What are the causes of neonatal jaundice?

1. Physiological reasons

During the fetal period, the mother will produce a large number of immature red blood cells in order to meet their own needs for oxygen. After the baby is born, red blood cells will slowly rupture, and then there will be a lot of bilirubin released into the blood, so that the blood bilirubin content increased. In addition, the liver of the newborn baby is not fully mature, and the metabolic capacity is weak, which leads to neonatal physiological jaundice. There is no need to worry about such problems, let the child eat more breast milk and urinate more.

Septic jaundice is caused by bacterial infection, children jaundice will continue.


Usually, children should be allowed to bask in the sun, because under the action of ultraviolet light, the excess bilirubin in the body can be directly converted into water-soluble substances, which can be discharged from the body with the urine.
