My child has a runny nose, what's going on?

The arrival of a newborn always brings infinite joy to a family, and the health of the newborn is also a concern of the whole family. But sometimes mothers will find that their babies often have clear runny noses. They don’t know if this is normal, so they are very worried about the baby’s health. In fact, it is normal for babies to have green snot, and parents don’t need to worry too much.

Under normal circumstances, the human nasal mucosa is constantly secreting mucus to moisten the nasal membrane, moisten the inhaled air, and stick to the dust, microorganisms and microorganisms inhaled from the air. This is snot. A normal person secretes about several hundred milliliters of nasal mucus every day, but all of this mucus flows along the direction of the movement of the cilia of the nasal mucosa, to the posterior nasal aperture and then to the pharynx. Due to evaporation and drying, it is generally not seen flowing out of the nasal cavity. The nasal mucosa of children has more blood vessels and secretions than adults. In addition, the nervous system's regulatory function on nasal mucosal secretion and ciliary movement is not yet fully developed. Children are not good at wiping their noses by themselves, so they often have clear nasal discharge. This is a normal physiological phenomenon and there is no need to worry.

If there are two lines of snot hanging under the child's nostrils all day long or yellow-green purulent snot flows out, it is a sign of illness. People who have yellow-green, purulent nasal discharge for a long time may suffer from sinusitis. Frequent runny nose may be caused by a lack of vitamin A and vitamin B, and treatment with these two vitamins can be effective. Allergies to inhaled dust can cause a large amount of clear nasal discharge within a short period of time. A small number of children with foreign objects in their nasal cavity may also have a runny nose frequently. What should be noted most is that some children with nasopharyngeal lymphadenopathy also often have a runny nose, but they also have symptoms such as severe snoring, dull face, and flat nose, which can seriously affect their development and posture and should be treated in time. The health of children has always been a concern for parents, so we should be more cautious when taking care of children. It is recommended to provide children with a clean and ventilated living environment. If it is the peak period of infectious diseases, it is recommended not to take children out frequently, because children's resistance is lower than that of adults.
