Chinese Expert Consensus on the Diagnosis and Treatment of Anorexia Nervosa

Anorexia nervosa (AN) is a type of eating disorders characterized by self-starvation, significant loss of body mass, and malnutrition. AN has the highest mortality rate among all psychiatric disorders, leading to severe psychopathologic symptoms and life-threatening medical complications. However, AN cannot be recognized and diagnosed early in China, resulting in a prolonged course of the disease. Therefore, under the organization of the Eating Disorders Coordination Group of the Psychosomatic Medicine Society of the Chinese Medical Association, together with the Eating Disorders Research Collaboration Group of the Psychiatric Medicine Society of the Chinese Medical Association, this expert consensus was formulated by 16 medical experts based on evidence-based medical evidence, domestic and international guidelines and expert consensus, expert experience, etc., in order to improve the recognition, diagnosis and treatment of AN among domestic professionals.
