Pathogenesis of anorexia nervosa

Anorexia nervosa is a potentially life-threatening psychiatric disorder that threatens the life and health of the patient. Patients are characterized by a very low body mass index, rapid weight loss, an irrational fear of weight gain, and a distorted view of their body image. The disease is closely related to genetic factors, neuroendocrine imbalances, and psychosocial and family factors. In recent years, its morbidity and mortality rates have gradually increased. The causes of death are not only organ failure due to extreme starvation, but also complications due to overmedication and depression and suicide. Currently, nutritional therapy and psychotherapy are the main treatments for the disease. It is mainly found in the adolescent and female population, and the mortality rate of patients is very high. The study of the pathogenesis of anorexia nervosa is of great importance to actively improve the prognosis and save the lives of patients
