Do you have sneezing, itchy nose, runny nose, stuffy nose? Do you have sneezing, itchy nose, runny nose, stuffy nose, or red, itchy and watery eyes, dark circles under the eyes, loss of sense of smell or dizziness, headache, etc.? If so, you may be suffering from allergic rhinitis! Allergic rhinitis is a disease caused by inhalation of external allergens with sneezing, itchy nose, runny nose and nasal congestion as the main symptoms. The onset of the disease is seasonal or perennial due to the seasonal increase or decrease or persistence of allergens. As with allergic asthma, there is often a clear genetic allergy. The disease may be accompanied by itching of the conjunctiva, palate and external auditory canal during episodes of fashion. Do you have sneezing, runny nose, cough and chest tightness? Most people with asthma have a past history of allergic rhinitis. The onset of asthma is preceded by sneezing, runny nose, itchy nose, itchy eyes, tearing, and chest tightness. Due to the similarity of symptoms to respiratory infections or inflammation, patients lack knowledge and often neglect treatment at an early stage, which is also highly likely to be misdiagnosed. Asthma is a chronic airway inflammation that causes coughing, chest tightness, dyspnea and wheezing due to the hyperresponsiveness of the airways and the contraction of bronchial smooth muscle caused by triggering factors (e.g., dust mites, pollen and other allergens), resulting in airway narrowing and increased airway resistance. Allergic rhinitis and asthma are “one airway, one disease”. Allergic diseases: Allergic rhinitis and asthma are common respiratory allergic diseases, the incidence of which is increasing year by year in China. Allergic rhinitis, if not treated correctly and in a timely manner, can lead to memory loss, affect the intellectual development of children, and may develop into asthma, etc. According to clinical data, the risk of asthma is 8-10 times higher in patients with allergic rhinitis than in normal people, and a considerable number of asthma patients have allergic rhinitis symptoms before asthma attacks. Allergic asthma accounts for about 60% of asthma, mostly starts in childhood, and about 30%-50% of children’s disease will be delayed into adulthood. Repeated asthma attacks will seriously affect people’s normal life, work and study, lead to growth and development disorders in children, and will gradually evolve into chronic obstructive pulmonary disease or pulmonary heart disease, seriously endangering people’s health. Allergic diseases first need to identify the allergens causing the disease. Allergen screening is the first step in the diagnosis and treatment of allergic diseases, and once the allergens are identified, appropriate measures can be taken to avoid exposure.
