Although allergic rhinitis is not a serious disease, if it is ignored and allowed to develop without active intervention, once the disease progresses, it will bring many health problems to children and seriously affect their lives, recreation and studies. Allergic rhinitis has the following four main symptoms: itchy nose, runny nose, sneezing, nasal congestion, from babies shortly after birth to adults can get the disease, but despite this, the symptoms of pediatric allergic rhinitis are different from those of adults: pediatric allergic rhinitis is more of an itchy nose, runny nose, nasal congestion (nose is not ventilated), sneezing is not as obvious as adults. Since infants are young, some subjective symptoms such as itchy nose cannot be expressed clearly and accurately, so it depends on parents’ careful observation. For example, when the nose itches, they will show corresponding actions: mainly rubbing their nose, picking their nose, shrugging their nose and so on. For a child with allergic rhinitis, the symptoms may be more or less frequent, and may include only one symptom or more than one symptom, and the symptoms may be mild or severe. What are the health risks of allergic rhinitis for children? In allergic rhinitis, the nasal mucosa is congested and edematous, and the nasal discharge increases, making it susceptible to infection by viruses and bacteria. Because allergic rhinitis can recur and the symptoms are similar to those of the common cold, it is easy to be mistaken for a cold. Some medicines for colds also contain a small amount of anti-allergy drugs, especially when the cold is combined with allergic rhinitis, and the treatment of the cold is effective for allergic rhinitis at the same time. Allergic rhinitis is not effectively treated for a long time, and allergic rhinitis develops repeatedly with repeated fevers and colds, which leads to repeated respiratory tract infections and chronic cough. In addition, it often causes acute and chronic infectious rhinitis, sinusitis, etc. Allergic rhinitis often coexists with allergic conjunctivitis, which is manifested by: itchy eyes and rubbing of the eyes. Since the essence of allergic rhinitis is caused by allergens, it can be said that allergic rhinitis is the manifestation of allergy in the nose. Skin allergy and eczema are also a kind of allergy. On the surface, it seems that many symptoms of allergy are manifested in a certain part of the body such as skin, nose and eyes, but allergic diseases are systemic and systematic diseases. Children with allergic rhinitis do not only have symptoms in the nose, but if they do not receive timely and standardized treatment, they can easily develop asthma and even affect their heart and other systems. In children with allergic rhinitis, it can also lead to adenoid hypertrophy, while snoring and, in severe cases, serious complications such as sleep apnea at night can occur. As allergic rhinitis is not effectively controlled, repeated colds and fevers, rhinitis and sinusitis lead to inflammation and edema of the eustachian tube, which can lead to otitis media and hearing loss in children. Repeated respiratory infections, adenoid hypertrophy, sleep apnea, etc. seriously affect the quality of sleep, the relative ischemia and hypoxia of cardiovascular and cerebrovascular, allergies, etc., which can lead to myocardial damage, and also affect the growth and development of children, thus affecting the growth. School-age children’s academic performance decreases. Because the symptoms of allergic rhinitis are similar to those of the common cold, and some of them are insidious, they are easily overlooked. However, because allergic rhinitis can lead to so many diseases and complications, which seriously affect the physical and mental health of children, it should be paid attention to by parents and doctors alike. This also shows that allergic rhinitis is a disease that should not be underestimated. To summarize, pediatric allergic rhinitis can lead to the following diseases and complications: 1) recurrent respiratory infections and chronic cough; 2) acute rhinitis and sinusitis; 3) otitis media and hearing loss; 4) asthma; 5) adenoid hypertrophy; 6) myocardial damage; and 7) stunted growth.
