Avoidant/Restrictive Food Intake Disorder (ARFID) is a feeding and eating disorder characterized by a persistent pattern of avoiding or restricting food intake. Unlike other eating disorders, ARFID is not driven by concerns about body weight or shape. Instead, it is driven by sensory sensitivities, fear of aversive consequences such as choking or vomiting, or a general lack of interest in eating. It was formally recognized in the DSM-5 in 2013, replacing the earlier diagnosis of Feeding Disorder of Infancy or Early Childhood.
Research estimates suggest ARFID affects between 0.5% and 5% of the general population, with higher rates in clinical settings. Studies in pediatric populations have found rates as high as 22.5% in children presenting to eating disorder clinics. ARFID is not a childhood-only condition — it persists into adulthood for a significant proportion of those affected, though it remains underdiagnosed in adult populations.
ARFID presents in three primary ways, and many individuals experience a combination. Sensory-based avoidance: individuals avoid foods based on their sensory properties — texture, smell, color, temperature, or appearance. The sensation is not merely unpleasant; for many it is genuinely overwhelming. Fear-based avoidance: driven by fear of a negative outcome such as choking, vomiting, or an allergic reaction, often following a traumatic food-related experience. Low interest or appetite: a general lack of interest in food or eating, often accompanied by forgetting to eat, feeling full quickly, or simply not experiencing hunger cues in the typical way.
ARFID is not picky eating. The clinical distinction is significant: picky eating does not cause nutritional deficiency, weight loss, or marked interference with psychosocial functioning. ARFID does. ARFID is also not a phase, not a choice, and not the result of bad parenting. It is a recognized clinical condition that typically requires professional intervention to address effectively.
ARFID frequently co-occurs with autism spectrum disorder, ADHD, anxiety disorders, and obsessive-compulsive disorder. Research suggests that sensory processing differences — common in autism and ADHD — may contribute to the sensory-based subtype of ARFID. Understanding these overlaps is important for accurate diagnosis and tailored treatment.
