Eating disorder not otherwise specified (EDNOS) involves disordered eating patterns. EDNOS is described in the DSM-IV-TR as a "category [of] disorders of eating that do not meet the criteria for any specific eating disorder".
This category is frequently used for people who meet some, but not all, of the diagnostic criteria for anorexia nervosa, bulimia nervosa or binge eating disorder. For example, a person who shows almost all of the symptoms of anorexia nervosa, but who still has a normal menstrual cycle and/or body mass index, can be diagnosed with EDNOS. Or someone that restricts and shows most of the symptoms of anorexia but has occasional episodes of binging without purging. A sufferer may experience episodes of binging and purging, but may not do so frequently enough to warrant a diagnosis of bulimia nervosa. A person may also engage in binging episodes without the use of inappropriate compensatory behaviors; this is referred to as binge eating disorder.
People diagnosed with EDNOS may frequently switch between different eating patterns, or may with time fit all diagnostic criteria for anorexia or bulimia.
People who eat a normal amount of food, but become exceedingly obsessed with healthy eating, or strictly categorize normal foods or entire food groups as "safe" and "off-limits", may be referred to as having orthorexia. However, this diagnosis is not formally accepted by the psychiatric community.
