Why Do I Get Eczema From My Allergies?
Allergies and eczema are related in the sense that they both involve the immune system and can share common underlying factors. Eczema, also known as atopic dermatitis, is a chronic skin condition characterized by red, itchy, and inflamed skin. While allergies don't directly cause eczema, there is a complex interplay between allergic reactions and the development or exacerbation of eczema symptoms.
The skin of individuals with eczema tends to be more sensitive and prone to inflammation. Here's how allergies and eczema are connected:
Immune System Response: Both allergies and eczema involve an abnormal immune system response. In the case of allergies, the immune system reacts to allergens (substances that trigger allergies) by releasing chemicals like histamines, leading to allergic symptoms. In eczema, the immune system response involves inflammation and an overactive response to certain triggers.
Atopic March: There is a phenomenon known as the "atopic march," which describes the typical progression of allergic diseases in some individuals. It often begins with eczema in infancy, followed by allergic rhinitis (hay fever) and asthma later in childhood. This suggests a shared underlying genetic and immunological predisposition.
Common Triggers: Certain allergens that trigger allergic reactions, such as dust mites, pet dander, or certain foods, can also exacerbate eczema symptoms in individuals who are prone to both conditions. Exposure to these allergens can contribute to increased inflammation and itching in the skin.
Skin Barrier Dysfunction: Individuals with eczema often have a compromised skin barrier, making their skin more susceptible to irritants and allergens. This compromised barrier allows allergens to penetrate the skin more easily, triggering immune responses and worsening eczema symptoms.
It's important to note that not everyone with eczema has allergies, and not all allergies lead to eczema. However, for those who experience both conditions, managing allergies through allergen avoidance and other measures may help alleviate eczema symptoms. If you suspect that allergies are contributing to eczema, consulting with a healthcare professional, such as an allergist or dermatologist, can help determine the appropriate course of action for managing both conditions.
