Avoidant / Restrictive Food Intake Disorder (ARFID) synonyms

Avoidant/Restrictive Food Intake Disorder (ARFID) is officially recognized under this name in the DSM-5, though it was previously categorized under various outdated terms such as "Selective Eating Disorder" or "Feeding Disorder of Infancy or Early Childhood." These synonyms are often encountered in older medical literature or by patients seeking clarity on their diagnosis, but Avoidant/Restrictive Food Intake Disorder (ARFID) is the current standard nomenclature used by clinicians worldwide.

What are the historical and alternative names for ARFID?

Before the formal adoption of Avoidant/Restrictive Food Intake Disorder (ARFID) in 2013, clinicians used a variety of descriptive terms to characterize patients with severe food selectivity or phobic responses to eating. Because the condition encompasses diverse presentations—ranging from sensory sensitivity to fear of aversive consequences like choking—medical literature previously used fragmented terminology that did not capture the full scope of Avoidant/Restrictive Food Intake Disorder (ARFID).

Why does the terminology for this condition vary?

The evolution of names reflects a shift in clinical understanding. Older terms were often specific to age groups or single symptoms, whereas Avoidant/Restrictive Food Intake Disorder (ARFID) was established to provide a unified diagnostic framework. Common names you may encounter include:

• Selective Eating Disorder (SED): Often used to describe picky eating that persists into adulthood.


• Feeding Disorder of Infancy or Early Childhood: The DSM-IV classification that preceded the current diagnosis.


• Functional Dysphagia: Occasionally used when the avoidance is rooted in a fear of choking or vomiting.


• Psychogenic Dysphagia: An older term for eating avoidance linked to perceived swallowing difficulties.

How is the condition classified in medical systems?

In international medical systems, Avoidant/Restrictive Food Intake Disorder (ARFID) is now the standard clinical entry. While the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) formalized the name, the ICD-11 (International Classification of Diseases) also utilizes this terminology to ensure global consistency. At DiseaseMaps.org, we have observed 25 individuals navigating this diagnosis, highlighting the importance of using the contemporary Avoidant/Restrictive Food Intake Disorder (ARFID) term to access updated support and research.
