3

Environmental allergen control

Reducing exposure to common allergens including dust mites, pet dander, pollen, and mold can help manage elevated IgE-related symptoms and potentially reduce levels over time.

Additional treatment options

IgE level monitoring

Periodic measurement of serum IgE levels helps track trends and response to treatment interventions. Levels may normalize with age or appropriate management.

monitoring

Elimination diet trial

If food allergies are suspected contributing to elevated IgE, guided elimination diets under supervision can identify trigger foods and reduce immune activation.

dietary

Probiotic supplementation

Probiotic supplementation may support gut immune regulation and potentially modulate allergic responses. Evidence is supportive but not conclusive for IgE reduction.
