This chapter explores parts or ego states somewhere in the middle of the two that are invested in one or the other form of eating disorder (ED). “Ego state” and “part” are used interchangeably in this chapter. The chapter provides a short neurological explanation of ego states, their purpose, and the difference between dysfunctional and dissociated ego states. It provides an overview of various traditions of parts, which, although not exhaustive, can uncover the common and universal characteristics of ego state work. EDs are very difficult to treat in that they demand attention on so many levels: psychological, emotional, physical, behavioral. The authors believe that it is the reality of dissociation that makes this work all the more difficult, a reality that demands an invitation to all parts of our client to come together and collaborate in the service of healing.

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.
Overwhelming evidence exists that traumatic experiences leave traces in our minds and bodies. Traumatic experiences such as sexual, physical, and emotional abuse have a negative impact on our capacities to relate to and trust other people, but also on the neurobiological functioning of our brain and thus our mind. They also affect our immune systems. Hence, traumatic experiences make dealing with emotions, both positive and negative, quite challenging. In this chapter, a “state-of-the-art” review reveals the presence of a wide variety of traumatic experiences and their consequences in anorexia nervosa, bulimia nervosa, and binge eating disorder patients. Almost all studies investigated the association of retrospectively reported childhood abuse with current ED symptoms using cross-sectional designs. A special focus is on the presence of dissociation in ED patients, as it is one of the main characteristics in EDs with severe trauma.
