I have eczema. Can foods like dairy or peanuts worsen it?

Question

Hello doctor,

I am 26 and have chronic eczema mainly on my hands and behind my knees. It flares up during periods of stress or a sudden change in weather.

My IgE was 420 IU/mL, and the patch test did not show a strong allergen. I use steroid cream occasionally, but it causes my skin to thin. So my concerns are -

Are there safer long-term creams, such as Tacrolimus or Pimecrolimus, that can be used daily?
Additionally, would Dupilumab injections be beneficial if topical options do not adequately control itching?
Can food triggers like dairy or peanuts worsen the condition even without a true allergy?
Lastly, is it okay to use mild fragrance-free moisturizers multiple times a day to prevent dryness?

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

I would like you to know that eczema is a chronic inflammatory condition caused by changes in the immune system and is generally triggered by various factors. These triggers can flare up the lesions, as in your case.

Common triggers include an improper sleep schedule, stress, an unhealthy sedentary lifestyle, alcohol, lack of exercise, or hormonal imbalance. You need to identify and correct your specific triggers.

Yes, long-term use of topical steroids can cause skin darkening, thinning, and pigmentation. They usually provide only temporary relief.

Biologics are now available and are widely used for eczema, especially in moderate to severe cases. These are antibody-based medications designed to specifically target eczema lesions.

They are more effective than steroid injectables and do not suppress the immune system, making them well-tolerated.

You can consider Dupilumab, which is particularly effective for people whose condition is not well controlled with topical treatments.

It is given as a subcutaneous injection. However, before starting any treatment, always consult your primary treating physician.

You can use mild moisturizers, and petroleum jelly is also suitable. Atopic dermatitis is the most common type of eczema and can be triggered by certain foods, such as soy, peanuts, and some dairy products.

I hope this helps.

Thank you and take care.

Regards.
