Individuals with anorexia nervosa (AN) have high levels of gastrointestinal (GI) symptoms, functional GI disorders, and alterations in interoception. The primary aims of the current study were to determine (1) whether individuals with AN differed in gastric physiology as measured by electrogastrography (EGG) as compared to healthy individuals and (2) whether their EGG activity changed from pre- to post-weight restoration.
