Roles of Food Allergy among AD Patients

Food allergies are one of many triggers for atopic dermatitis (AD), alongside environmental and genetic factors. While not all AD patients have food allergies, the “Big 8” allergens (milk, eggs, soy, wheat, peanuts, tree nuts, fish and shellfish) often worsen symptoms. Diagnosis involves allergy testing, like skin prick tests and serum IgE levels, to identify triggers. Early treatment of AD can help prevent the progression to food allergies by improving the skin barrier and reducing immune sensitization. Effective management includes identifying and avoiding triggers, controlling AD with topical treatments, and, insome cases, immunotherapy for long-term symptom relief.
