Avoidant/Restrictive Food Intake Disorder

Avoidant/Restrictive Food Intake Disorder - Fussy Feeder Facts

• Extreme picky eating; persistent failure to meet nutritional/energy needs.
• Manifests as ≥1:
  • Significant weight loss or faltering growth (children).
  • Clinically significant nutritional deficiency.
  • Dependence on oral supplements or enteral feeding.
  • Marked psychosocial interference.
• Crucially, no body image distortion (unlike Anorexia/Bulimia).
• Not explained by food unavailability or cultural norms.

⭐ ARFID frequently co-occurs with anxiety disorders, autism spectrum disorder (ASD), and obsessive-compulsive disorder (OCD).

Avoidant/Restrictive Food Intake Disorder - Diagnosis Deep Dive

• Core Criterion A: Persistent eating/feeding disturbance → failure to meet nutritional/energy needs.
• Associated with ≥1 of:
  • Significant weight loss / faltering growth.
  • Nutritional deficiency (e.g., anemia).
  • Dependence on enteral feeding / oral supplements.
  • Marked psychosocial interference.
• Key Exclusions:
  • Not due to lack of food / cultural practice.
  • No body image disturbance (vs. Anorexia/Bulimia).
  • Not solely due to other medical/mental disorder (unless ARFID warrants separate attention).
• Common Presentations:
  • Sensory-based avoidance (texture, smell).
  • Apparent lack of interest in eating.
  • Fear of aversive consequences (choking).

⭐ ARFID frequently co-occurs with anxiety disorders, autism spectrum disorder (ASD), ADHD, and OCD.

Avoidant/Restrictive Food Intake Disorder - Why So Selective?

• Core Reasons (Not Body Image):
  • Sensory sensitivity (texture, smell, taste).
  • Past aversive experiences (choking, pain).
  • Apparent lack of interest in food.
• Associated Conditions:
  • Anxiety disorders, Autism Spectrum Disorder (ASD).
  • Obsessive-Compulsive Disorder (OCD), ADHD.
• Predisposing Factors:
  • Temperament: Food neophobia, high anxiety.
  • Learned feeding difficulties.

⭐ ARFID frequently coexists with anxiety disorders and ASD, unlike anorexia nervosa's focus on body weight/shape.

Avoidant/Restrictive Food Intake Disorder - Rule‑Out Rundown

• Medical Conditions: GI diseases (e.g., GERD, IBD, celiac), food allergies/intolerances, endocrine disorders (e.g., hyperthyroidism), neurological conditions affecting swallowing.
• Other Mental Disorders:
  • Anorexia Nervosa (no body image disturbance in ARFID).
  • Bulimia Nervosa (no bingeing/purging in ARFID).
  • Depression/Anxiety (food avoidance may be secondary).
  • Autism Spectrum Disorder (sensory sensitivities common, but ARFID is primary diagnosis if criteria met).
  • OCD (food rituals not driven by ARFID-specific fears).
  • Somatic Symptom Disorder.
• Normal Picky Eating: Less severe, no significant weight loss/nutritional deficiency/psychosocial impairment.

⭐ ARFID is distinguished from Anorexia Nervosa by the absence of body weight or shape concerns or fear of fatness.

• Lack of Food Availability/Cultural Practices: Not ARFID if explained by these factors alone.
• Substance Use: Appetite suppression from stimulants, etc.

Avoidant/Restrictive Food Intake Disorder - Nourish & Flourish

• Goals: Correct nutritional deficiencies, achieve/maintain healthy weight, expand food repertoire, reduce mealtime anxiety.
• MDT Approach: Physician, Dietitian, Psychologist/Psychiatrist, OT.
• Interventions:
  • Nutritional: Structured meals, gradual caloric ↑. NG tube for severe cases.
  • Behavioral (CBT-AR): Exposure therapy (systematic desensitization), parent training.
  • Pharmacological: Limited role. Treat comorbidities (anxiety). Cyproheptadine (appetite), low-dose olanzapine (rigidity) - use cautiously.
• Prognosis: Variable; early intervention is crucial for better outcomes.

⭐ Unlike Anorexia Nervosa, ARFID treatment focuses on overcoming sensory sensitivities, fear of aversive consequences (e.g., choking), or lack of interest in food, not body image concerns.

High‑Yield Points - ⚡ Biggest Takeaways

• ARFID: Persistent failure to meet nutritional/energy needs; not due to food scarcity or cultural norms.
• Key: No body image disturbance (unlike Anorexia/Bulimia).
• Results in: Weight loss, nutritional deficiency, supplement dependence, or impaired psychosocial function.
• Presents as: Low food interest, sensory aversion, or fear of aversive eating consequences (e.g., choking).
• Onset often in infancy/early childhood; can persist or arise later.
• Distinguish from other eating disorders, medical conditions, and ASD.
