OSFED (Other Specified Feeding or Eating Disorder) debuted in 2013 in the American Psychological Association’s release of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V), but the concept isn’t completely new. Prior to OSFED’s inception, anyone who failed to meet the narrowly defined diagnostic criteria for Anorexia Nervosa or Bulimia Nervosa received an EDNOS diagnosis – “Eating disorder Not Otherwise Specified.”

Over time, EDNOS became a diagnostic dumping ground, serving as a catch-all diagnosis for patients whose symptomology didn’t fall within the strict criteria for one eating disorder in particular. It erroneously earned a reputation as being somehow less severe than other eating disorders, leading many EDNOS patients to feel as though they had fallen short of having a “real” eating disorder.

OSFED can be fatal, and is a not diagnosis to be taken lightly.  The associated risks – electrolyte imbalance, osteoporosis, cardiac abnormalities, dental erosion, etc. – are just as life-threatening as full-threshold Anorexia, Bulimia and Binge Eating disorder. Thus, three years ago the APA decided to do away with EDNOS all together and add several new and distinct eating disorder diagnoses, including OSFED.

OSFED is now the most commonly eating disorder, encompassing an estimated 70 percent of all diagnoses. It’s characterized by abnormal eating patterns, distorted body image and extreme consciousness of weight/shape.  Heightened anxiety around meal times and compulsive exercise are common symptoms.  OSFED consists of (but is not limited to) five primary presentations:

  1. Atypical Anorexia: occurs when all (restricting food, fear of gaining weight) but the weight criteria (less than 85% of what’s expected) are met for Anorexia Nervosa
  2. Atypical Bulimia Nervosa: occurs when all (binge eating, inappropriate compensatory behavior) but the frequency and/or duration (at least once a week for three months) criteria for Bulimia Nervosa are met
  3. Purging Disorder: characterized by frequent and recurring purging episodes in the absence of binge eating
  4. Atypical Binge Eating Disorder: occurs when all (lack of control, eating while feeling full, eating when not hungry, feelings of guilt) but the frequency and/or duration criteria for BED (at least once a week for three months) are met
  5. Night Eating Syndrome: characterized by the consumption of a large percentage of one’s daily caloric intake occurring during the night

As previously stated above, OSFED is a dangerous disease, requiring similar precautions and care to other eating disorder diagnoses. Treatment should involve an interdisciplinary team of professionals, psychoeducation, psychotherapy, cognitive behavioral and dialectical behavioral skill coaching, nutritional counseling and psychopharmacology. Levels of care include the outpatient level, as well as inpatient and residential stays, depending on symptom intensity.
