What factors cause skin eczema

Eczema is a relatively common skin disease, especially in the summer, when the incidence rate is relatively high. There are many causes of eczema, some of which are genetic, and environmental factors cannot be ignored, such as changes in temperature and humidity, etc. Diet is also an important cause of eczema, especially for patients with allergic constitutions. Many foods can induce eczema if eaten improperly.

1. Eczema caused by genetic factors

Some types of eczema are closely related to genetics and are caused by genetic factors.

2. Eczema caused by environmental factors

Many studies have confirmed that environmental factors are one of the important reasons for the increase in the prevalence of eczema. The environment includes group environment and individual environment. Human group environmental pathogenic factors refer to large-scale outdoor air, water, soil, radiation sources, large areas of allergenic pollen vegetation, large areas of airborne allergenic bacteria sources, etc. Individual microenvironment refers to the individual's living environment. Since people spend about 2/3 of their lives indoors, the individual microenvironment has a closer impact on eczema. The impact of environmental factors mainly refers to the increasingly increasing and complex environmental allergens.

3. Eczema caused by infection

Some eczemas are associated with infection by microorganisms. These microorganisms include Staphylococcus aureus, Malassezia, aerogenic fungi such as Alternaria, Cladosporium, Penicillium, Aspergillus fumigatus, Fusarium, Penicillium chrysogenum, Aspergillus niger and Rhizopus niger.

4. Eczema caused by dietary factors

There are many varieties of human food, which can generally be divided into plants, animals, and minerals. In modern food, some chemically synthesized foods such as saccharin, acetic acid, citric acid, flavors, synthetic dyes, etc. are often used. These foods can cause food allergies, leading to the occurrence of eczema.

5. Eczema caused by other factors

The occurrence of eczema can also be caused by neuropsychiatric factors such as depression, fatigue, anxiety, tension, emotional excitement, insomnia, and climatic and physical factors such as sunlight, ultraviolet rays, cold, humidity, dryness, and friction. In addition, chronic gastrointestinal diseases, chronic alcoholism, intestinal parasites, metabolic disorders, endocrine disorders and other factors are all causes of eczema.
