National Eating Disorders Association

Traumatic events are events that cause psychological, physical, and/or emotional pain or harm. Traumatic events, especially those involving violence between people, have been found to be significant risk factors for the development of a variety of psychiatric disorders, including eating disorders. Individuals with an eating disorder complicated by trauma and PTSD require treatment for both conditions using a trauma-informed, integrated approach.
