It’s autumn again, and the autumn girl has come around with her colorful clothes. You can’t wait to pack your bags and bring your family to spend a nice weekend in the countryside after being held in the heat all summer. However, as soon as the holiday is over, many friends have stuffy noses, runny nose, sneezing, itchy around the eyes and nose – allergic rhinitis strikes. ”Autumn wind rises, rhinitis comes”, the poet’s pen or bleak or cheerful autumn, the joy of harvest in the hands of farmers, the bright and colorful autumn in the eyes of travelers, but it has become a difficult season for patients to worry about. Allergic rhinitis, also known as allergic rhinitis, has a certain genetic predisposition and often shows a family susceptibility. It is a chronic inflammatory disease of the nasal mucosa involving a variety of immunologically active cells and cytokines caused by the exposure of susceptible individuals to allergens. Allergic rhinitis is classified as perennial or seasonal according to the time of onset. The former is associated with pollen, including wind-pollinated pasture, trees, weeds and fungal spores, while the latter is often caused by dust mites, animal dander, etc. Its global average incidence is about 10%-25%, with the human ecological environment and physical changes, there is a trend of increasing year by year. The typical symptoms of allergic rhinitis are paroxysmal sneezing, profuse watery mucus, followed by nasal congestion and nasal itching, and in some patients, loss of sense of smell, but mostly temporary. In addition, about 70% of patients have extra-nasal symptoms such as itchy eyes, tearing, itchy throat and cough. Due to the non-specific nature of its clinical manifestations, a considerable number of patients “thought they took some medicine after catching a cold, and the symptoms disappeared after two or three days, but a week later there were symptoms of nasal congestion, runny nose, sneezing, intranasal itching and fever, which have become heavier and heavier after two months”; in fact, it is your nose that is “allergic”. “Allergy”. Two methods are commonly used to treat allergic rhinitis clinically. The first is to stay away from allergies. If you are allergic to a specific substance such as animal fur, you can prevent it by avoiding contact. For seasonal allergic rhinitis, a common allergen is pollen. When the pollen level in the air is high (5 to 10 am is the peak pollen time, and on windy days, the pollen concentration in the air is correspondingly high), you should minimize outdoor activities or use air conditioners or reduce the number of window openings and use air filters as much as possible. For the national population, a common allergen for perennial allergic rhinitis is dust mites. Dust mites are commonly found in people’s daily life, and the allergens include mite bodies, mite molted skin, lysates of dead mites and excretions and secretions of live mites, etc. Diligent drying of bedding sheets can play a preventive role. For patients who cannot avoid contact with allergens, they have to apply anti-allergic drugs. Patients with mild symptoms can apply local drugs, that is, nasal spray treatment, and those with severe symptoms can take some anti-allergic drugs orally, and those who still cannot control their symptoms can use a combination of both. For patients who should not be treated with medication, such as pregnant women, newer treatments such as nasal rinses can be used. Usually, for patients with poor effect of medication, doctors will suggest you to check allergens, and if specific allergic principles can be detected, desensitization therapy is feasible, and after continuous and long time desensitization therapy, allergy symptoms can usually be reduced by medication. ”Sneezing and runny nose” sounds like a minor annoyance, but if it is not effectively controlled, it can be complicated by nasal polyps and sinusitis in the long run, and about 8% of patients with allergic rhinitis can further develop into serious diseases such as bronchial asthma, which is a real problem for patients!
