Diagnostic Criteria of Other Specified Feeding or Eating Disorder (OSFED)
  • Those who have some, but not fit all the criteria of AN, BN and BED.
  • Those who binge and purge irregularly, less than the frequency stated at the diagnostic criteria of BN.
  • People who experience disordered eating or any subclinical symptoms (such as having AN symptoms but still have menstrual cycle)
  • Having compensatory behaviors without binging.

If you fit only some, but not all, of the symptoms mentioned in AN, BN and BED, you may probably be categorized as Other Specified Feeding or Eating Disorder . Actually, Those cases generally occur more often all over the world. It might reflect only the problem of categorization, but did not necessary mean that it is less severe than AN or BN. Therefore, people with Other Specified Feeding or Eating Disorder should not ignore their problems because they are actually standing in the spectrum of eating disorders, swinging from AN to BN or vice versa. Patients with Diagnostic Criteria of Other Specified Feeding or Eating Disorder (OSFED) still need interventions.
