What are the causes of physiological jaundice in newborns? A brief analysis of the four causes of physiological jaundice in infants

Neonatal jaundice is divided into physiological jaundice and pathological jaundice. The causes of physiological jaundice are roughly divided into: immature liver function, rapid increase of bilirubin in the body, imperfect liver circulation, and combination of digestive system. The symptoms of jaundice will disappear completely after a few weeks. If the symptoms tend to worsen, it is recommended to go to the hospital for treatment in time. Feed more breast milk, drink more water and get more sun on weekdays.

It is common for newborns to have jaundice. Jaundice is divided into physiological jaundice and pathological jaundice. Physiological jaundice is a manifestation of the normal development of newborns. Usually, physiological jaundice will gradually disappear with growth and development, and no medical intervention is required. So what are the causes of physiological jaundice in newborns? Let's talk about it in detail.

The basic cause of physiological jaundice in newborns is the massive destruction of red blood cells, which leads to a sharp increase in the bilirubin content. After birth, the child is no longer connected to the mother, and all excretion of substances must be done by the mother. The child begins to actively take in oxygen, and a small amount of red blood cells can transport enough oxygen, so a large part of the red blood cells will be destroyed, and the amount of bilirubin released will increase.

Another cause is the immature liver function of the newborn. The bilirubin produced by the red blood cells in the body needs to be transferred through the liver before it can be excreted from the body. Most of the bilirubin that has not been processed by the liver will accumulate in the body. As the accumulation increases, the skin of the child will show symptoms of jaundice. Usually, physiological jaundice will gradually disappear as the liver function of the child gradually develops, usually in about half a month, and rarely more than half a month.

The third reason is that the digestive system of the newborn absorbs a large amount of unconjugated bilirubin and transports it into the blood, which causes a high level of bilirubin in the blood. Newborns usually develop jaundice 3 to 5 days after birth, and the symptoms of jaundice are more obvious after 5 days.

Finally, the reason is that the enterohepatic circulation is not perfect. The intestinal flora of newborns is not perfect when they are born, and the bilirubin in the intestine cannot be converted into secretions. Moreover, the unconjugated bilirubin will be absorbed by the intestinal wall and transported to the liver again, causing jaundice in the child.

The four major causes of neonatal jaundice are: red blood cells are destroyed and bilirubin is released, the liver function of the newborn is not mature enough, the digestive system absorbs unconjugated bilirubin, and the enterohepatic circulation is not perfect. Observe the physical symptoms of the child more often on weekdays. If the condition begins to worsen, please go to the hospital in time for treatment and relevant treatment. Drink more water, feed more breast milk, and get more sun.
