I have eczema with high IgE. Will changing my diet help me?

Question

Hello, doctor,

I am 24 and have had severe eczema since childhood. My IgE is 1,050 IU/mL, and I often get skin infections. I have tried topical steroids, Tacrolimus, and even Cyclosporine briefly, but nothing keeps it controlled long-term. My dermatologist now recommends Dupilumab. I am nervous about starting a biologic and looking for suggestions on the following:

How safe is it, and do I have to stay on it forever?
Also, will it help with my chronic dry eyes and nasal allergies, too?
I have read that atopic dermatitis is linked to gut health. Should I be making dietary changes or doing allergy elimination diets alongside treatment?

Please suggest.

Hello,

Welcome to icliniq.com.

I understand your concern.

Given your eczema and high IgE (immunoglobulin E) level, along with recurrent infections, this suggests a severe, persistent atopic dermatitis that has not responded well to conventional treatments. Dupilumab is a biologic specifically approved for moderate to severe atopic dermatitis and has shown excellent long-term safety and effectiveness in many patients.

It works by targeting IL-4 and 13 (interleukin), key drivers of type 2 inflammation, and often leads to significant improvements in skin symptoms, reduced infections, and better quality of life. Many people also notice improvement in related conditions like chronic dry eyes, allergic rhinitis, and even asthma if present, since these conditions often share the same inflammatory pathway.

While Dupilumab does not cure eczema, it can help control it well enough that many patients stay on it long term, though some can taper or space out doses under supervision if their condition stabilizes.

As for diet, while gut health and food triggers may influence inflammation in some people, the role of elimination diets is still not well-defined and should only be done under medical guidance, especially since overly restrictive diets can be harmful.

A balanced, anti-inflammatory diet and avoiding obvious triggers like certain foods or allergens may help, but there is no universal “eczema diet.” If you are starting Dupilumab, you can continue to explore supportive strategies like skincare, allergy management, and nutrition alongside it.

I hope this helps.

Thank you.
