The short answer
ARFID is a restrictive eating pattern that leads to weight loss or poor growth, nutritional deficiency, dependence on supplements or tube feeding, or marked psychosocial interference, without the body image concerns seen in anorexia. Assessment covers the eating pattern, its drivers, medical and nutritional safety, and other explanations.
What to establish
- A persistent eating or feeding disturbance with one or more consequences: significant weight loss or failure to gain expected weight or growth in children, nutritional deficiency, dependence on enteral feeding or oral supplements, or marked interference with psychosocial functioning.
- It isn't explained by lack of food or a culturally sanctioned practice.
- It doesn't occur only during anorexia or bulimia, and there's no disturbance in how body weight or shape is experienced.
- It isn't better explained by a medical condition or another mental disorder, or, if one is present, the eating problem is more severe than usually expected with it. Weight loss is not required.
The three common drivers
These often overlap, and naming them guides treatment.
- Sensory sensitivity: strong reactions to taste, texture, smell or appearance of food.
- Fear of aversive consequences: fear of choking, vomiting or pain, often after a frightening experience.
- Low interest in eating or food: little appetite or enjoyment.
Medical and nutritional safety
Check weight, height and growth trends, vital signs, and intake. Coordinate with the client's medical provider for laboratory testing and nutritional assessment, and escalate quickly if there are signs of medical instability or refeeding risk.
Differentials and co-occurring conditions
- Anorexia nervosa (look for weight or shape concerns).
- Gastrointestinal, allergic or swallowing problems.
- Anxiety disorders, OCD and depression.
- Autism, which often co-occurs with ARFID but doesn't by itself exclude it.
Frequently asked questions
Is ARFID just picky eating?
No. Many children are picky eaters, but ARFID causes real consequences such as weight loss, poor growth, nutritional deficiency, supplement dependence or major disruption to daily life.
Does ARFID require weight loss?
No. Nutritional deficiency, supplement or tube-feeding dependence, or marked psychosocial interference can also meet the criterion.
Can autistic clients be diagnosed with ARFID?
Yes. Autism and ARFID often co-occur. ARFID is diagnosed when the eating problem is more severe than would usually be expected with autism alone.
