The Connection Between Asthma and Eczema: What You Need to Know

Asthma and eczema may seem like unrelated conditions—one affecting the lungs and the other the skin—but they are actually closely linked. Both are inflammatory disorders that stem from an overactive immune system response, often triggered by allergens or environmental factors. Studies have shown that individuals with eczema (atopic dermatitis) are at a higher risk of developing asthma, a phenomenon known as the "atopic march." This progression occurs because both conditions share genetic and immunological traits, leading to heightened sensitivity in the body’s airways and skin.

The connection between asthma and eczema lies in the body's immune response. People with eczema often have a defective skin barrier, allowing allergens and irritants to penetrate more easily, triggering inflammation. This same immune system hypersensitivity can also affect the respiratory system, leading to asthma symptoms such as wheezing, coughing, and shortness of breath. Inflammation caused by eczema can also lead to an increase in immune cells called eosinophils, which are responsible for allergic reactions in both the skin and the lungs. Because of this shared immune dysfunction, individuals with one condition may experience flare-ups of the other, particularly when exposed to allergens like pollen, pet dander, or dust mites.

Managing both asthma and eczema requires a comprehensive approach that focuses on reducing inflammation and avoiding triggers. At Advanced Allergy & Asthma Centers, we provide personalized treatment plans that may include allergy testing, skin care recommendations, inhaler therapies, and biologic medications designed to control inflammation. If you or your child suffers from both conditions, working with an experienced allergist can help prevent flare-ups and improve overall quality of life.
