What causes eczema?

Eczema is a stubborn allergic skin disease, which is caused by many factors.

What are the factors that cause baby eczema?

Infantile eczema is the manifestation of atopic dermatitis in infancy. Idiopathic dermatitis is also called atopic dermatitis, atopic eczema, hereditary allergic dermatitis and hereditary allergic eczema. It is related to hereditary allergy.

If the parents have allergic diseases such as asthma, urticaria and allergic rhinitis, the child has immune abnormalities. The content of IgE in plasma of children with eczema is several times to several times higher than that of normal infants, which is determined by genetic factors. Some babies may have other allergic diseases such as bronchial asthma or allergic rhinitis during or after the onset of eczema, which is closely related to hereditary allergic constitution.

2. Environmental factors.

(1) Indoor temperature and humidity have certain influence on the incidence of infantile eczema. In order to prevent the baby from catching cold, many mothers rarely open the window for ventilation, which leads to indoor humidity or overheating; Some people live in places that are too wet or too dry, which will also aggravate eczema. In hot summer and other seasons, the indoor temperature is too high, bathing with hot water, wearing too many clothes and not paying attention to hygiene may aggravate the child's condition.

(2) Some mothers dry or dry their baby's diapers and other clothes at home, which leads to the occurrence or aggravation of baby eczema.

Among the mothers of children with eczema, 92.7% once paid great attention to nutrition during pregnancy, mainly eating high-protein diets such as chicken, duck, fish and shrimp, and some like to eat spicy and irritating food.

In addition, some wet nurses give priority to eggs, beef and mutton in order to strengthen nutrition. Breastfeeding mothers eat spicy and other stimulating foods and seafood products, which may also aggravate their children's eczema.

Therefore, if a mother finds her baby allergic during pregnancy or lactation, she can consider whether she is allergic to protein and induce eczema.

4. Improper medication and nursing.

Infantile eczema is called "milk tinea" in Chinese medicine. Some parents use drugs to treat infantile eczema, which makes the condition worse.

The erosion and exudation of baby's skin lesions are obvious, and some parents of children use irritating Chinese medicine to scrub the skin lesions; Children's skin lesions are dry, and parents over-clean the skin lesions or burn them with hot water or rinse them with salt water, which aggravates the symptoms. Some children have severe itching, which affects sleep, and some have secondary infection. Parents also insist on not giving drugs to their children, which leads to aggravated symptoms.

5. Psychological factors.

Because of the fear of eczema recurrence or aggravation, parents often worry that their baby may be allergic to certain substances, prone to cleanliness, too simple diet, and limit its range of activities. It makes children prone to malnutrition or imbalance of immune function, reduces their adaptability to the external environment, and makes baby eczema more stubborn and refractory.

Parents' adaptation to this environment, due to genetic and other factors, the baby also adapts to this environment.
