What are the best treatments for Avoidant / Restrictive Food Intake Disorder (ARFID)?

Avoidant / Restrictive Food Intake Disorder (ARFID) is primarily treated through a multidisciplinary approach combining specialized psychotherapy, nutritional rehabilitation, and occasionally medication to address co-occurring anxiety or sensory sensitivities. Treatment for Avoidant / Restrictive Food Intake Disorder (ARFID) is highly individualized, focusing on gradual exposure to feared or avoided foods while ensuring medical and nutritional stability.

What are the first-line treatments for ARFID?

The current gold standard for Avoidant / Restrictive Food Intake Disorder (ARFID) is Family-Based Treatment (FBT) or Cognitive Behavioral Therapy for ARFID (CBT-AR). These therapies focus on identifying the specific drivers of food avoidance—whether sensory sensitivity, fear of aversive consequences (like choking), or lack of interest in eating—and systematically expanding the patient's diet under the guidance of a therapist.

Which professionals should be on an ARFID care team?

Because Avoidant / Restrictive Food Intake Disorder (ARFID) affects both physical health and psychological well-being, an integrated team is essential. A comprehensive care team typically includes:

• A registered dietitian (specializing in eating disorders) to track nutritional intake.


• A pediatrician or primary care physician to monitor growth, electrolytes, and physical health.


• A psychologist or psychiatrist to manage cognitive behavioral interventions.


• An occupational therapist to assist with sensory integration issues.

Are there medications to treat ARFID?

There is no FDA-approved medication specifically for Avoidant / Restrictive Food Intake Disorder (ARFID). However, clinicians may prescribe medications to manage co-occurring conditions that exacerbate feeding difficulties, such as anxiety or depression. Common options include:

• Selective serotonin reuptake inhibitors (SSRIs) like fluoxetine (Prozac) or sertraline (Zoloft) for anxiety.


• Mirtazapine (Remeron), sometimes used for its potential side effects of appetite stimulation and reduced nausea.

How does treatment effectiveness vary?

Effectiveness varies significantly based on the subtype of Avoidant / Restrictive Food Intake Disorder (ARFID). Patients with sensory-based avoidance may see faster progress with occupational therapy, while those with fear-based avoidance often require more intensive cognitive behavioral exposure. Our community at DiseaseMaps.org, which includes 25 members living with Avoidant / Restrictive Food Intake Disorder (ARFID), highlights that recovery is rarely linear and requires ongoing patience.
