What should we pay attention to when children have urticaria?

It is actually quite common for children to suffer from diseases such as urticaria. Parents need to pay more attention to their children's health during their growth, and detect and treat them in a timely manner. When children develop urticaria, the first thing to do is to find out the cause, because the occurrence of urticaria is related to many factors, such as drugs, temperature, sun exposure, etc. Only by finding the right cause can it be better treated.

① Cause : Urticaria in children is induced by drugs, cold, hot sun exposure, mental stress, etc., and urticaria associated with systemic diseases is much less common than in adults.

② From the course of the disease , urticaria in children is mostly acute urticaria. However, as they age, children and adolescents may suffer from worsening allergic eczema and asthma, or take medications (such as penicillins and sulfonamides), which may cause urticaria, which may gradually change from acute urticaria to chronic urticaria. Adults are more likely to suffer from chronic urticaria and drug-induced urticaria than children.

③The course of some special types of urticaria is also shorter than that of adults: for example, manual scratch disease and skin scratch disease in children generally last for 2-4 weeks, while in adults it lasts for several months or even years.

④ Urticaria with genetic tendency: It often starts from infancy, but the incidence is relatively rare. Solar urticaria and cholestatic urticaria (small urticaria) are also less common than in adults. However, aquagenic urticaria is more common in adults because children like to play in water.

⑤ From the perspective of prevention and treatment: It is easier to find the cause of urticaria in children, and the course of the disease is shorter. Therefore, compared with adults, the medication is simpler, the treatment time is shorter, and it is easier to prevent and treat.
