Avoidant/restrictive food intake disorder (ARFID) is a feeding or eating disorder in which individuals significantly limit the volume or variety of foods they consume, causing malnutrition, weight loss, or psychosocial problems. Unlike eating disorders such as anorexia nervosa and bulimia, body image disturbance is not a root cause. Individuals with ARFID may have trouble eating due to the sensory characteristics of food, executive dysfunction, fears of choking or vomiting, low appetite, or a combination of these factors. While ARFID is most often associated with low weight, ARFID occurs across the whole weight spectrum.
