Children can't expectorate, often swallow, will it affect their health?

The child has phlegm, which is difficult to discharge from his throat. Sometimes even if you cough up phlegm, you will swallow it because you don't know how to spit it out. Many parents worry that this will affect their children's health. They want to know how the baby will swallow sputum, and also want to know the correct method of sputum discharge. As long as the child's sputum can be discharged from the respiratory tract, it can be regarded as successful sputum discharge. Children don't excrete all their phlegm.

Let the child sleep on his side and take out sputum from the trachea. At the same time, pay attention to pat the child on the back. The racket back needs to be hollow, from bottom to top and from outside to inside. After patting, the child will swallow the sputum and then excrete it through defecation. Let children drink plenty of water, because drinking plenty of water can dilute sputum, thus better eliminating phlegm. Children can be atomized. The purpose of atomization is to dilute sputum, which is a good way to eliminate phlegm in children. But some children may not be willing to cooperate with atomization. Therefore, parents may feel uncomfortable when atomizing their children. Sputum is the garbage of respiratory tract, including dust, smoke, bacteria, viruses, fungi, exfoliated cells, necrotic tissues, blood cells, purulent substances in respiratory tract and lung tissues, which is very unfavorable for swallowing.

There are mucous glands and cilia in the respiratory mucosa. Mucous glands secrete mucus and serous fluid, which are also attached to small particles or bacteria that enter the respiratory tract with the air. The cilia on the mucosa will move upward. This ciliary body movement moves mucus and foreign bodies upward to clear the respiratory tract. Physiologically, phlegm is a mixture of mucus, serous fluid and foreign bodies secreted by mucus glands. Long-term swallowing of phlegm will affect the body. Although the body has the ability of self-purification and the sputum is not as dirty as expected, it is better to spit it out. This road is very clean. Spitting everywhere not only makes people feel uncivilized, but also increases the burden on sanitation workers. Therefore, under normal circumstances, sputum should be spit directly into the trash can. Or wrap your mouth with a tissue and spit out the sputum. After all, sputum contains bacteria, which can prevent sputum from contacting with air and prevent the spread of virus.
