For allergic rhinitis, it is first necessary to go to the hospital for a detailed examination of allergen antibody tests to identify the substances causing the allergy. If you are allergic to mangoes, then you must avoid eating mangoes. Allergic rhinitis is mainly caused by a decrease in the body's immunity and resistance, leading to localized symptoms after the nasal and oral cavities come into contact with an allergen. Patients may experience symptoms such as sneezing fits in the morning, runny nose with clear mucus, bilateral nasal congestion, nasal itching, and eye itching. During the examination, pale and swollen nasal conchae mucosa can be observed, and the prick test is positive. In terms of treatment, during the acute phase of allergic rhinitis, symptomatic antiallergic treatment is required first. Patients also need to avoid allergens, wear masks, avoid spicy and irritating foods, exercise regularly to enhance immunity and resistance, and avoid catching colds, which can gradually lead to improvement.
