- - - - SYMPTOMS
        
        A. Repeated regurgitation of food over a period of at least 1 month. Regurgitated food may be re-chewed, re-swallowed, or spit out.
        
        B. The repeated regurgitation is not attributable to an associated gastrointestinal or other medical condition (e.g., gastro esophageal reflux, pyloric stenosis).
        
        C. The eating disturbance does not occur exclusively during the course of anorexia nervosa, bulimia nervosa, binge-eating disorder, or avoidant/restrictive food intake disorder.
        
        D. If the symptoms occur in the context of another mental disorder (e.g., intellectual disability [Intellectual developmental disorder] or another neurodevelopmental disorder), they are sufficiently severe to warrant additional clinical attention.
  - - - POTENTIAL CAUSES The avoidance and restricting of food may be due to (1) the nutrient’s physical appearance such as the color, texture, or smell of the food; and (2) worrying about negative consequence of eating the food, such as choking or vomiting (DSM-5, 2013). According to DSM-5 (2013), the diagnostic criteria of avoidant/restrictive food intake disorder are:
        
        SYMPTOMS An eating or feeding disturbance (e.g., apparent lack of interest in eating or food; avoidance based on the sensory characteristics of food; concern about aversive consequences of eating) as manifested by persistent failure to meet appropriate nutritional and/or energy needs associated with one (or more) of the following:
        
        Significant nutritional deficiency.
        
        Dependence on enteral feeding or oral nutritional supplements.
        
        Marked interference with psychosocial functioning.
        
        The disturbance is not better explained by lack of available food or by an associated culturally sanctioned practice.
        
        The eating disturbance does not occur exclusively during the course of anorexia nervosa or bulimia nervosa, and there is no evidence of a disturbance in the way in which one’s body weight or shape is experienced.
        
        The eating disturbance is not attributable to a concurrent medical condition or not better explained by another mental disorder. When the eating disturbance occurs in the context of another condition or disorder, the severity of the eating disturbance exceeds that routinely associated with the condition or disorder and warrants additional clinical attention.
        
        Significant weight loss (or failure to achieve expected weight gain or faltering growth in children).
