Avoidant/Restrictive Food Intake Disorder

Avoidant/Restrictive Food Intake Disorder (ARFID) Guide

What is Avoidant/Restrictive Food Intake Disorder (ARFID)?

ARFID is an eating disorder characterized by persistent failure to meet appropriate nutritional and/or energy needs associated with one or more of the following: significant weight loss (or failure to achieve expected weight gain or faltering growth in children); significant nutritional deficiency; dependence on enteral feeding or oral nutritional supplements; marked interference with psychosocial functioning. Unlike anorexia nervosa or bulimia nervosa, ARFID does not involve distress about body shape or weight. 

Classification 

ARFID is classified as an eating disorder, a mental health condition that involves unhealthy eating habits and distorted thoughts and emotions related to food, weight, and body shape. It’s a serious condition that can lead to significant physical and psychological health problems.

Statistics

The exact prevalence of ARFID is unknown, as it’s a relatively newly defined disorder. Studies suggest it affects both children and adults, and may be more common in males than females, unlike other eating disorders. Research indicates that ARFID accounts for a significant proportion of eating disorder cases, particularly in younger populations.

Types of Avoidant/Restrictive Food Intake Disorder (ARFID)

There aren’t formally distinct “types” of ARFID, but the reasons for restricted eating can vary:

• Sensory sensitivity: Avoidance based on the sensory characteristics of food (texture, smell, taste).
• Fear of aversive consequences: Avoidance due to past negative experiences with food, such as choking or vomiting.
• Apparent lack of interest in eating or food: Low appetite or disinterest without sensory or fear-based reasons.

Health Signs and Symptoms

Early signs can be subtle. Look for:

• Dramatic weight loss or failure to gain weight as expected.
• Restricted range of preferred foods that becomes progressively narrower.
• Complaints about stomach aches or other physical symptoms around mealtimes.
• Fear of choking or vomiting.
• Lack of interest in food or eating.

Common signs and symptoms include

• Significant weight loss.
• Nutritional deficiencies (e.g., vitamin or mineral deficiencies).
• Fatigue.
• Dizziness or fainting.
• Difficulty concentrating.
• Cold intolerance.
• Social withdrawal or isolation related to mealtimes.

Anatomy and Physiology

ARFID primarily affects the digestive system (leading to potential issues with nutrient absorption and metabolism) and can have widespread effects on other systems due to malnutrition, impacting growth, development, and overall organ function.

Causes

The exact cause of ARFID is unknown, but several factors may contribute:

• Genetic predisposition: Individuals with a family history of eating disorders or anxiety may be at higher risk.
• Temperamental factors: Anxiety, perfectionism, and sensory sensitivities can play a role.
• Environmental factors: Traumatic experiences with food (choking, vomiting), medical conditions affecting appetite, or social pressures related to eating can contribute.

Avoidant/Restrictive Food Intake Disorder (ARFID) Stages: ARFID doesn’t have formal stages, but the severity can be described as:

• Mild: Minimal impact on physical health and daily functioning.
• Moderate: Noticeable weight loss, some nutritional deficiencies, and moderate interference with daily life.
• Severe: Significant weight loss, severe nutritional deficiencies, significant impairment in physical and psychosocial functioning, potential medical complications.

Prevention

While ARFID can’t always be prevented, promoting healthy eating habits from a young age, addressing sensory sensitivities early, and creating a supportive environment around mealtimes can be helpful.

Avoidant/Restrictive Food Intake Disorder (ARFID) Diagnosis: Diagnosis involves a comprehensive evaluation, including a medical history, physical examination, and psychological assessment.

Tests & Examinations

• Physical examination to assess weight, height, vital signs, and overall physical health.
• Blood tests to check for nutritional deficiencies.
• Psychological evaluation to assess eating behaviors, thoughts, and emotions.

Health Professionals

• Physicians: To assess physical health and manage medical complications.
• Psychiatrists/Psychologists: To provide psychological therapy and address underlying emotional issues.
• Registered Dietitians: To develop meal plans and address nutritional deficiencies.
• Occupational Therapists: Can help with sensory sensitivities related to food.

Reasons to see a Professional

• Significant weight loss or failure to gain weight.
• Restricted eating patterns.
• Concerns about nutritional deficiencies.
• Distress or anxiety related to eating.
• Impact on social or occupational functioning.

Process to find the right professional: Seek referrals from your primary care physician, mental health professionals, or online directories specializing in eating disorders.

Visit Preparation: Prepare a list of symptoms, concerns, and questions. Bring a record of eating patterns and any relevant medical history.

Questions to ask:

• What is your experience treating ARFID?
• What treatment approaches do you recommend?
• What are the potential risks and benefits of treatment?
• How often will we meet?

Diagnosis

Diagnosis is based on DSM-5 criteria, which include persistent restriction of food intake, significant weight loss or nutritional deficiency, dependence on supplemental feeding, and interference with psychosocial functioning, without body image disturbance.

Procedures

The diagnostic process may involve physical exams, blood tests, and psychological assessments.

Treatments:

• Nutritional rehabilitation: To restore healthy weight and address nutritional deficiencies.
• Psychotherapy: Cognitive behavioral therapy (CBT) and family-based therapy (FBT) can be effective in addressing underlying emotional issues and changing eating behaviors.
• Occupational therapy: Can help with sensory sensitivities.

Health Monitoring

Regular check-ups with medical and mental health professionals are crucial. Monitoring weight, eating patterns, and psychological well-being is essential. Home devices are not typically used for ARFID monitoring, but tracking food intake and weight (as advised by professionals) can be part of the process.

How to manage Avoidant/Restrictive Food Intake Disorder (ARFID):

• Work closely with a treatment team.
• Adhere to meal plans and therapy recommendations.
• Develop coping strategies for dealing with anxiety or distress related to eating.
• Build a support network.
