What causes urticaria in children due to skin allergies?

Children's skin is very delicate and sensitive. If urticaria occurs due to skin allergies, it is important to understand the cause of the disease and cut off the allergens in order to effectively control the disease. Inaccurate treatment of urticaria can also lead to recurrent urticaria. Remember that urticaria is a very common skin disease, and children's skin allergies lead to urticaria. The first thing we need to do is to find the cause of urticaria.

1. Causes of urticaria in children :

1. Inhalants : such as pollen, dust, animal dander, smoke, feathers, fungal spores, volatile chemicals (such as formaldehyde, acrolein, pyrethrum, cosmetics, etc.) and other airborne allergens.

2. Food : Fish, shrimp, eggs and milk are the most common, followed by meat and certain plant foods, such as strawberries, cocoa and tomatoes. In addition, spoiled food decomposes into polypeptides, and alkaline polypeptides are histamine releasers. Protein foods are absorbed in the form of peptones or polypeptides before being completely digested, which can cause urticaria. This is more common in children and may also be due to the different permeability of the digestive tract mucosa in children and adults. In addition, coloring, flavoring, preservatives, and natural or synthetic substances added to food can also cause urticaria.

3. Drugs : They can be divided into two categories. One is drugs that can form antigens, such as penicillin, serum, vaccines, sulfonamides, furazolidone, etc.; the other is histamine releasers, such as aspirin, morphine, codeine, pethidine, polymyxin, vitamin B, quinine, hydralazine, etc.

4. Genetic factors : Some types of urticaria are related to genetics, such as familial cold urticaria, hereditary familial urticaria syndrome, etc.

2. Children suffering from urticaria should pay attention to :

1. Avoid scratching : Once people suffer from urticaria, they should avoid letting children scratch the affected area with their hands, otherwise the more they scratch, the more itchy it will become, which will often cause great pain to the patients. If the itching is really unbearable, you can also use cold compresses to relieve the pain.

2. Reasonable diet : This is also one of the care measures for children suffering from urticaria. When children develop urticaria, they should avoid eating foods high in protein. In addition, various spicy and seafood foods should also be avoided, otherwise the disease will worsen to varying degrees.

3. Avoid hot and cold stimulation : Weather changes and sudden changes in temperature will cause certain stimulation to the skin. Therefore, everyone must pay attention to keeping warm in daily life, otherwise it will often have a certain impact on the skin. After suffering from urticaria, you should choose to wear loose and breathable clothes.

3. Treatment of urticaria in children :

1. Oral antihistamines : such as loratadine, chlorpheniramine, cyproheptadine, etc., can compete for histamine in the body, thereby effectively relieving skin allergy symptoms. However, antihistamines do not inhibit the production of histamine and therefore cannot prevent recurrence of urticaria. Moreover, histamine products have a nerve-inhibiting effect, and adverse reactions such as dizziness and drowsiness are likely to occur after taking them. Long-term use can cause greater damage to the liver and kidneys.

2. Treatment with external medications : Most people will choose hormone ointments, such as dexamethasone ointment, Fuqingsong, etc. Although they can quickly control skin allergy symptoms, the allergic symptoms will recur once they are discontinued. Long-term use of hormone ointments will cause the skin to lose its normal defense and self-protection ability, and eventually lead to hormone-dependent dermatitis.

3. Traditional Chinese medicine treatment : Some traditional Chinese medicines with heat-clearing and toxin-eliminating effects are often used for treatment. Although it can clear out the dampness, toxins and damp heat in the body, unclog the circulation channels in the body and achieve the improvement of eliminating toxins and purging fire, it does not change the root cause of urticaria and therefore cannot prevent its recurrence.
