From the Research
For treating nausea associated with Avoidant/Restrictive Food Intake Disorder (ARFID), a multi-faceted approach is recommended, prioritizing the most recent and highest quality study available 1. When considering treatment options, it's essential to address both the physical symptoms of nausea and the psychological anxiety around eating.
Key Considerations
- Start with antiemetic medications such as ondansetron (Zofran) 4-8mg taken 30 minutes before meals, or promethazine 12.5-25mg as needed, as these have been shown to be effective in managing nausea 2.
- For longer-term management, consider low-dose antidepressants like mirtazapine 7.5-15mg at bedtime, which can reduce nausea while stimulating appetite.
- Behavioral strategies are equally important: eat smaller, more frequent meals; avoid triggering foods; practice relaxation techniques before eating; and use gradual exposure to feared foods.
- Ginger supplements (250-500mg) or peppermint tea may provide natural relief.
Multidisciplinary Approach
ARFID treatment works best with a multidisciplinary approach combining medication management with cognitive-behavioral therapy specifically targeting food avoidance, as highlighted in the study of adult patients with ARFID 1. The underlying mechanism involves addressing both the physical symptoms of nausea and the psychological anxiety around eating, as these often create a self-reinforcing cycle where fear of nausea leads to restricted eating, which can worsen gastrointestinal symptoms through irregular eating patterns.
Clinical Presentation
Understanding the clinical presentation of ARFID is crucial, including the identification of subtypes such as low appetite, sensory sensitivity, and fear of adverse consequences, as described in the assessment of patients with ARFID 3. By acknowledging the complexity of ARFID and its various presentations, healthcare providers can tailor treatment approaches to meet the unique needs of each patient, ultimately improving outcomes in terms of morbidity, mortality, and quality of life.
