After the birth of a baby, parents should not only pay attention to the feeding of the child, but also observe and see if the child has any abnormal symptoms in daily life. Some parents may notice that their baby's lips turn black, which can cause great concern. So, what causes a baby's lips to turn black?
There are many factors that can cause a baby's lips to turn black, and the specific cause needs to be determined based on the baby's symptoms. Some children may also have darker or even blackened lips during normal times. At this point, as long as you pay more attention to your child's diet and sleep, the symptom of blackened lips can quickly disappear.
Black lips in infants may also be caused by pathological factors, known as cyanosis, which may be caused by cardiovascular disease. For example, if a child has congenital heart disease and abnormal heart development leads to shunting between arteries and veins, it can cause the child to experience blackening of the lips due to lack of oxygen. Generally, the symptom of blackening will worsen when crying, indicating pulmonary hypertension and the need to go to the hospital for cardiac ultrasound.
Respiratory diseases can also cause black lips in infants. For example, when a child suffers from wheezing pneumonia, the child's lung ventilation function will decrease, which can cause insufficient oxygen in the blood, resulting in symptoms such as black lips, cough, phlegm, and choking on milk.
