Patient's question:
The baby is 10 months old. They have a cold and a runny nose that hasn't gotten better. The doctor says it might be nasal sensitivity. I don't know what to do. Thank you!Doctor's answer:
Normal people secrete about hundreds of milliliters of mucus daily, but these mucus flows along the direction of the ciliary movement of the nasal mucosa, from the posterior nasal to the pharynx, and due to evaporation and drying, it is generally not visible flowing out of the nose. Children's nasal mucosa has richer blood vessels than adults, and their secretions are also more abundant. Additionally, the regulatory function of the nervous system on the secretion of the nasal mucosa and ciliary movement is not yet fully developed, and children are not good at wiping their noses themselves, so they often have clear nasal discharge, which is a normal physiological phenomenon and does not need to be worried about.If a child's nostrils are always hanging with two lines of mucus or if they are discharging yellow-green pus-like nasal discharge, this indicates a pathological condition. Long-term discharge of yellow-green pus-like mucus may suggest sinusitis. Frequent discharge of white mucus could be due to a lack of vitamins A and B. Treatment with these two vitamins can be effective. Allergic reactions to inhaled dust can cause a large amount of clear nasal discharge in a short period. A small number of children with foreign bodies in their nasal cavity may also frequently have nasal discharge. The most important thing to note is that some children with nasal-pharyngeal lymphadenopathy also frequently have nasal discharge, but they are accompanied by severe snoring, dull facial expressions, and small, flat noses, which can severely affect their development and posture. Timely treatment is necessary.
