Pediatric nasal congestion and sneezing are mostly caused by upper respiratory tract infections or allergic rhinitis. Parents can promptly take their children to the doctor for examination and symptomatic treatment. Common causes: 1. Upper respiratory tract infection: children with symptoms of nasal congestion and sneezing, accompanied by fever and headache symptoms, are mostly due to upper respiratory tract infection caused by viral infection; 2. Allergic rhinitis: due to allergy to pollen, dust mites, cotton wool, etc. When contacting these allergens, symptoms of nasal congestion and sneezing will occur when the nasal mucosa becomes congested and edematous. Treatment: 1. Upper respiratory tract infection: You can use a hot towel to warm the root of the nose to relieve the symptoms of nasal congestion, or you can use saline nose spray under the guidance of a doctor. If the symptoms are not reduced, you can follow the doctor’s instructions to take oral aminophenanthramine granules or cetirizine oral solution for treatment; 2. Allergic rhinitis: you can use antihistamine drops locally under the doctor’s guidance to relieve nasal mucosal congestion and edema, and take oral cetirizine syrup, loratadine dry suspension and other antihistamine drugs for treatment. Caution: Children should drink more water, rest more and keep warm during treatment. Pay attention to nutritional supplements, eat more vegetables and fruits containing vitamin C, such as tomatoes, kiwi, apples, celery, etc., and strengthen physical exercise to help improve body resistance and avoid disease damage.
