What is ARFID?

What seems like picky eating could be something much more serious

Lots of kids are picky eaters — it’s like a childhood rite of passage. Kids might refuse to eat something because they don’t like the way it looks or smells, or maybe they have a fear of trying something new.

But sometimes what seems like picky eating could be something much more serious and complex, like avoidant/restrictive food intake disorder (ARFID).

Children with ARFID have an extreme aversion to certain foods or a fear around eating that’s so severe it affects their nutrition, growth and daily functioning. ARFID, sometimes called selective eating disorder, is not picky eating, and it’s more than a temporary phase.

“Kids don’t outgrow ARFID, and without treatment, it can get worse and lead to significant health concerns,” says Dean Focht, MD, a pediatric gastroenterologist at Geisinger. “Recognizing the signs of ARFID, apart from picky eating, is the first step to getting your child the help they need to grow and thrive.”

What is ARFID?

ARFID is a mental health and complex eating disorder where kids continually limit the amount and type of food they eat. Avoidance is so extreme that it can lead to inadequate nutrition, weight loss or failure to meet expected growth.

Unlike other eating disorders, ARFID is not driven by concerns about body image or shape. Instead, many kids with ARFID avoid foods due to sensory sensitivities to texture, taste, color or smell, fear of adverse outcomes like choking or vomiting, or low interest in eating.

“ARFID is not picky eating,” says Dr. Focht. “Picky eating usually only targets a few foods and doesn’t affect your child’s appetite or their normal growth and development pattern. And it’s typically a temporary phase that goes away as a child grows.”

ARFID may coexist with conditions like anxiety, autism spectrum disorder, attention-deficit/hyperactivity disorder or gastrointestinal issues, such as celiac disease or inflammatory bowel disease.

Signs of ARFID

ARFID often involves persistent patterns or common behaviors that interfere with a child’s nutritional needs and daily life.

Common signs of ARFID include:

Sensory-based avoidance. Consistently avoids foods based on texture, smell, taste or appearance.
Fear of outcomes. Fears what might happen after eating, such as choking, vomiting or an allergic reaction — especially if a child had a previous traumatic event at mealtime.
Low appetite. Lacks interest in eating or doesn’t have an appetite, eats unusually slowly.
Extreme pickiness. Meals are limited to a selection of “safe” foods or certain brands.
Rigid rituals around eating. Sets specific rules around eating, such as food has to be separated on their plate, must eat items in a specific order or only eats foods prepared a certain way.
Anxiety or mood changes at mealtime. Feels stress when eating in social settings or fears trying new foods. Anxiety might cause kids to vomit or gag when exposed to certain “unsafe” foods.

“These behaviors can lead to dangerous nutritional deficiencies that cause physical symptoms parents can watch for,” says Dr. Focht. “Kids with ARFID can have unintended weight loss and fail to meet expected weight milestones on growth charts. They also might have extreme fatigue, dizzy spells or frequent stomach aches and constipation problems.”

How ARFID affects a child’s overall health

As kids grow and develop, their bodies require a balanced mix of proteins, fats, carbohydrates, vitamins and minerals to support brain development, muscle building and bone strength.

But when kids restrict their diets so much that they don’t meet their nutritional and energy needs, it can cause health complications that stall growth, delay puberty and affect behavior.

Nutritional deficiencies, like low levels of iron, vitamin D, calcium, zinc and B vitamins, can lead to anemia, weakened bones, dental issues, hair thinning, brittle nails, slow wound healing and frequent infections. Kids also might have dizziness or even faint due to low blood pressure. In severe cases, hospitalization may be required to correct dehydration and malnutrition.

In addition, inadequate nutrition can impair memory, attention and mood, making learning and emotional regulation harder.

“Kids with ARFID might refuse to eat with friends at school or shy away from social situations centered around eating,” says Dr. Focht. “So, they might miss out on birthday parties, camps and family celebrations, which can increase isolation and anxiety.”

When to contact your doctor about ARFID

If your child has persistent avoidance patterns that seem to go beyond picky eating — and last more than a few weeks, worsen or affect daily life — start by talking with your child’s pediatrician. They can assess your child’s symptoms, rule out other medical causes and make referrals, if necessary.

Keeping a food and symptom diary can help with diagnosis and treatment. Take note of which foods are avoided, triggers like textures or smells, physical symptoms and how eating patterns are affecting your child’s behavior.

If an ARFID diagnosis is confirmed, a team of specialists, which can include behavioral health and mental health professionals, dietitians and gastroenterologists, will develop an individualized care plan that might include therapy, medical monitoring and nutrition support.

“ARFID is a complex disorder that doesn’t go away without treatment,” says Dr. Focht. “By spotting symptoms early on and getting the right treatment, we can help your child develop a healthier relationship with food — and regain nutritional health for optimal growth and development.”
