The Many Faces of Eating Disorders: Anorexia Nervosa (AN), Bulimia Nervosa (BN), Binge Eating Disorder (BED), Other Specified Feeding or Eating Disorder (OSFED), Bulimarexia, and Orthorexia
Feeding and eating disorders (EDs) are severe mental illnesses. This chapter gives a concise overview regarding EDs, their diagnostic configuration, and comorbidity with other mental illnesses. Moreover, the focus included vulnerability and psychological aspects of EDs, with particular attention given to the impact of dysfunctional attachment dynamics and relational trauma on the onset of each type of ED. The chapter covers EDs such as anorexia nervosa, bulimia nervosa, binge eating disorder, and other specified feeding or eating disorder (OSFED). Types of EDs also included those that are not present in Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5), but are frequently found in clinical practice. Such disorders (e.g., bulimarexia or orthorexia) are symptomatological manifestations that require further investigation to clarify risk factors related to their onset and to shed light on their mechanism of action.
