Patient's question:
Patient Gender:Medical History: My child is 1.5 years old. A month ago, she had a fever, and after receiving intravenous fluids, she recovered in two days. However, she has been constantly running a nose. I gave her a medicine called "Hao Dawawa," but after more than 20 days, there has been no improvement. What could be the reason? What should I do?
Doctor's answer:
Hello:A normal person secretes about hundreds of milliliters of mucus daily. However, this mucus flows in the direction of the ciliary movement of the nasal mucosa, from the posterior nasal to the pharynx. With evaporation and drying, it is generally not visible as it flows out of the nose.
Children's nasal mucosa has richer blood vessels than adults, and they produce more secretions. Additionally, their nervous system's regulation of mucus secretion and ciliary movement is not yet fully developed, and they are not good at wiping their noses themselves. Therefore, frequent clear nasal discharge is a normal physiological phenomenon and nothing to worry about.
If a child's nostrils are always hanging with two lines of mucus or if yellow-green pus-like nasal discharge is observed, it indicates a pathological condition. Long-term yellow-green pus-like nasal discharge may suggest sinusitis. Frequent white nasal discharge could be due to a lack of vitamins A and B. Treatment with these vitamins can be effective. Allergic reactions to inhaled dust may cause a large amount of clear nasal discharge in a short time. A few children with foreign bodies in their nasal cavities may also frequently have nasal discharge. Most importantly, some children with nasal-pharyngeal lymphadenopathy may also frequently have nasal discharge, but they often accompany severe snoring, dull facial expressions, and small, flat noses. These conditions can severely affect development and posture, requiring timely treatment.
