Avoidant/restrictive food intake disorder (ARFID) is an eating disorder where people have highly selective eating habits. Individuals with ARFID limit their food intake due to negative psychological associations with particular types of food and eating,
ARFID has only recently been classified by the DSM and is not as clearly understood as some other eating disorders. That’s why it’s important to be aware of the characteristics of ARFID, so you can recognize both the physical and behavioral signs and symptoms in either yourself or a loved one.
Adults with ARFID may lose weight as they struggle to eat over a period of time. An insufficient calorie intake can result in an inability to maintain basic body function. (2)
Children and young people with ARFID may fail to gain weight as expected, and their growth may be affected, with a slowing of height increase. (3) Along with developmental delays, young people with ARFID may also have stunted puberty. For example, the signs of sexual maturity don’t appear as they should by age twelve in individuals who are assigned female at birth, or age fourteen in those who are assigned male at birth.
When someone has an inadequate diet because they only eat a narrow range of foods, they may not be getting the essential nutrients needed for development, their general health, and their ability to function on a day-to-day basis. In some people, this may result in nutritional deficiencies (e.g. iron deficiency), which can result in anemia.
In extreme cases, ARFID can lead to malnutrition. Warning signs and symptoms of malnutrition include: (4)
The persistent failure to meet nutritional needs may lead to a dependence on oral supplements or enteral feeding.
Laboratory tests are likely to exhibit the biomarkers associated with nutrient deficiencies or malnutrition. This includes, but is not limited to anemia, low hormone and thyroid levels, low blood potassium levels, low blood cell counts (indicating a weakened immune system), and an abnormal heart rate.
ARFID goes way beyond picky eating. Although many children and adults may go through phases of selective eating, someone with ARFID does not eat enough calories to grow and develop, or, in adults, to maintain weight and basic body function.
You may notice a sudden or severe restriction of food with no explanation, a decreased appetite or lack of interest in food, eating abnormally slowly, and gagging during meal times. As the condition worsens, the small range of ‘liked’ foods decreases, which can lead to significant weight loss and nutritional deficiencies.
Individuals with ARFID may dress in layers of baggy clothes. This hides weight loss and helps them keep warm.
Being limited in what they can eat or a complete lack of interest in food often causes people to experience significant difficulties in social situations. People may struggle at school, work, college, or with friends. They may feel anxious in social situations due to their eating difficulties. (3)
Adults and children may find it difficult to form friendships or establish close relationships, as they fear the inevitable social eating occasions. Traveling away from home may also be difficult, due to concerns that their ‘safe’ foods won’t be available.
Other psychological issues associated with ARFID include low mood, anxiety, irritability, and difficulty concentrating. (1)
In AFRID, there are no compensatory behaviors that are seen with other eating disorders, such as excessive exercise, bingeing, or purging. (1)
Common symptoms of ARFID are non-specific gastrointestinal issues that can result from an insufficient diet and can contribute to a lack of appetite. They include:
People with ARFID can be hypersensitive to the cold. This is because they are often underweight and, therefore, don’t have a layer of body fat to insulate the body or enough muscle mass to help the body produce heat through metabolism.
Additionally, hands and feet may also appear to be cold to the touch with a mottled appearance. (1) This is usually a sign of low blood pressure and the resultant poor circulation to the extremities.
With ARFID, food restriction is motivated by fear of adverse consequences, such as food poisoning or illness, sensory sensitivity, or other food-related phobias, including: (4)
These fears can develop from a traumatic experience with food, like significant abdominal pain, choking, or even embarrassment, causing an individual to develop anxiety around food and eating. Others with ARFID may have more general anxieties about the consequences of eating that they can’t explain and restrict themselves to what they consider to be “safe” foods. (3)
Both adults and children with ARFID often report vague gastrointestinal problems at mealtimes, which have no known cause. These complaints can include feeling sick, an upset stomach, abdominal pain, and already feeling full and are designed to avoid eating. (6)
ARFID is similar to anorexia nervosa in that there is a severe restriction of food intake. However, people with ARFID differ in that they don’t have anxiety or an obsession over their body weight or appearance, or fear of gaining weight. (7)
ARFID can look different in different people. But however it presents, it can have a negative impact on physical and psychological health. If you recognize a combination of the signs and symptoms above in yourself or in a loved one, and there are issues with restricting food that are not improving, it’s time to get help.
If you think you have ARFID, make an appointment with a medical professional who has experience in eating disorders.who will be able to guide you toward the right treatment. If you’re concerned about a loved one, encourage them to seek help.
Treatment options can include family therapy, cognitive behavior therapy, dialectical behavior therapy, nutrition counseling, and behavioral interventions like exposure work. (3)
