Causes of urticaria in children

Although there are many types of diet nowadays, they are not safe and various diseases follow. For example, patients with urticaria often fall into misunderstandings and take on more health risks and side effects because they do not know how to treat it correctly. Although urticaria itself is not contagious, the allergic constitution of urticaria will be passed on to the next generation: many parents have allergic constitutions, and their children are inherited after birth, causing them to suffer from urticaria. So what are the causes of urticaria in children?

What causes urticaria in children?

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.

The cause of hives may vary depending on your baby's age.

(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.

(3) Preschool and school-age children : Children at this age tend to like to eat snacks, and there are more types of snacks and regular meals, so the chance of food allergies increases. Foods such as nuts, fish, crabs, shrimps, peanuts, eggs, strawberries, apples, plums, citrus fruits, various cold drinks, beverages, chocolate, etc. may become the cause of allergies.

(4) Children aged 2-7 years old lack self-control. When they go outdoors, in the wild, in the bushes, or under street lights in the evening, they are often bitten by insects or come into contact with pollen, dust, mites, and the fur of pets such as cats and dogs, all of which can easily become the cause of allergies.

(5) Children in childhood and early childhood have low immunity and are prone to various infections. Therefore, diseases such as purulent tonsillitis, pharyngitis, enteritis, and upper respiratory tract infections can be triggers of urticaria at any time of the year.

(6) Older children and adolescents are more likely to be allergic to drugs, especially penicillin, which may cause urticaria.

Symptoms of urticaria in children

About 15%-20% of babies have experienced urticaria, which is a very common skin symptom. The child's skin surface is swollen and red spots appear. The baby will feel itchy and keep scratching with his little hands. The rash usually lasts for a few minutes to a few hours before disappearing, but it can sometimes last for a few days.
