Avoidant/Restrictive Food Intake Disorder (ARFID):

A Comprehensive Guide to Understanding, Assessment and Treatment Eating Disorders

As a highly experienced clinical medical hypnotherapist, psychotherapist, counsellor and registered nutritionist incorporating functional medicine, I have over 20 years’ experience supporting children and adults to overcome complex challenges. Based in Limerick, Adare, Newcastle West (Limerick), Dungarven, Cork and Youghal (Cork) – as well as offering nationwide online services – I provide integrated, evidence-based care in hypnotherapy, psychotherapy, counselling and nutritional therapy. Whether you are searching for a Clinical Medical Hypnotherapist, Registered Nutritionist, a therapist in Limerick, an Integrative psychotherapist in Cork, or ONLINE counselling services in Youghal, this guide will explain how our tailored approach can help you or your loved one navigate ARFID and minimise its profound impact on health and wellbeing.

What Is ARFID?

Avoidant/Restrictive Food Intake Disorder (ARFID) is a serious eating and feeding disorder marked by persistent avoidance or restriction of particular foods, leading to significant nutritional deficiency, weight loss or faltering growth in children. Unlike anorexia or bulimia,  ARFID is not motivated by concerns about body shape or weight, but by:

  • Sensory sensitivities (texture, taste, smell or appearance of food)

  • Fear of aversive consequences (choking, vomiting, allergic reactions)

  • Lack of interest in eating

  • A combination of these factors

ARFID can present differently in children and adults, but the underlying avoidance pattern and resultant health risks are consistent across age groups (DSM-5, 2013). Early identification and targeted intervention are crucial to prevent acute and chronic medical complications.

ARFID Subtypes

  1. Sensory Subtype
    – Avoidance based on food texture, taste or smell
    – Often results in an extremely limited diet

  2. Fearful Subtype
    – Driven by anxiety about choking, vomiting or allergic reactions
    – May generalise to most foods

  3. Lack-of-Interest Subtype
    – Apparent indifference to food and mealtimes
    – Frequently seen in neurodiverse children and adults

  4. Combination Subtype
    – Mix of sensory sensitivities, fear and lack of interest

Individuals with ARFID may fall into one or more of these categories, shaping a bespoke treatment plan that addresses the specific drivers of avoidance.

ARFID in Children vs. Adults

Studies estimate ARFID prevalence in children and adolescents to be up to 18%, compared to 0.3–2% in adults (Bryant-Waugh et al., 2019¹). In children, ARFID can manifest as:

  • Failure to thrive or faltering growth

  • Delayed developmental milestones

  • Social withdrawal (avoiding family meals or birthday parties)

In adults, chronic malnutrition may result in:

  • Osteoporosis and fractures

  • Anaemia and fatigue

  • Occupational impairment and isolation

Early intervention—particularly in paediatric cases—is vital to reduce long-term morbidity.

ARFID vs. ‘Picky Eating’

While many children outgrow picky eating, ARFID represents a pervasive, persistent avoidance that:

  • Leads to nutritional deficiencies requiring supplementation

  • Is driven by anxiety or sensory processing issues, not mere preference

  • Significantly impairs daily functioning

If your child’s dietary repertoire remains extremely limited beyond early childhood, or if avoidance is causing weight loss, medical review and specialist support are essential.

Causes and Co-Occurring Conditions

ARFID aetiology is multifactorial, including:

  • Heightened sensory sensitivity (taste, texture, smell)

  • Altered appetite regulation

  • Elevated fear-responsiveness

  • Co-morbid mental health conditions: anxiety disorder, OCD, ADHD, ASD

  • Physical health issues: gastro-oesophageal reflux, food allergies (Kuschner et al., 2019²)

A thorough assessment by a multidisciplinary team is necessary to identify all contributing factors.

Physical and Psychological Impact

Left untreated, ARFID can have serious consequences:

  • Growth stunting, delayed puberty and altered bone health (Norris et al., 2018³)

  • Micro- and macro-nutrient deficiencies, anaemia and immunodeficiency

  • Tube feeding dependence or long-term supplement reliance

  • Anxiety, depression, low mood, low energy, stress and social isolation

Our nutritionist and mental health services in Adare, Newcastle West Limerick, Cork, Counselling services in Youghal Cork and ONLINE therapy provide integrated care to address both the physical and emotional dimensions of ARFID.

Diagnosis: Meeting DSM-5 Criteria

To diagnose ARFID, four criteria must be met (DSM-5, 2013⁴):

  1. Persistent avoidance/restriction of food intake resulting in:

    • Significant weight loss or failure to grow

    • Nutritional deficiencies

    • Dependence on supplements

    • Psychosocial impairment

  2. Not attributable to cultural practices or food availability

  3. No evidence of body image concerns typical of other eating disorders

  4. Not better explained by a medical or psychiatric condition

Accurate diagnosis requires collaboration between:

  • Medical practitioners (to rule out organic causes)

  • Nutritionists (to assess dietary adequacy)

  • Psychotherapists (to explore underlying fears and sensory issues)

Evidence-Based Treatments

1. Clinical Medical Hypnotherapy & Hypnosis

By accessing the subconscious mind, hypnotherapy can:

  • Reduce anxiety around feared foods

  • Modify sensory perceptions, making foods more tolerable

  • Strengthen positive associations with eating

As a Clinical Medical Hypnotherapist,  and therapist in Newcastle West (Limerick) , and  Hypnotherapy Clinics in Midleton, Youghal Fermoy Cork with 20+ years’  vast clinical experience in Nutrition, Hypnotherapy, Counselling and Clinical Medical Hypnotherapy expertise, I tailor hypnotherapy and hypnosis interventions to each client’s subtype of ARFID, promoting gradual, gentle sustainable and lasting change.

2. Psychotherapy & Counselling Limerick Cork and ONLINE

Our psychotherapist and Nutritionist specialising in eating disorders employs:

  • Cognitive-Behavioural Therapy (CBT) to reframe catastrophic food fears

  • Gentle and Gradual Exposure therapy to desensitise sensory reactions, mentally emotionally and physically

  • Family therapy to support parents in establishing healthy mealtime routines

Children, adolescents and adults benefit from a warm, empathetic therapeutic alliance that fosters trust and confidence.

3. Functional Medicine Nutritionist Services

As a registered nutritionist using functional medicine principles, I conduct in-depth assessments of:

  • Gut-brain axis health

  • Micronutrient status (e.g., iron, zinc, vitamin D etc )

  • Food intolerances and sensitivities

Personalised meal plans and targeted supplements restore nutritional balance, support digestive function and enhance overall wellbeing.
