AimThe aim of this paper was to characterise nonspecific eating disorders (other than anorexia nervosa and bulimia nervosa).MethodThe Medline database was searched for articles on nonspecific eating disorders. The following disorders were described: binge eating disorder (BED), pica, rumination disorder, avoidant/restrictive food intake disorder, night eating syndrome (NES), sleep-related eating disorder (SRED), bigorexia, orthorexia, focusing on diagnosis, symptoms, assessment, comorbidities, clinical implications and treatment.ResultsAll of the included disorders may have dangerous consequences, both somatic and psychological. They are often comorbid with other psychiatric disorders. Approximately a few percent of general population can be diagnosed with each disorder, from 0.5-4.7% (SRED) to about 7% (orthorexia). With the growing literature on the subject and changes in DSM-5, clinicians recognise and treat those disorders more often.ConclusionsMore studies have to be conducted in order to differentiate disorders and treat or prevent them appropriately.
