Eating disorder not otherwise specified (EDNOS) is no longer recognized in the most recent version of the DSM-IV. It has been replaced by Other specified feeding or eating disorder or OSFED.
Eating disorder not otherwise specified is an eating disorder that does not meet the criteria for: anorexia nervosa, bulimia nervosa, ARFID or binge eating. Individuals with EDNOS usually fall into one of three groups: sub-threshold symptoms of anorexia or bulimia, mixed features of both disorders, or extremely atypical eating behaviors that are not characterized by either of the other established disorders.
People with EDNOS have similar symptoms and behaviors to those with anorexia and bulimia, and can face the same dangerous risks.
EDNOS is the most prevalent eating disorder; about 60% of adults treated for eating disorders are diagnosed with EDNOS. EDNOS occurs in both sexes.

Characteristics
Rather than providing specific diagnostic criteria for EDNOS, the fourth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) listed six non-exhaustive example presentations, including individuals who:
- Meet all criteria for anorexia nervosa except their weight falls within the normal range.
- Meet all criteria for bulimia nervosa except they engage in binge eating or purging behaviors less than twice per week or for fewer than three months.
- Purge after eating small amounts of food while retaining a normal body weight.
- Repeatedly chew and spit out large amounts of food without swallowing.
- Do not meet criteria for binge eating disorder.
Despite its subclinical status in DSM-IV, available data suggest that EDNOS is no less severe than the officially recognized DSM-IV eating disorders. In a comprehensive meta-analysis of 125 studies, individuals with EDNOS exhibited similar levels of eating pathology and general psychopathology to those with anorexia nervosa and binge eating disorder, and similar levels of physical health problems as those with anorexia nervosa. Although individuals with bulimia nervosa scored significantly higher than those with EDNOS on measures of eating pathology and general psychopathology, those with EDNOS exhibited more physical health problems than those with bulimia nervosa.

Diagnosis
The three general categories for an EDNOS diagnosis are subthreshold symptoms of anorexia or bulimia, a mixture of both anorexia or bulimia, and eating behaviors that are not particularized by anorexia and bulimia. EDNOS is no longer considered a diagnosis in DSM-5; those displaying symptoms of what would previously have been considered EDNOS are now classified under Other Specified Feeding or Eating Disorder.
Epidemiology
Although EDNOS (formerly called atypical eating disorder) was originally introduced in DSM-III to capture unusual cases, it accounts for up to 60% of cases in eating disorder specialty clinics. EDNOS is an especially prevalent category in populations that have received inadequate research attention such as young children, males, ethnic minorities, and non-Western groups.
