What causes urticaria in babies?

Urticaria is a very common skin disease and also a common disease in infants. It is what we often call urticaria. When the symptoms appear, red wheals of varying sizes can be seen on the baby's skin, and they feel hard to the touch. The characteristics of rubella are that it occurs quickly and disappears quickly, but it is easy to recur. Next, let’s take a look at the specific causes of urticaria.

1. Internal factors.

(1) The baby has a hereditary allergic constitution, or his or her vascular, neurological and immune functions are impaired. If allergens such as pollen, mold, and animal dander are eaten or inhaled, they can easily pass through the thin intestinal wall and enter the blood. Because babies have abundant subcutaneous capillaries, the symptoms will appear immediately on the skin.

(2) Imperfect gastrointestinal system and weak immunity.

2. External factors.

The most common external factors that cause baby urticaria are drugs and food:

(1) Food: nuts, seafood, eggs, strawberries, mushrooms, milk, etc.

(2) Drugs: penicillin, streptomycin, sulfonamides, aspirin, chloramphenicol, furazolidone, serum, vaccines, etc.

(3) Inhalants: pollen, dust, smoke, etc.

(4) Sources of infection: bacteria, viruses, fungi, parasites, etc.

(5) Animal and plant irritants: bed bugs, mites, nettles, kudzu, etc.

(6) Physical factors: excessive cold, excessive heat, cold wind, sunlight and stimulation from certain skin care products, etc.

3. Depending on the age of the baby, the causes of urticaria may vary.

(1) Breastfeeding period: If the infant is mainly fed with breast milk, milk, and dairy products, the causes of urticaria are often related to the additives in milk and dairy products.

(2) After adding complementary foods: As they grow older, infants and young children begin to add complementary foods. At this time, eggs, meat floss, fish floss, fruit juice, vegetables and fruits can all become causes of allergies.
