Experts in the north of China have entered the peak period of pollen allergy: be alert to these symptoms
2023-03-14
The spring is warm, everything is reviving, and the annoying spring allergy also follows. According to the pollen monitoring data of medical institutions, Beijing has entered the spring pollen peak. Wang Xueyan, Vice Chairman of the Allergy Branch of the Chinese Medical Association, said that the pollen monitoring data showed that the concentration of the main allergenic pollen in the air reached more than 3600 grains per thousand square millimeters on March 8. The main allergenic pollen was cypress pollen, elm pollen and poplar pollen. In recent days, the number of outpatients has increased three times than usual, and some patients have severe symptoms. With the rise of temperature, northern China will gradually enter the peak period of pollen. Allergic rhinitis has obvious seasonal characteristics. Experts remind that spring is the season of high incidence of some respiratory diseases. Among them, the prevalence of allergic rhinitis has increased significantly in recent years, which needs attention. Allergic rhinitis is a non-infective inflammatory disease of nasal mucosa. The main symptoms are paroxysmal sneezing, clear water like mucus, itchy nose and stuffy nose. Some patients may have eye symptoms, including itching, tears, redness and burning sensation. Some patients may be complicated with bronchial asthma, accompanied by cough, dyspnea and chest tightness. Allergic rhinitis is divided into perennial allergic rhinitis and seasonal allergic rhinitis. The allergens of perennial allergic rhinitis are mostly dust mites, cockroaches, animal fur, etc., without obvious seasonality. The allergens of seasonal allergic rhinitis are mostly plant pollen, and seasonal pollen exposure is the main cause of pollinosis. Wang Xueyan, Vice Chairman of the Allergy Branch of the Chinese Medical Association, said that perennial allergic rhinitis is different from seasonal allergic rhinitis. Perennial allergic rhinitis occurs all year round, and the same symptom occurs repeatedly, which is mainly caused by exposure to dust, cleaning, air conditioning, and dirty and poor environment; Seasonal (allergic) rhinitis has a certain relationship with the amount of pollen contact. It has obvious seasonality and timeliness. It will come on in this season, and it will not cure itself after this pollen season. Pollen allergy symptoms are easily confused with colds. Experts pointed out that patients with seasonal allergy in the high incidence season should take scientific protection in time: wear masks and goggles when going out, take off clothes when entering the room, wash hands, eyes and nose, and minimize contact with pollen. In addition, experts also suggested that respiratory diseases were high in spring, and pollen allergy symptoms were easily confused with colds, so we should be vigilant to avoid delaying treatment. Spring is the time of high incidence of respiratory diseases. The symptoms of allergic rhinitis are similar to those of colds. It is easy to be confused and lead to the misuse and abuse of antibiotics, thus delaying the disease. In this regard, experts pointed out that pollen allergy has obvious seasonal and temporal characteristics, lasting for at least 3 weeks, without fever, headache, muscle soreness and other symptoms. If certain related symptoms occur regularly and repeatedly, be highly alert to allergies and seek medical advice in time. Wang Xueyan, Vice Chairman of the Allergy Branch of the Chinese Medical Association, said that patients with hay fever should go to the hospital for medical treatment in time, identify the allergen and receive standardized diagnosis and treatment. Drug control and symptomatic treatment are the main methods in the pollen peak period, and biological agents can be considered for individual severe patients. Specific immunotherapy is mainly used after the pollen remission period. (Xinhua News Agency)
