ARFID: Signs, Causes and Treatment Options

01Definition

What ARFID is

NHS inform explains that someone with ARFID might avoid eating certain foods or types of food, or restrict how much they eat, to the point that it affects their physical and mental health. It may cause underweight, nutritional deficiencies, reliance on nutritional supplements or tube feeding, a significant impact on daily life and effects on mental health.

NIMH describes ARFID as limiting the amount and variety of food because of anxiety or fear about the consequences of eating, such as choking or vomiting, or dislike of a food’s characteristics, such as its appearance or texture. NIMH stresses that eating disorders are not a choice.

02Differences

How it differs from picky eating and from anorexia

NHS inform states that ARFID is more than being a picky eater: the restriction is severe enough to harm health. NIMH describes a limited range of preferred foods that becomes even more limited over time, “picky eating” that gets progressively worse.

ARFID is also different from anorexia nervosa. NHS inform explains that ARFID is not driven by worries about body shape or weight. A person may lose weight, but the reason for avoiding food is sensory, fear-related or low interest, not a wish to change their body.

03Patterns

Main patterns: sensory, fear, low interest

NHS inform describes three common reasons, which can occur together, and notes that sometimes there is no clear reason:

• Sensory-based avoidance: sensitivity to the taste, texture, smell or appearance of certain foods, or eating foods only at a certain temperature.
• Concerns about the consequences of eating: after a distressing experience, fear of vomiting or choking causes anxiety around food.
• Low interest in eating: difficulty recognising hunger, a generally poor appetite or seeing eating as a chore.

Possible signs include always having the same meals, eating only foods of a similar colour, eating something different from everyone else, avoiding social situations with food, feeling full after a few mouthfuls, taking a long time to eat and anxiety at mealtimes.

04Who

Who it affects: any age, any weight

NHS inform explains that anyone can have ARFID, at any age and any weight. Although some people lose weight or have low weight, this is not always the case. In young people, it can affect growth or expected weight gain.

ARFID can occur on its own or alongside other conditions. NHS inform lists anxiety disorders, autism, ADHD and physical health problems such as gastrointestinal conditions as the most common. Having one of these conditions does not mean a person has ARFID. See our guide to generalised anxiety disorder.

05Effects

Health and social effects

NHS inform warns that ARFID can lead to severe and sometimes permanent complications, including poor circulation, heart problems such as irregular heartbeat, and health problems caused by a lack of vitamins and minerals, such as iron-deficiency anaemia. An imbalance of minerals in the blood, such as potassium, calcium and sodium, can cause tiredness, weakness, dehydration, seizures, irregular heartbeat, muscle spasms and confusion.

NIMH adds unhealthy weight loss, malnutrition, changes to physical growth and functional problems with study, work and relationships. Stomach pain or other digestive problems with no other known cause can also be a sign.

06Diagnosis

How it is diagnosed

NHS inform explains that your GP will ask about your eating habits and may check your weight and other physical measurements. Answer honestly: the aim is not to judge you but to understand your symptoms.

NIMH advises talking to a primary care provider if you are concerned about your eating or mental health; they can refer you to a qualified mental health professional, such as a psychologist or psychiatrist. Other medical causes of digestive symptoms or weight loss may also need to be checked.

07Treatment

Treatment: therapy and nutrition support

NHS inform explains that treatment depends on symptoms, situation and age. For adults, it may be provided by specialist eating disorder services, general mental health services or other professionals, and often includes family-based therapy, cognitive behavioural therapy, behavioural interventions such as exposure work and anxiety management training. It may also include nutritional management with a dietitian and help with sensory problems.

NIMH describes eating disorder treatment as a plan that may combine psychotherapy, medical care and monitoring, and nutritional counselling. It notes that there are currently no medicines approved by the US Food and Drug Administration to treat ARFID; medicines may be used for co-occurring anxiety or depression. Children and young people are treated through child and adolescent health services.

08Exposure

Gradual exposure, never forced

NHS inform lists exposure work among the behavioural interventions used to treat ARFID. It is delivered by professionals as part of an individual treatment plan, alongside therapy, anxiety management and dietitian support, not something to impose at home.

The sources do not suggest pressuring someone to eat new foods or setting calorie targets on your own. Agree any changes with the treating team.

09Sources

Where the sources differ

NIMH (revised 2024) states that people with ARFID are frequently underweight and lists dramatic weight loss among the signs. NHS inform (July 2026) stresses that ARFID can happen at any weight and that weight loss is not always present. Both are compatible: weight loss is common but not required, so normal weight does not rule out ARFID. NIMH also notes that family-based treatment can improve outcomes, particularly for adolescents.

If you are worried about a family member, NHS inform advises talking to them, offering support and encouraging them to see their GP. For adults, our psychology practice in Bilbao can assess anxiety around food, with support from our nutrition service (consultations are in Spanish).

10Summary

In summary

ARFID is an eating disorder in which a person avoids foods or eats too little because of sensory sensitivity, fear of consequences such as choking, or low interest in eating, not because of body image. It can affect anyone at any age and weight and can cause serious physical and social problems. Treatment is individual and may include psychological therapy, gradual exposure, anxiety management and dietitian support.

A first-appointment sheet can help. Write down the foods you accept, how they need to be prepared, situations you avoid such as eating out, how your eating affects your energy, weight, work, studies and social life, and any digestive symptoms. There is no need to count calories: describing your experience is what matters.
