Formerly categorized as Eating Disorder Not Otherwise Specified (EDNOS), the Other Specified Feeding and Eating Disorder diagnosis is applied when an individual’s symptoms cause significant distress but do not fit neatly within the strict criteria of other eating disorders.
Anorexia, bulimia, and binge eating disorder are diagnosed according to a list of expected behavioural, psychological, and physical symptoms. Sometimes a person’s symptoms don’t exactly fit the expected symptoms for any of these three specific eating disorders. In that case, they might be diagnosed with an “other specified feeding or eating disorder” (OSFED).
OSFED is the most common eating disorder diagnosis made in most outpatient settings, the prevalence of OSFED in the community is not clear, never the less it is a very serious condition. Although anorexia and bulimia tend to get the attention, EDNOS actually makes up 70 percent of all 24 million eating disorder diagnoses in the United States. A person with EDNOS may be diagnosed as such because she does not fully meet the criteria for anorexia or bulimia.
