Eating disorders (EDs) require a multidisciplinary approach, rather than a hammer-and-nail perspective. Based upon recent research and more than a decade of clinical experience, this article highlights the need to include a trauma-informed and dissociation-sensitive treatment of EDs. The emphasis is on EDs as a dissociative coping strategy, created in many cases to tolerate the intolerable. Ego state therapy, Gestalt principles, and empty chair technique support the adaptive information processing (AIP) of eye movement desensitization and reprocessing (EMDR) in both metabolizing painful experiences that give rise to EDs and in loosening the stranglehold of anxiety and shame. The acronym RUG-C introduces four universal principles in working with ego states: recognition, understanding, gratitude and goal setting, and collaboration. Relational ruptures between ego states/parts of the client (intrapsychic) and between the client and the world (interpersonal) are created in the client’s efforts to deal with painful experiences both large and small. They are repaired in the therapeutic relationship, in the processing of past trauma, and in the rescue of body image from the power of shame. Three case reports, with transcripts, are provided to illustrate conceptualization and its application.
