Infant spitting up out of the nose usually does not affect the lungs, but if spitting up occurs for a long period of time, it may lead to milk accidentally entering the lungs and aspiration pneumonia.
Infant spitting up is mostly physiological, which refers to the phenomenon of part of the milk or food returning from the stomach to the mouth shortly after breastfeeding.
As infants are not yet mature, their stomachs are small and in a horizontal position, and physiologic spitting up can occur. In general, if an infant’s milk spits up briefly out of the nose and is not inhaled into the lungs, it usually does not affect the lungs and there is no need to worry. Parents can burp the baby after feeding to avoid the baby lying flat immediately.
If the infant has spat up milk for a long time, as the infant will cry and lose appetite, this may lead to the milk mistakenly entering the lungs and choking and coughing, and in serious cases, it may induce aspiration pneumonia, which will affect the lung function.
Therefore, if the baby spits up, parents should pay attention to the situation. When spitting up, you need to keep the baby’s airway open, ensure the correct feeding position, and observe the baby’s physical condition after feeding.
