The study found that about 35% of cases of moderate to severe eczema, especially in children, were related to food allergies. It should be noted that if the eczema rash persists for several months or years, after treatment with topical steroid creams, moisturizing and anti-allergic drugs, the rash is still repeated, or even worsened, it is cheaper to perform an allergen test early. In addition to urticaria or eczema, there are also food allergies. This is common in school-aged children and adolescents with eczema, or in cases where urticaria is repeatedly uncontrolled, and is ultimately diagnosed as mixed allergies, such as the co-existence of dust mite allergens and food allergens.

‧Also genetic
Allergic diseases often run in families. Similar to allergic diseases such as asthma and allergic rhinitis, food allergies are also hereditary.

‧Oral specific immunotherapy
It should also be noted that although oral specific immunotherapy for food allergy has a certain effect, there are also risks of adverse reactions, including severe allergic reactions. Therefore, food immunotherapy is generally not recommended as a routine clinical treatment because of its safety. And its effectiveness still needs to be confirmed by large-scale and further research.
