Avoidant/restrictive food intake disorder: Overview


What is avoidant/restrictive food intake disorder?

Avoidant/restrictive food intake disorder, or ARFID for short, is an eating disorder that occurs when a child or teen does not eat enough to meet their energy or nutritional needs. This could be for a range of reasons, including concerns about food texture or not feeling well when eating. 

Children and teens with this disorder eat very little food or avoid certain foods. This can result in significant weight loss or a failure to gain weight.

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.

Key points

  • ​A child who has ARFID eats very little food or avoids certain foods for a range of reasons, for example because of concerns about food texture or not feeling well when eating.
  • Some people with ARFID have anxiety disorders that appear as a fear of vomiting or choking.
  • ARFID is not the same as picky eating. It involves having a poor appetite overall,​ rather than a rejection of a few foods, and needs medical attention and psychological care.
  • ARFID usually develops in childhood but can occur in people of all ages.
