What is the cause of neonatal jaundice?

Nowadays, many newborns are prone to jaundice, which can be divided into physiological jaundice and pathological jaundice. There are many reasons for this condition in babies, and only by understanding the specific reasons can we treat it in a targeted manner. Common causes include hypoxia, breastfeeding, infection factors and congenital bile duct malformations.

1. Hypoxia

Generally speaking, if physiological jaundice occurs in the baby's body, it is mainly caused by hypoxia. This is mainly because most babies are in a state of hypoxia in the mother's womb, so the number of red blood cells in the human blood will gradually increase. In the past, it would cause an increase in the amount of bilirubin when the baby is born, so physiological jaundice would occur.

2. Breastfeeding

Sometimes breastfeeding can cause jaundice in children, which is a very special pathological jaundice phenomenon. The reason for this is that breast milk contains a substance called pregnanediol hormone, which causes the bilirubin in the human blood to not be discharged in time, so the baby's skin and sclera will become more panic. Pathological jaundice will eventually occur.

3. Infection Factors

Infectious factors are also one of the common causes of pathological jaundice in many infants. It is mainly because the body is infected by bacteria or viruses, which causes damage to liver cell function, so the disease breaks out. Generally speaking, at this time, the baby is infected in the mother's body, and the more common viral infection is hepatitis B virus.

4. Biliary tract malformations

In daily life, a small number of infants have congenital biliary tract malformations, which are more likely to cause obstructive jaundice. The more common biliary tract malformations are mainly congenital biliary atresia.
