Eating Disorder Types and Diagnosis
The Eating disorder type diagnosis doesn’t simply come down to a doctor’s judgement. In the US, Eating Disorders are diagnosed according to specific criteria laid out in the Diagnostic and Statistical Manual of Mental Disorders (DSM). The latest version, DSM-5, was released in 2013. Medical professionals in Australia generally use the same criteria for their diagnoses.
Over the years, as our understanding has improved, more types of eating disorders have been classified in the DSM 5.
Diagnostic and Statistical Manual of Mental Disorders (DSM–5)
The Diagnostic and Statistical Manual of Mental Disorders (DSM–5) is the product of more than 10 years of effort by hundreds of international experts in all aspects of mental health. Their dedication and hard work have yielded an authoritative volume that defines and classifies mental disorders in order to improve diagnoses, treatment, and research.
The DSM 5 criteria are concise and explicit, intended to facilitate an objective assessment of symptom presentations in a variety of clinical settings—inpatient, outpatient, partial hospital, consultation-liaison, clinical, private practice, and primary care.
While the DSM 5 is a document created by the American (US of A) Psychiatric Association it is used by many in the rest of the world including Australia as a standard for professionals, clinicians, mental health organastions when diagnosing and treating mental health consumers and in clinical research.
Eating and feeding disorders type currently specified in the DSM include:
- Anorexia Nervosa
- Bulimia Nervosa
- Binge Eating Disorder
- Rumination Disorder
- Avoidant/Restrictive Food Intake Disorder (ARFID)
- Other specified Feeding or Eating Disorder (OSFED)
- Unspecified Feeding or Eating Disorder (UFED)
Eating Disorder OSFED and UFED categories
The OSFED and UFED type or categories are used when a patient experiences significant distress as a result of their symptoms, but doesn’t meet the criteria for another Eating Disorder. They don’t necessarily mean the disorder is less severe.
