Eating disorders (EDs) are complex and difficult-to-treat illnesses that are often chronic and disabling and are characterized by aberrant patterns of feeding behaviour. There are two main disorders: anorexia nervosa (AN) and bulimia nervosa (BN), both characterized by resistance to treatment. Many to most ED patients show persistent core symptoms after treatment, and this could be considered as treatment “resistance.” ED pathogenesis is complex, and it is presumed to be influenced by developmental, social, and biological processes. This chapter reviews the current state of the art for treatment. Given the clinical and public health importance of these disorders, much remains to be in terms of improving ED treatments.
