Among them, eczema, allergic rhinitis, and bronchial asthma are the most common among children. For example, the prevalence of bronchial asthma in children aged 0-14 is 1.56%. The prevalence of allergic rhinitis in children is as high as 7.5%. Allergic diseases have become a major public health problem affecting children’s health.

When parents are allergic, their children are 70% likely to be allergic; if the mother is allergic, 50% of their children will be allergic; if their father is allergic, their children have 30% chance of becoming allergic . Therefore, for children who have a higher risk of allergies from their parents’ genetic factors, they should prevent allergies in all aspects of clothing, food, housing and transportation.

  Children’s allergy treatment
  of allergic diseases in children, should be based on the severity of the disease, age and other different standard treatment under the guidance of professional doctors.

During the treatment, allergens should be avoided, and the drug dosage should be controlled strictly according to the doctor’s advice. If necessary, allergen desensitization treatment can also be selected.
  If your child suffers from allergic rhinitis or allergic asthma, the sooner the treatment is, the better, and it must be cured before puberty. Otherwise, as the age grows, the immune system develops gradually, and the plasticity becomes worse and worse, and the chance of cure will become smaller and smaller. When treating children with asthma, it is necessary to consider whether there are other allergies such as rhinitis and whether combined treatment is required to achieve a multiplier effect with half the effort. But should try to avoid at the same time oral inhalation of the treatment of asthma and nasal inhalation of drugs for the treatment of allergic rhinitis. For moderate allergic rhinitis, oral leukotriene modulators should be the first choice. The antihistamine drug loratadine has a good effect in controlling skin, nose, eyes, and gastrointestinal allergies, so it is optional. For patients with obvious nasal congestion, nasal drops such as 1% ephedrine drops can be used (infants and young children should be appropriately diluted), and traditional Chinese medicine can also be used for treatment, and an experienced Chinese medicine doctor can be used to treat it according to symptoms and signs.
