Allergic diseases, also known as anaphylaxis, are chronic systemic diseases that affect 20-40% of the population at some point in their lives, including infantile eczema, contact dermatitis, allergic rhinitis, bronchial asthma, acute urticaria, food/drug allergies, and anaphylaxis. Allergic diseases are influenced by a variety of factors such as genetics and environment. They usually follow a natural process of gradual development: Infancy: mainly allergies to various foods such as milk, eggs, beans, fish, shrimp, etc., manifesting as eczema, atopic dermatitis, vomiting, diarrhea, etc. After 3 years of age: Allergy to inhaled allergens such as dust mites, molds, pollen, etc. begins, manifesting as respiratory symptoms such as nasal congestion, runny nose, cough, breath-holding, asthma, etc. Overall, about 80% of children with atopic dermatitis will develop further into respiratory allergic diseases. The majority of patients with atopic rhinitis will gradually progress to asthma, and some children will start with asthma directly. Recurrent asthma attacks will eventually lead to chronic obstructive pulmonary disease or pulmonary heart disease, etc., involving multiple organs and even threatening life.
