Eating disorders are associated with alterations of the autonomic nervous system (ANS).
Here we aimed to review the current evidence on ANS dysfuntion indexed by measures of heart rate variability (HRV) in Bulimia Nervosa (BN).
BN is characterized by increased resting state vagally-mediated HRV and an impaired stress-response.
Intervention-studies suggest that altered ANS activity in BN is at least partially reversible.
Future studies on the complex relation between BN and HRV should investigate the effect of comorbid disorders, different subtypes of BN, and mechanisms affecting treatment outcome
