ARFID in children

ARFID doesn't look the same in every child. Some children eat a very small number of foods (sometimes fewer than ten) and refuse everything else. Some eat adequate calories from a narrow range but are missing entire food groups. Some have such low interest in eating that they simply don't eat enough to grow. Some have intense fear around specific foods or eating situations.

The common thread is that the restriction is persistent, severe, and isn't about body image. Many parents describe years of 'extreme fussy eating' that never improved, mealtime battles, food-related anxiety, and social difficulties - can't eat at friends' houses, parties are stressful, school lunches are impossible.

Children with ARFID often describe their experience differently from how parents see it. They may say certain foods make them feel sick, or they're scared of trying new things, or they just don't feel hungry. Taking the child's perspective seriously is an important part of assessment and treatment.

ARFID is diagnosed by a clinical assessment, not a single test. I look at the pattern of restriction (what foods are accepted, what's avoided, and the reasons behind it), the history (when did restriction start, has it got better or worse, what's been tried), and the impact (on weight, growth, nutritional status, and psychosocial functioning).

Other conditions need to be ruled out or identified. Coeliac disease, eosinophilic oesophagitis, food allergies, GI conditions, and other medical causes of poor appetite or food avoidance all need considering. ARFID can also coexist with autism - in fact, the overlap is significant - and with anxiety disorders.

ARFID management is multidisciplinary and takes time. There's no quick fix, but meaningful progress is genuinely possible, especially when treatment starts earlier rather than later. The main approaches currently used are:

Nutritional rehabilitation: my primary role. Making sure the child is nutritionally adequate despite the restricted diet, using supplementation where needed, and creating the conditions for food expansion. Sometimes oral nutritional supplements, occasionally tube feeding for severe cases where weight or health is at risk.

CBT-AR (Cognitive Behavioural Therapy for ARFID): a specific psychological approach developed for ARFID, recognised within the NICE eating disorders guideline. It addresses the maintaining factors - sensory sensitivity, fear, or low interest - through structured exposure and cognitive work. The evidence base is growing and the results are encouraging.

Systematic desensitisation and food chaining: gradual, structured exposure to new foods, often working through a hierarchy from looking at a food, to touching it, smelling it, and eventually tasting it. Food chaining links new foods to existing safe foods based on shared sensory properties. This is slow, careful work done at the child's pace.

Family involvement is essential. Parents need to understand the condition, manage their own anxiety around their child's eating, and create a home environment that supports rather than pressures. That's not a criticism - it's a recognition that ARFID affects the whole family, and recovery involves the whole family too.

A significant proportion of children with ARFID also have autism, ADHD, anxiety disorders, or a combination. The overlap with autism is particularly well-documented - as the National Autistic Society notes, sensory-driven food avoidance is common in autism and frequently meets ARFID criteria.

Having both conditions doesn't fundamentally change the treatment approach (protect safe foods, ensure nutritional adequacy, expand gradually), but it does affect how treatment is delivered. Autistic children may need adaptations - more visual structure, more predictability, different communication approaches. The pace of food expansion may be slower, and the endpoint may look different from what's expected for a neurotypical child.

Anxiety - whether general anxiety, specific phobias around food, or anxiety about eating in social situations - is another common co-occurrence. When anxiety is a major driver of the restriction, psychological input is particularly important alongside the dietetic work. I often work alongside clinical psychologists or CAMHS services for these children.
