Crossing Paths: The Intersection of ARFID, Autism, ADHD, and Anxiety
Some people have Avoidant/Restrictive Food Intake Disorder (ARFID). Some have autism. Some have both. Some have ADHD with or without ARFID or autism. Others experience anxiety without any of these diagnoses.
And there are individuals who have never struggled significantly with food who experience a traumatic or negative event involving food—such as choking, vomiting, or another frightening experience—and subsequently begin avoiding foods, lose weight, or experience significant changes in their eating.
These individuals may or may not have a history of anxiety or another diagnosis. Their eating concerns may be entirely new.
Having an accurate diagnosis matters.
A diagnosis can help treatment providers understand what is happening, develop an appropriate treatment plan, validate an individual's experience, and identify the accommodations and supports that may be needed at school, work, or home.
ARFID, Autism, ADHD, and Anxiety Can Overlap
Let's think specifically about ARFID.
ARFID is an eating disorder characterized by avoidance or restriction of food that is not driven by concerns about body weight or shape. People with ARFID may experience food avoidance for one or more reasons, including:
Fear of aversive consequences, such as choking, gagging, vomiting, or experiencing another negative consequence from eating
Lack of interest in eating or food, including limited hunger cues or difficulty recognizing the need to eat
Sensory sensitivity, such as difficulty with the taste, texture, smell, temperature, appearance, or other sensory characteristics of food
These experiences can overlap with symptoms commonly seen in autism, ADHD, and anxiety. However, having one of these diagnoses does not automatically mean someone has ARFID.
Likewise, being a picky eater or having sensory sensitivities does not automatically mean someone has ARFID.
For an individual to meet diagnostic criteria for ARFID, the restriction or avoidance must also result in significant consequences. These can include:
Significant weight loss or, in children, failure to achieve expected weight gain or faltering growth
Significant nutritional deficiency
Dependence on enteral feeding or oral nutritional supplements
Marked interference with psychosocial functioning, such as significant difficulty participating in social meals, school, work, or other daily activities
Can You Have ARFID at a Higher Weight?
Yes.
ARFID can sometimes be overlooked in individuals who are at an average or above-average weight because weight alone does not tell us whether someone is adequately nourished or whether their eating disorder is significantly affecting their life.
When evaluating someone for ARFID, providers need to look beyond weight and consider the individual's nutritional adequacy, food variety, reliance on supplements, growth history when applicable, and psychosocial functioning.
Someone can have significant nutritional deficiencies or substantial interference with daily life even when their weight does not appear concerning.
The Diagnosis Is Important—But Symptoms Drive Treatment
While diagnosis is an important part of the treatment process, the diagnosis name itself is not what determines every part of an ARFID treatment plan. The individual's specific symptoms and the factors maintaining food avoidance are what guide treatment.
For example, someone with ARFID may have significant sensory sensitivities, while another person with ARFID may have very few sensory concerns.
Someone with autism may have sensory sensitivities, but not everyone with autism does.
Someone with ADHD, OCD, or anxiety may experience sensory sensitivities, but those symptoms can look very different from person to person.
As ARFID treatment professionals, we need to identify which symptoms are actually affecting eating and address those specific concerns.
ARFID, Anxiety, and Fear of Food
Individuals with ARFID and anxiety may experience significant anxiety around new foods, eating, or food-related situations.
For some people, food-related anxiety is part of a broader pattern of anxiety around new or uncertain experiences. For others, the anxiety may be specifically connected to a fear of choking, vomiting, gagging, illness, or another negative consequence.
In ARFID treatment, this may involve:
Identifying the fears surrounding food
Identifying thoughts that contribute to those fears
Learning anxiety-management and coping skills
Learning to regulate the nervous system
Challenging unhelpful thoughts and predictions
Gradually approaching feared foods and eating situations rather than continually avoiding them
The goal isn't simply to tell someone to “try the food anyway.”
Treatment needs to address the factors that are making the food feel unsafe or overwhelming in the first place.
ARFID, Autism, ADHD, and Lack of Interest in Food
Some individuals with ARFID, autism, or ADHD may experience low interest in food or difficulty initiating eating.
They may not naturally think about food, recognize hunger cues, seek out food, or respond strongly when food is offered.
For someone with ARFID, treatment may involve developing practical strategies to support regular eating even when hunger isn't providing a strong reminder to eat.
This might include:
Establishing consistent meal and snack times
Creating reminders or routines
Making food more accessible
Identifying reliable foods that can support adequate nutrition
Gradually increasing food variety when appropriate
Developing strategies for eating in different environments
Again, the treatment needs to address the specific reason food is being avoided or restricted.
What About Picky Eating?
This distinction is especially important because picky eating and ARFID are not the same thing.
Many children—and adults—have food preferences, avoid certain foods, or go through periods of selective eating without meeting criteria for ARFID.
At the same time, what looks like “picky eating” can sometimes be a sign of a more significant feeding or eating concern.
Rather than focusing only on how many foods someone eats, we need to ask:
Why are they avoiding these foods?
How significant is the restriction?
Is their nutritional status being affected?
Is their growth or weight being affected?
Are they relying on supplements to meet their nutritional needs?
Is eating interfering with school, work, social activities, family meals, or other areas of life?
The answers to these questions can help determine whether someone is experiencing typical picky eating, ARFID, another feeding or eating concern, or symptoms related to another condition.
Why the Correct Diagnosis Matters
It can be tempting to look at a person's eating and immediately assume we know what is causing it.
An autistic person may have food selectivity—but may not have ARFID.
A person with ADHD may have difficulty remembering to eat—but may not have ARFID.
A person with anxiety may avoid certain foods because of fear—but may not have ARFID.
A person who has experienced a traumatic food-related event may suddenly develop significant food avoidance without having a previous history of eating difficulties.
And someone can have more than one diagnosis at the same time.
This is why a thorough evaluation is so important.
The goal isn't simply to find a label. The goal is to understand what is happening well enough to provide the right treatment.
What Should You Do If You Suspect ARFID?
If you are concerned that you or your child may have ARFID, seek an evaluation from a qualified healthcare professional who understands ARFID and eating disorders.
Treatment may involve a multidisciplinary team, depending on the individual's needs. This can include a physician, registered dietitian, therapist, occupational therapist, speech-language pathologist, and other professionals.
The team may need to address nutrition, food exposure, anxiety, sensory processing, fear of aversive consequences, eating routines, medical concerns, and other factors contributing to food avoidance.
The most important takeaways:
1. Seek a qualified provider for an evaluation and accurate diagnosis.
2. Don't assume autism, ADHD, anxiety, sensory sensitivity, or picky eating automatically means someone has ARFID.
3. Don't assume someone doesn't have ARFID simply because they are at an average or above-average weight.
4. Once ARFID is identified, treatment should target the specific symptoms and factors contributing to food avoidance.
5. A multidisciplinary approach may be beneficial when multiple areas are affecting eating and recovery.
Understanding why someone is struggling to eat is just as important as understanding what they are eating.
The right diagnosis can help us ask better questions, develop more effective treatment plans, and provide individuals and families with the support they actually need.
