Eating Disorders Not Otherwise Specified (EDNOS)

Many people suffer from disordered eating but do not fit neatly into the Anorexia Nervosa or Bulimia Nervosa Categories. These people are suffering and they do require treatment. People with disordered eating behaviors that resemble anorexia nervosa or bulimia nervosa but do not meet one or more essential diagnostic criteria may be diagnosed with Other Specified Feeding or Eating Disorder (OSFED). This was previously called (and is still referred to as): Eating Disorders Not Otherwise Specified.

Examples of OSFED include:

  • Atypical anorexia nervosa
  • Subthreshold bulimia nervosa (does not meet full diagnostic criteria)
  • Subthreshold binge eating disorder (does not meet full diagnostic criteria)
  • Purging disorder
  • Night Eating Syndrome:
    *Ingest 25% of daily calories after evening meal
    *Initial insomnia
    *Morning anorexia
    *Tension/irritability in the evening
    *Cognitive distortions about food and weight

Again, one does not need to have a diagnosis of an eating disorder per se to determine that they have disordered eating and/or need treatment.
