extreme rigidity: do not advocate change, trying to maintain the status quo, in a rigid way to deal with various problems in the development of the family; 4, conflict avoidance: the family to avoid the way In the face of various conflicts, especially when the parents’ relationship is poor and the marriage appears stressful, the child gets involved in the parents’ conflict in the form of symptoms, converts the conflict and relieves the marital stress. In short, the eating disorder developed in response to rigid beliefs and role expectations maintains the equilibrium of the rigid family with the eating disorder, and this rigid system tightly binds not only the child but also the other family members. The socio-cultural perspective focuses on the perception of thinness: changes in dietary structure and aesthetic consciousness, the promotion of weight loss and thinness, and the tendency to pursue slenderness and perfectionism reinforce the spread of this consciousness; weight as a symbolic expression of power and control, a “weapon” to cope with a rapidly changing society and to overcome the fear that uncertainty brings to the human heart “Young women under social pressure to give up relationships because of eating disorders, social anxiety about women’s achievements, the guilt that arises when women want to be cared for, etc. I hope that this disease, which is a serious danger to the mind and body, will be better understood, diagnosed and treated early.
