What is ARFID?

Avoidant/restrictive food intake disorder, also known as ARFID, is an eating disorder or feeding disturbance that is characterized by a persistent failure to meet appropriate nutritional and/or energy needs. ARFID is often associated with a psychiatric co-morbidity, especially anxiety and obsessive compulsive disorder. This condition affects both genders and is more common in children and young adolescents; however, it can occur in late adolescence and adulthood as well.

ARFID Causes

Like other eating disorders and disturbances, there is no singular cause of avoidant/restrictive food intake disorder (ARFID). Parents and caregivers of patients who are exhibiting symptoms of ARFID may contribute their condition to being extremely picky about their food choices. But studies show that a major cause of ARFID could be biological [1]. The evolving scientific research about ARFID suggests that this pattern of disordered eating can develop from a complex interplay between genetic, psychological and sociocultural factors.

Understanding the cause of ARFID guides treatment, however, a course of action for patients experiencing ARFID will also be based on their individual symptoms.

Genetic Factors of ARFID

One major influence on the cause of eating disorders is found is genetic factors. Eating disorders are familial illnesses, and temperamental traits predisposing individuals toward developing an illness are passed from generation to generation.

Molecular Hereditary

Like many mental health conditions, hereditary can be a cause for some eating disorder behaviors. Every human is born with a genetic code, which may exhibit patterns in certain health conditions [1], such as ARFID.
[1] https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6378634/

Environmental Influence

Another genetic factor that might cause an individual to experience symptoms of ARFID is an environmental influence from family members. This can come from meal preparation, observing family members’ behaviors with food and exposure to diets and/or restrictive eating in the home [2].
[2] https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6534269/

Sociocultural Factors of ARFID

Another cause of ARFID and other eating disorders can be sociocultural factors. Cultural pressures to eat clean/pure/healthy as well as increased interests in food processing, sourcing, packing and the environmental impact can influence food beliefs and intake.

Healthy Appearance Expectations

In many cultures and in society today, there is oftentimes a misconnection that looking thin is the equivalent of being healthy [3]. This is a common cause of anorexia nervosa, which can co-occur with ARFID.

Food Beliefs

Another sociocultural factor that can be seen in those struggling with ARFID symptoms is food beliefs. This can include moral beliefs about eating meat and dairy, or how these food items are prepared.

Psychological Factors of ARFID

Anxiety and obsessive compulsive disorder symptoms tend to accompany eating disturbances, as do co-occurring mood and anxiety disorders.

Obsessive Compulsive Disorder

For many patients, symptoms of the ARFID eating disorder can co-occur with OCD, also known as Obsessive Compulsive Disorder. In some more extreme cases, obsessions with food intake or preparation can lead to ritualistic compulsions. [4]

Anxiety

Anxiety can be another cause of ARFID, specifically in patients who experience anxiety or fear around eating. They may avoid eating out of fear that they will choke, vomit or even die if they eat certain foods. [5]

Symptoms of ARFID

Avoidant/restrictive food intake disorder, also known as ARFID, is an eating disorder or feeding disturbance that affects young children and adolescents as well as adults. ARFID symptoms vary widely and can evolve with the developmental context of the individual. Common symptoms may include avoidant sensory triggers, restrictive eating habits and fear-based eating experiences.

Knowing the warning signs and symptoms of ARFID is an important first step in seeking care for this type of eating disorder.

Types of ARFID

Like other eating disorder conditions, there are several different types of ARFID, depending on the symptoms the individual is experiencing. The types of ARFID include: Avoidant, Aversive, Restrictive, Adult ARFID and ARFID “Plus.”

Avoidant

One common type of ARFID is Avoidant. In this condition, individuals simply avoid certain types of foods in relation to sensory features, causing a sensitivity or over stimulation reaction. These patients may feel sensitive to the smell of foods; textures, including soft foods or fruit and vegetables that have prickly or defined textures; or general appearance, including color.

Aversive

Another type of the ARFID eating disorder is Aversive. Individuals whose food refusal is related to the Aversive type may experience on fear-based reactions. Aversive ARFID evokes a fear of choking, nausea, vomiting, pain and/or swallowing, forcing the individual to avoid the food altogether.

Restrictive

Individuals who experience Restrictive ARFID may show signs of little-to-no interest in food. Restrictive ARFID can make one forget to eat altogether, show signs of a low appetite or get extremely distracted during mealtime. Another symptom of Restrictive includes extreme pickiness of foods, resulting in limited intake.

Adult ARFID

Symptoms of ARFID not only take place in children and adolescents; in fact, many adults can show signs of ARFID. Individuals with ARFID in their adult years may still have symptoms that were experienced in their adolescent years and can be categorized as Avoidant, Aversive or Restrictive types of ARFID. ARFID symptoms in adults can include selective or extremely picky eating, food peculiarities, texture, color or taste aversions related to food.

ARFID "Plus"

Individuals who are experiencing more than one type of ARFID can begin to develop features of anorexia nervosa, including concerns about body weight and size, fear of weight gain, negativity about fatness, negative body image without body image distortion and preference for less calorie-dense foods. This combination of symptoms is categorized as ARFID “Plus,” a co-occurring eating disorder.

ARFID in Children

Lack of interest in food

Although ARFID can affect individuals of any gender or age, this eating disorder can be more common in children and adolescents. One warning sign of ARFID is the lack of interest in food.

Fear-based food restriction

Children who show symptoms of ARFID might avoid certain foods out of fear of texture, smell or appearance, [1] or construct feelings of fear that a certain food may cause them to vomit/feel sick or choke.

Limiting food intake

Children who experience ARFID can generally limit their food intake for an array of reasons. As explained above, this can be due to a certain fear of food, but it can also come in the form of fasting behaviors.[2]

[2] https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6281436/

ARFID in Adults

Inflexible eating behaviors

When it comes to identifying ARFID symptoms in adults, one common warning sign is inflexible eating behaviors, which can be categorized as one being extremely “picky” with food selection. There is a clear distinction between food preferences in healthy adults versus inflexible eating behaviors found in ARFID-diagnosed individuals, including refusing to try different or new types of food, extremely specific preparation of food choices, and sensitivity to the sensory one perceives from a food, whether physical or emotional. These ARFID symptoms evoke inflexible eating behaviors that can cause attitudes of anorexia nervosa or bulimia. [3]

Fear-based food restriction

Another common symptom of ARFID in adults is fear-based food restriction. Individuals who experience distress about certain foods can have an emotional or physical reaction due to thoughts of an allergic reaction, choking or vomiting [3]. This can cause individuals to avoid certain foods and/or textures, depleting the individual of nutritional value. Fear-based food restriction can also result in low body weight due to anorexia nervosa behaviors and increased anxiety around food. [4]

ARFID Health Risks

There are a number of serious health risks associated with avoidant/restrictive food intake disorder (ARFID), including:

  • Weight loss or being severely underweight
  • Nutritional deficiencies (e.g., anemia or iron deficiency) and malnutrition that can be characterized by fatigue, weakness, brittle nails, dry hair, hair loss, difficulty concentrating, and reduction in bone density
  • Growth failure in adolescents or an increased risk to not thrive; stunted growth or falling off growth curves for weight and height

ARFID vs. Anorexia

ARFID is often confused with anorexia nervosa because weight loss and nutritional deficiency are common shared symptoms between the two disorders. However, the primary difference between ARFID and anorexia is that ARFID lacks the drive for thinness that is so common for individuals with anorexia.

ARFID Health Risks are Similar to Anorexia Risks

Complications associated with ARFID may mirror the health risks of anorexia nervosa for low-weight patients. These risks include:

  • Cardiac complications
  • Heart problems
  • Kidney and liver failure
  • Bone density loss/osteoporosis
  • Anemia
  • Electrolyte imbalances
  • Low blood sugar
  • Constipation
  • Bloating and other gastrointestinal issues.
