Skin rashes, such as eczema (also known as atopic dermatitis), and food allergies often show up together. Both are caused by the immune system reacting to things around us. But why do these conditions often happen at the same time, and how are they linked?
What’s the Connection?
Eczema and food allergies are part of something called the "Atopic March." This is the way some conditions develop, starting with eczema in babies and sometimes leading to food allergies, hay fever, and asthma as they grow up. If you’re not familiar with the Atopic March, you can learn more in our article on The Atopic March: Understanding the Progression of Atopic Disorders.
Usually, eczema comes first. While eczema doesn’t directly cause food allergies, having eczema can make the skin weaker and more likely to let in allergens (like food proteins). This can cause the immune system to react and develop food allergies. This idea is called the "Dual Allergen Exposure Hypothesis." It suggests that when the skin is broken, early exposure to allergens can lead to allergies, but eating those same allergens might help the immune system learn not to overreact.
What Are the Symptoms of Skin Rashes Like Eczema and Food Allergies?
Skin rashes like eczema and food allergies have different symptoms, but sometimes they overlap. Eczema usually causes dry, itchy, and red skin. It often shows up on the face, hands, feet, inside the elbows, and behind the knees. Food allergies, on the other hand, can cause hives, vomiting, diarrhea, coughing, and even serious reactions like anaphylaxis.

Some parents notice that certain foods make their child’s eczema worse. If you see this happening, it’s a good idea to talk to a doctor or allergist.
How to Manage Food Allergies and Eczema
To manage both eczema and food allergies, the first step is to figure out and avoid triggers. For eczema, this might mean using gentle, fragrance-free skincare products and avoiding certain fabrics. For food allergies, you’ll need to avoid the foods that cause reactions. You can learn more about managing eczema in our article What is Atopic Dermatitis?
Even though eczema and food allergies are linked, they are still separate conditions. As scientists continue to study their relationship, understanding how they’re connected can help you manage them better. Remember, being informed and working with your doctor is key to keeping your child healthy and happy!
