Many new disorders have been identified in the DSM-5 published in 2013. One of them is avoidant/restricted food intake disorder (ARFID). Although this eating disorder was accompanied by significant eating restriction and growth retardation, it is not accompanied by fear of weight gain. Therefore, it was decided to be classified as a separate diagnosis from anorexia nervosa and bulumia nervosa. More studies are needed for the epidemiology of ARFID in children, adults and the elderly. It is known to be seen approximately 3% in the community sample and between 14% and 23% in clinical samples. In addition, it has been found that there is not yet sufficient data on the etiology of ARFID which is yet to be included in diagnostic classifications. Primary health care providers should be aware of ARFID and its various clinical manifestations for early diagnosis, minimizing sequelae and making appropriate interventions. Approaches which promise hope to treatment include modifications to cognitive behavioural therapy (CBT) and family based therapy (FBT). Our purpose in this review is to review the historical development, diagnostic criteria, clinic features and treatment of ARFID in the light of current literature.
