Other Specified Feeding or Eating Disorders (OSFED) formerly called eating disorder not otherwise specified (EDNOS) is when an individual shows signs of an eating disorder but does not fit the strict diagnostic criteria of anorexia nervosa or bulimia nervosa. OSFED is the most common eating disorder diagnosis making up 40-60% of all cases. Individuals with OSFED may show some signs of either anorexia nervosa or bulimia nervosa, signs of both, or show completely atypical symptoms associated with abnormal eating habits that are not related to either. The majority of individuals with an eating disorder are diagnosed with OSFED rather than a specific condition. Someone who is diagnosed with OSFED may have all the symptoms of anorexia nervosa, but fall into normal weight range or still have a menstrual cycle. Others may show all of the signs for bulimia nervosa, except that they only engage in binging and purging a few times a month or less. Individuals who chew food, but spit it out, or purge after eating only small amounts of food may also be diagnosed as OSFED. These diagnoses may be more specifically defined as bulimia nervosa or anorexia nervosa over time as the person's disorder progresses. There is no clearly defined treatment for OSFED, as it may comprise many different symptoms. However, treatment is likely to include a combination of therapy, medications, and dietary support and is tailored to the individual’s specific strengths and needs. Early diagnosis and intervention is key to a potential full recovery and to prevent more serious health consequences that occur with prolonged illness. If you or someone you know has an eating disorder, it is best to contact your doctor or a trained professional for help.
