Eating Disorder Not Otherwise Specified (EDNOS)

Some people with an eating disorder may have received a diagnosis of Eating Disorder Not Otherwise Specified (EDNOS). This was used in the Diagnostic and Statistical Manual of Mental Disorders (DSM) classification system until 2013. Around 50% of all people diagnosed with an eating disorder were diagnosed with EDNOS and studies suggested that a significant percentage of people with this diagnosis actually had binge eating disorder. The aim of the changes to the classification system in 2013 were to ensure more people with eating disorders have a diagnosis that accurately describes their symptoms and behaviours.

A diagnosis of EDNOS would typically have been given to someone whose symptoms didn’t meet all of the criteria for anorexia or bulimia or where their symptoms were a mix of those for anorexia and bulimia. EDNOS is not a less serious form of an eating disorder. The latest diagnostic criteria no longer uses this term and people would be diagnosed with anorexia, bulimia or binge eating disorder.
