Other Specified Feeding or Eating Disorder (OSFED)
According to the DSM-5 criteria, to be diagnosed as having OSFED a person must present with a feeding or eating behaviors that cause clinically significant distress and impairment in areas of functioning, but do not meet the full criteria for any of the other feeding and eating disorders.
A diagnosis might then be allocated that specifies a specific reason why the presentation does not meet the specifics of another disorder (e.g. Bulimia Nervosa- low frequency). The following are further examples for OSFED:
- Atypical Anorexia Nervosa: All criteria are met, except despite significant weight loss, the individual’s weight or BMI is within or above the normal range.
- Binge Eating Disorder (of low frequency and/or limited duration): All of the criteria for BED are met, except at a lower frequency and/or for less than three months.
- Bulimia Nervosa (of low frequency and/or limited duration): All of the criteria for Bulimia Nervosa are met, except that the binge eating and inappropriate compensatory behaviour occurs at a lower frequency and/or for less than three months.
- Purging Disorder: Recurrent purging behaviour to influence weight or shape in the absence of binge eating
- Night Eating Syndrome: Recurrent episodes of night eating. Eating after awakening from sleep, or by excessive food consumption after the evening meal. The behavior is not better explained by environmental influences or social norms. The behavior causes significant distress/impairment. The behavior is not better explained by another mental health disorder (e.g. BED).
