There are many reasons for eczema, such as inheritance, environment, infection will affect, and diet will be closely related to eczema.
I. Genetic factors
Eczema in infants is closely related to genetic factors, especially in direct relatives with eczema or other allergic symptoms, eczema in infants is the most common.
The impact of environmental factors mainly refers to the increasing and complex environmental allergens, including:
1. Clothing: Environmental allergens of modern clothing, such as artificial fabrics, artificial leather products, dye bleaching agents, moth-proof agents, mildew-proof agents and stiffeners related to clothing.
2. Food: Chemical fertilizers, pesticides, artificial feeds, feed additives for food production, preservatives, mineral oxidants, spices, pigments, ripening agents, thickeners for food processing, modern dietary environmental allergens.
3. Residence: Functions of Artificial Building Components, Chemical Coatings, Plastic Products, Rubber Products, Artificial Fibers, Adhesives, Waterproofing Agents, Electromagnetic Radiation from Household and Office Electronic Equipment, Residential Cleaner, Insecticide, Environmental Allergens in Modern Residence.
4. Pets: All kinds of fur animals and aquatic animals are also the inducing factors of baby eczema.
Environmental factors are one of the important reasons for the increase of eczema prevalence. Environment includes group environment and individual environment. Human group environment pathogenic factors refer to outdoor large-scale air, water, soil, radiation sources, large-scale sensitized pollen vegetation, large-scale air-borne sensitized bacteria sources and so on. Individual small environment refers to the living environment of an individual. Since about 2/3 of people’s life time is indoor, the impact of individual small environment on eczema is more closely.
Some eczema is related to microbial infection. These microorganisms include Staphylococcus aureus, gas-borne fungi such as Alternaria alternata, Cladosporium, Penicillium spp., Aspergillus fumigatus, Fusarium, Penicillium flavum, Aspergillus Niger and Rhizopus niger. Therefore, some severe eczema treatment will use topical anti-infective drugs.
4. Dietary factors
The most important factor for infants and young children is diet. Because infant food is single, mainly dairy products, so the most important thing for babies is protein allergy. Some babies have eczema after adding supplementary food, which may be related to supplementary food, mainly eggs and some nuts, such as beans, peanuts, sesame and so on.
