With the arrival of autumn, many patients with allergic rhinitis are facing the problem of seasonal recurrence. Experts remind patients with rhinitis to be cautious of the "hidden hazards" of autumn pollen and to strengthen their response through scientific physical protection, standardized medication, and other methods. Chen Xiaowan, Director of the Ear, Nose, Throat, Head and Neck Surgery Department at the First Hospital of Lanzhou University, introduced that recently, with the cooling weather and increasing temperature fluctuations in many parts of the country, the pollen concentration of Artemisia plants has risen, and the number of patients seeking medical treatment for allergic rhinitis has significantly increased. The temperature fluctuates significantly during the transition period between summer and autumn, with dry and windy air and soaring pollen concentration. ”Chen Xiaowan said. According to the pollen allergy index of China Weather Network, some northern cities have high pollen levels recently, which can easily cause allergies. It is recommended to reduce outdoor activities and continue to use medication in a standardized manner. Experts explain that pollen is not only present in spring, but also reaches its peak in different seasons for different types of plants. In autumn, it is not the flowers that cause allergies, but rather wind borne allergens such as artemisia, humus, and ragweed. A single artemisia plant can produce hundreds of millions of pollen grains, which can drift hundreds of kilometers with the wind and easily cause strong allergic reactions. Tao Zhongbin, Deputy Director of the Children's Intensive Care Unit at the First Hospital of Lanzhou University, said that the main symptoms of rhinitis are a large amount of watery nasal discharge, a nose that looks like an "unclosed faucet", continuous severe sneezing, and itching in the nose, eyes, ears, and deep throat. Experts remind that allergens should be kept away through physical protection and other methods. Early morning and dusk are periods of high pollen concentration, so outdoor activities should be minimized as much as possible. Before going out every day, check the weather forecast for the "pollen index" and try to minimize going out during periods of high pollen concentration. Wear a mask and well sealed glasses when going out, which can effectively block pollen. According to experts, nasal glucocorticoid spray is the first-line drug for treating allergic rhinitis, which can effectively control most nasal symptoms. This type of medication is used locally with minimal systemic absorption, and can be safely used under the guidance of a doctor, including in children. For patients with moderate to severe persistent allergic rhinitis, allergen specific immunotherapy (desensitization therapy) can be considered when the allergen is identified. By continuously administering allergen extracts to help the immune system gradually adapt, this is currently the only etiological therapy that can change the course of the disease, "said Chen Xiaowan. Chen Xiaowan stated that oral anti allergic drugs can not only quickly alleviate symptoms such as nasal itching and runny nose, but also improve extranasal symptoms such as eye problems. All medications must be used under the guidance of a doctor and treated according to medical advice. Do not stop taking medication immediately after symptoms have improved. (New Society)
