Allergic diseases, also known as allergic diseases, are a common type of chronic disease today. It manifests itself as an overly strong immune response to one or more substances in the environment and leads to damage of tissues and organs, thus affecting normal physiological functions. The occurrence of allergic diseases often follows a natural process of gradual deterioration. People with allergies mainly show food allergy in infancy, with eczema, vomiting, diarrhea, etc.; after 4-5 years of age, they gradually shift to allergy to inhaled allergens, with respiratory to allergic symptoms such as nasal congestion, runny nose, cough, wheezing, etc. Some of the patients with allergic rhinitis will gradually progress to allergic asthma, and repeated asthma attacks will eventually lead to chronic obstructive pulmonary disease and pulmonary heart disease, etc., involving more tissues and organs, and will also be complicated by other diseases and even threaten life.
