Avoidant/restrictive food intake disorder (ARFID): Overview

What is avoidant/restrictive food intake disorder?

Avoidant/restrictive food intake disorder (ARFID) is an eating disorder that occurs when a child or teen doesn’t eat enough to meet their energy or nutritional needs. People with ARFID are not concerned about their body weight, shape or size.

Instead, they avoid foods due to worries about vomiting or choking; or dislike of certain food textures, smells or tastes; or because they are not interested in eating or food. Because of their problems with eating, they may lose weight or not grow as expected.

What causes ARFID?

Not a lot of information is currently known about the causes of ARFID.

Some children and teens with ARFID will struggle with anxiety disorders that appear as a fear of vomiting or choking. Other children and teens may experience eating issues as part of another disorder, for example autism. They would only be diagnosed with ARFID, however, if their food issues were more severe than would be expected with the disorder.

Is ARFID the same as "picky eating"?

No, ARFID is not the same as "picky eating".

• Children with ARFID may refuse to eat foods of a certain texture, colour, taste, temperature or smell. Picky eating typically involves only a few foods.
• If a child has ARFID, they tend to have a poor appetite and experience delayed growth. So-called picky eaters have a normal appetite, eat enough food overall and develop normally.
• The problems that people with ARFID develop with food continue for a long time and need medical attention and psychological care. The eating patterns found among picky eaters usually resolve on their own eventually.

Who is affected by ARFID?

ARFID typically begins during childhood but can occur in people of all ages. Unlike those with anorexia nervosa or bulimia nervosa, people with ARFID do not have body image concerns or fears about gaining weight.
