Eczema and Food Allergy: Are they related?

Eczema and food allergy are related, but this topic can be confusing. Here, we clarify when you should get tested for food allergies.

Eczema, also known as atopic dermatitis, refers to red, itchy, and dry patches of skin. The exact cause is not fully understood. However, we do know that eczema is the result of a dysfunctional skin barrier. Reactions from environmental allergens (such as pollen, dust mite, mold, and animals) can worsen eczema.

A food allergy happens when the body’s immune system overreacts to a food within minutes to a couple of hours. This is caused by antibodies called immunoglobulin E (IgE). Hives, which is an itchy rash that resembles mosquito bites, is one of the most common symptoms of food allergy. However, many other symptoms are possible. These include swelling, nausea, vomiting, stomach pain, wheezing, shortness of breath, cough, dizziness, and fainting. A severe, life-threatening reaction to food called anaphylaxis can also occur. Food allergy can be confusing! Not all reactions to food are a true allergy.

There is a strong association between eczema and the development of food allergy. A meta-analysis study supports a strong relationship between eczema and development of food allergy later in life. About 30% of young children with eczema may develop food allergies later in life.

Eczema can be treated most of time by proper skin care. However, in cases of moderate-to-severe eczema, certain foods may worsen an eczema rash.
