Avoidant/Restrictive Food Intake Disorder (ARFID) is a
condition that limits food intake. It does not stem from a negative body
perception or a desire to alter body weight. Fear and anxiety regarding food or
the outcomes of eating, such as choking, can lead to ARFID. Cognitive
Behavioral Therapy (CBT) serves as the primary treatment.
What Is Avoidant/Restrictive Food Intake Disorder
(ARFID)? Avoidant/restrictive food intake disorder (ARFID) causes an
individual to limit the amount and types of food they consume. Unlike other
eating disorders, it is not the result of a distorted body image or an attempt
to lose body weight.
ARFID can lead to:
- Loss
of interest in eating.
- Anxiety
about the consequences of eating, such as choking or vomiting.
- Avoidance
of foods with unwanted colors, tastes, textures, or smells.
A doctor may refer to ARFID as "selective eating
disorder" because an individual might only choose a small selection of
foods deemed acceptable to eat. Additionally, the person may establish specific
eating rituals or behavioral patterns, such as consuming foods in a strict
sequence.
ARFID directly impacts nutrient intake, which can impair
overall health. Left untreated, it may lead to life-threatening complications.
Is ARFID the Same as Picky Eating? ARFID is not the
same as picky eating. Children may avoid certain foods simply because they
dislike the appearance, taste, smell, or texture. Picky eating usually targets
only a few items and does not affect the child's appetite, growth, or
development. It also tends to resolve naturally as the child grows up.
Conversely, ARFID can trigger complications that affect appetite and general
health due to insufficient nutrition. This condition will not resolve without
professional treatment.
How Common Is ARFID? Avoidant/restrictive food intake
disorder (ARFID) is a relatively new diagnosis introduced in the Diagnostic and
Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Consequently,
there is currently insufficient data to accurately estimate how broadly it
impacts the general population.
Symptoms and Signs of ARFID Physical symptoms and
signs of ARFID include:
- Significant
weight loss.
- Constipation.
- Abdominal
pain, stomach cramps, or discomfort.
- Low
body temperature.
- Lethargy.
- Irregular
menstrual cycles.
- Fainting
or dizziness.
- Fine
hair growth on the body (lanugo).
- Muscle
weakness.
Behavioral changes that may indicate ARFID include:
- Feeling
full or lacking appetite before meals.
- Difficulty
maintaining focus.
- Restricting
the quantity of food consumed.
- Eating
only foods with specific textures.
- Fear
of post-eating outcomes, such as vomiting or choking.
- Worsening
pickiness that restricts the variety of acceptable foods.
ARFID is not linked to a negative body image or a desire to
lose weight.
Causes of ARFID The precise cause of
avoidant/restrictive food intake disorder remains unknown. Research suggests it
may result from:
- Anxiety.
- Fear.
- Genetic
variations.
- Social,
cultural, and environmental influences.
- Trauma.
Risk Factors for ARFID ARFID can affect anyone,
including adults and children, though it occurs most frequently during
childhood.
The risk of developing ARFID may be higher in cases
involving:
- Traumatic
experiences, especially involving food (food insecurity, forced feeding,
choking, etc.).
- Underlying
conditions affecting neurological function or development (anxiety,
depression, ADHD).
- Aversion
or avoidance toward specific textures.
- Fear
that food will harm the body.
- A
family history of eating disorders.
Complications of ARFID Complications caused by ARFID
include:
- Malnutrition.
- Dehydration.
- Electrolyte
imbalance.
- Anemia.
- Low
blood pressure.
- Osteoporosis.
- Cardiac
arrest.
- Delayed
puberty.
- Alterations
in physical growth.
The consequences of ARFID can be life-threatening.
Occasionally, an individual diagnosed with ARFID may display no visible
symptoms because the body adapts to the stress. Consequently, test results may
remain inconclusive even when the condition is critical.
ARFID also impacts social interactions. An individual may
avoid visiting loved ones or attending events involving food (such as family
dinners or dinner parties). This can strain relationships and interfere with
work or school responsibilities.
How Is ARFID Diagnosed? A healthcare provider
evaluates specific criteria to diagnose ARFID:
- Restricted
food intake leading to significant weight loss and growth delays in
children, inadequate nutrient absorption, dependence on tube feeding or
vitamin supplements, and/or negative impacts on interpersonal
relationships.
- The
restricted food intake is not caused by food insecurity, religious
fasting, or an underlying medical condition or treatment.
- The
restriction does not stem from a negative body image or a desire to lose
weight or alter body shape.
- If
restricted food intake is associated with a medical condition or
treatment, it exceeds the expected level of side effects and causes severe
health complications.
Doctors may perform physical examinations alongside blood or
urine tests to monitor overall health, nutrient levels, and organ function.
How Is ARFID Treated? ARFID treatment focuses on:
- Reaching
and maintaining a healthy body weight.
- Preventing
complications that impact general health.
- Managing
mental health, sensory avoidances, and food-related fears.
Cognitive Behavioral Therapy (CBT) is the primary treatment
for ARFID. It helps individuals to:
- Recognize
problematic thoughts and behaviors affecting health.
- Reduce
fear or anxiety surrounding food.
- Become
more comfortable when facing sensory challenges.
Doctors may prescribe medications to aid mental and physical
recovery and prevent life-threatening complications. These may include
antipsychotics, antidepressants, or appetite stimulants. Potential side effects
should be discussed with a doctor before starting any medication.
In certain cases, doctors provide nutrition via a temporary
feeding tube (enteral nutrition). This flexible tube runs through the nose or
directly into the stomach or small intestine, delivering nutrients directly
into the body without relying on oral intake.
Who Treats ARFID? An ARFID care team may include:
- A
primary care physician.
- A
mental health professional or Cognitive Behavioral Therapist.
- A
gastroenterologist.
- A
speech and language pathologist.
- Specialists
for managing specific complications.
How Long Does It Take to Feel Better? Treating ARFID
takes time. Because every individual is different, there is no set timeline for
recovery. Relief from symptoms typically increases as the body gets used to
receiving necessary nutrients. Ongoing support from a care team throughout life
may be needed to track progress and monitor potential complications.
What to Expect with ARFID? ARFID is a mental health
condition that physically affects the body. While early stages may resemble
picky eating, the consequences of restricting food intake can become severe and
life-threatening if left untreated. Unlike typical picky eating in children,
ARFID requires lifelong medical intervention for recovery. Hospital visits and
admissions are common.
Because the condition is relatively new, there is no single
treatment method that works for everyone. Most individuals show progress
through a combination of medication and Cognitive Behavioral Therapy.
Can ARFID Be Prevented? There is no known way to
prevent avoidant/restrictive food intake disorder.
When to See a Doctor Consult a doctor if:
- Eating
or drinking becomes impossible.
- Anxiety
occurs during meals.
- There
is a total lack of interest in food.
- Significant
weight loss occurs.
- ARFID
symptoms or signs are present.
Recognizing the need for help can be difficult for someone
with a mental health condition. Support from loved ones plays a crucial role in
encouraging them to seek necessary care.
Questions to Ask Your Doctor
- What
is my specific diagnosis?
- Should
I see a mental health therapist?
- Are
there side effects to the prescribed medication?
- How
can adequate nutrition be achieved if eating is not possible?
- Is
a feeding tube necessary?
What Is the Difference Between ARFID and Anorexia?
Both ARFID and anorexia nervosa are mental health conditions involving
restricted food intake. Anorexia occurs when food is restricted due to a
negative body image and a desire to alter body appearance. ARFID involves
restrictive eating behavior that is not driven by body image distortions.
Is ARFID a Form of Autism Spectrum Disorder? ARFID
shares similarities with autism spectrum disorder, but they are distinct
conditions. While individuals with either condition may avoid specific
textures, those with ARFID risk severe complications like malnutrition due to
sensory avoidance.
ARFID is a complex mental health condition that requires
intervention to resolve. Although it may initially look like picky eating,
failing to consume essential nutrients can lead to dangerous complications.
Recovery takes time, sustained support from a healthcare team, and
encouragement from loved ones.
