An overview of eating and feeding disorders according to the future criteria of the International Classification of Diseases (ICD-11) is presented, including information on differential diagnosis, epidemiology, etiology, pathogenesis as well as therapy. Binge-eating disorder is new and the most frequent eating disorder. While anorexia nervosa and bulimia nervosa mostly affect women, the gender ratio in binge-eating disorder is more balanced. Concerning etiology, socio-cultural, biological and psychological factors are discussed. Cognitive behavioral psychotherapy is the best-validated treatment for all three eating disorders. According to the German guidelines for treatment (2019), focal psychodynamic psychotherapy is also a treatment option for anorexia nervosa. Evidence for the positive effect of psychopharmacologic drugs in the treatment of anorexia nervosa is still lacking. Fluoxetine has been shown to have a limited effect in the treatment of bulimia nervosa.
