This is a 4-part (a little more technical) series inspired by a review article “Features of childhood atopic dermatitis” by Hugo Van Bever and Genevieve Illanora. The article summarizes 4 players involved in atopic dermatitis, and I’ve tried to understand whatever I could from the article and hopefully digested the information accurately for you to read.
Does Allergy Cause Eczema?
The answer is we don’t know. If you refer to the first part of this series, allergy is hypothesized to be caused by eczema (rather than causing eczema). What has been observed is that the more severe eczema is, the higher the chances of allergies (as shown in table above). Allergies can be to food (which in the article “Features of childhood atopic dermatitis” summarized that it can be from direct eating/drinking, breast milk, placenta, inhaling and even kissing!), to house dust mites, dander and a whole lot of others (I’ve freaked myself out when researching what my baby girl Marcie could be allergic to).
As it turned out, Marcie is not allergic to anything! She had a skin prick test done, something which I always recommend other parents to do because it takes a lot of guess work out. True that skin prick test is not 100% fail-proof, but it’s better than going mad worrying about everything cos if you google, you will most surely find something written or a post by someone that their child is allergic to something.
