What are the main common allergic diseases in children? Pediatric eczema, food allergies, allergic rhinitis (allergic rhinitis) and asthma generally occur at an earlier age in children with eczema and food allergies, and later in children with allergic rhinitis and asthma. First of all, these children often have a genetic background called “atopic”. Studies have shown that children with eczema are 2.5 times more likely to develop asthma than children without eczema; the presence of allergic rhinitis tends to worsen asthma, doubling the number of asthma emergency visits and increasing asthma emergency medication. The presence of allergic rhinitis tends to worsen asthma and can double the number of emergency asthma visits and increase the number of emergency asthma medications for patients. Allergic diseases affect the body in many ways. Chronic allergic inflammation of the upper respiratory tract can cause lymphoid tissue hyperplasia, leading to adenoid and tonsillar hypertrophy, and these in turn can lead to obstructive sleep apnea, mouth breathing, irritation of the pharynx and dental malformations. Allergic rhinitis can also cause sleep disturbances in affected children, leading to secondary daytime fatigue, which in turn can negatively affect their mood, learning and memory. How can pediatric allergic diseases be prevented? Pediatric allergic diseases, it is important to avoid contact with allergens. Pediatric eczema and food allergy are often related to the patient’s allergy to milk protein, breastfeeding is more important for these patients, if you cannot continue breastfeeding, you can choose deeply hydrolyzed milk powder or even amino acid milk powder; allergic rhinitis and asthma are often caused by inhalant allergens, outdoor inhalant allergens mainly include pollen and fungi, indoor allergens mainly include Mites, animal dander, insects and fungi. The use of non-permeable bed covers, improved indoor ventilation, avoiding the use of carpets, and controlling humidity to prevent the accumulation of mold and other measures are conducive to the control of indoor allergens. How is the diagnosis of pediatric allergic diseases made? The most common and safe clinical method is the skin prick test to check for allergens.
