### What Causes and Triggers Eczema? Doctors aren't entirely sure what causes eczema, but the most common type, atopic dermatitis, seems to resemble an allergy. However, it's not an allergic reaction. Eczema is likely caused by a combination of factors, including genetics and environmental triggers. #### Causes: - **Genetics:** If your family has a history of eczema, asthma, or hay fever, you might be more likely to develop it. - **Immune System:** An overactive immune system can cause your skin to overreact to minor irritants or allergens. - **Environment:** Cold weather, dry climates, and pollution can contribute to eczema. #### Triggers: - **Skin Irritants:** Substances like wool, synthetic fabrics, soaps, and detergents can irritate the skin and trigger a flare-up. - **Allergens:** Pollen, pet dander, and dust mites can also trigger eczema in some people. - **Stress:** Emotional stress can worsen eczema symptoms. - **Weather:** Extreme temperatures and humidity levels can dry out the skin and trigger eczema. Eczema is not contagious, so you can't catch it from someone else. While it's not an allergic reaction, many children with eczema also have food allergies. Common food allergens include dairy, eggs, and nuts. However, removing these foods from your child's diet should only be done after consulting a doctor to ensure their nutritional needs are met. Understanding these causes and triggers can help manage and reduce eczema flare-ups, especially in children who are more commonly affected by this condition.
