OSFED stands for "Other Specified Feeding or Eating Disorder." It is a diagnostic category in the DSM-5 that is used when an individual's symptoms do not meet the criteria for a specific feeding or eating disorder, but the symptoms cause significant distress or impairment in social, occupational, or other areas of functioning.
An example of OSFED could be an individual who engages in recurrent episodes of binge eating, but does not engage in the compensatory behaviors such as purging or excessive exercise that are required for a diagnosis of bulimia nervosa. Another example could be an individual who restricts their food intake and has a significantly low body weight, but does not meet all of the criteria for anorexia nervosa.
