What should I do if my baby has a stuffy nose and runny nose?

Nasal congestion and runny nose in infants may be caused by seasonal changes, environmental factors, common colds, allergies, or acute sinusitis. These conditions can be improved according to the specific situation. It is recommended to seek timely medical consultation and follow the guidance of a physician for treatment.

1. Seasonal changes: Fluctuations in temperature and humidity during seasonal transitions can easily irritate an infant's nasal passages, leading to nasal congestion and runny nose. It is recommended to maintain indoor air humidity by using a humidifier. When going outdoors, ensure proper warmth and avoid direct exposure of the infant to cold, dry air.

2. Environmental factors: Dry air, smoke, and exposure to secondhand smoke can irritate the nasal mucosa of infants, causing mucosal congestion and increased secretions, which may result in nasal congestion and runny nose. It is recommended to improve the living environment by maintaining fresh and moist air and avoiding smoking environments to reduce secondhand smoke exposure.

3. Common cold: Usually caused by viral infections, common colds stimulate immune responses in the nasal passages, leading to inflammation of the nasal mucosa and increased secretions, which result in nasal congestion and runny nose. Symptoms may include cough, fever, sore throat, and loss of appetite. It is recommended to administer antiviral oral solutions, Lianhua Qingwen capsules, Ganmaoling granules, or other medications to the infant under the guidance of a physician.

4. Allergies: Contact with allergens such as pollen or dust mites can trigger allergic reactions in the nasal mucosa, causing congestion, swelling, and increased secretions. Symptoms may include sneezing, nasal itching, and itchy eyes. It is recommended to administer vitamin C tablets, boric acid zinc oxide ointment, flufenamic acid butyl ester ointment, or other medications to the infant under the guidance of a physician to alleviate discomfort.

5. Acute sinusitis: Bacterial infection can cause acute sinusitis, where the inflammatory response blocks the sinus openings, preventing normal drainage of secretions and causing nasal congestion and runny nose. Symptoms may include facial pain, headache, and fever. Parents may administer penicillin V potassium granules, amoxicillin granules, azithromycin granules, or other medications to the infant as directed by a physician.

In daily life, it is important to maintain fresh and moist indoor air and avoid exposing the infant to allergens to prevent nasal congestion and runny nose.
