Hannah is being treated for Avoidant/Restrictive Food Intake Disorder, or ARFID. Unlike eating disorders like anorexia or bulimia nervosa, this diagnosis isn’t concerned with body shape or size, said Kate Dansie, clinical director of the Eating Disorder Center in Rockville, Maryland. Instead, people with ARFID are very limited in the foods they feel safe and comfortable eating, Dansie said. Unlike just being “picky,” this disorder can be debilitating and cause long-term health problems.
