Session Seven – Trauma, Dissociation and Addiction: The Interplay of Eating Disorders and Substance Abuse
Content Level: Advanced

Session Description
This session explores how trauma and dissociation intersect with eating disorders and with substance use disorders. We will examine how dissociation can manifest as a survival strategy in the context of unresolved trauma and how this adaptive process can evolve into complex clinical presentations involving eating disorders and/or addiction. Participants will learn how betrayal trauma, attachment ruptures, and systemic oppression contribute to dissociative adaptations and how these adaptations manifest in clinical symptoms such as food addiction and substance abuse. The session integrates research with clinical applications, emphasizing the need for trauma-informed, dissociation-aware approaches in treating individuals with eating disorders and addictions.
