What to do if your baby has breast milk jaundice?

There is a kind of neonatal jaundice called breast milk jaundice, which generally appears 4~5 days after birth, and the gradually aggravated and elevated bilirubin can last for about 10 days, and then gradually decrease, and return to normal in 3~12 weeks.When the baby has breast milk jaundice, many mothers are worried, what is breast milk jaundice? Need to be dealt with?

Breast milk jaundice was first reported in the 60s of the 20th century, when the incidence was about 1%~2%, with the further understanding of breast milk jaundice, the incidence of human milk jaundice reported in the literature from the 80s has been increasing year by year. According to the literature, the incidence of jaundice in babies who are normally breastfed at 28 days of age is about 9.2%, which is actually much higher than the reported number.

Breast milk jaundice is characterized by an increase in unconjugated bilirubin in the blood after breastfeeding, presenting with jaundice. Breast milk jaundice can be divided into early-onset and late-onset types. The time of appearance of early-onset breast milk jaundice is 3~4 days after birth, and the peak time of jaundice is 5~7 days after birth; Late-onset breast milk jaundice appears 6~8 days after birth, the peak time of jaundice is 2~3 weeks after birth, and the jaundice resolution time can reach 6~12 weeks.

There are three main causes of breast milk jaundice:

1. Breast milk contains gestation-3α-20β diol, and the mother's breast milk of children with breast milk jaundice contains gestation3α-20β diol, which inhibits the activity of hepatic glucuronosyltransferase.

2. The content of unsaturated fatty acids in breast milk is high, and the content of unsaturated free fatty acids in the breast milk of children with breast milk jaundice is increased; Inhibition of hepatic glucuronosyltransferase.

3. The activity of β-glucuronidase in breast milk is high, and the activity of β-glucuronidase in breast milk is much higher than that of milk and formula milk, so that the bound bilirubin is decomposed, the reabsorption of the small intestine is increased, and the entero-liver circulation is increased. β-glucuronidase plays a major role in this.

How to prevent breast milk jaundice?

To prevent breast milk jaundice in the early stage, the first is to increase the number of feedings for newborns 3-4 days after birth, but the amount should not be too much each time. Sucking stimulates bowel movements and reduces bilirubin reabsorption. If the amount of breast milk is insufficient, supplemental formula or other milk substitutes should be given appropriately to save the infant from starvation and prevent cholestasis. Second, phenobarbital can be prevented early in neonates, and phenobarbital is an inducer of glucuronosyltransferase activity, which can reduce bilirubin reabsorption in newborns, reduce blood bilirubin levels, and prevent hyperbilirubinemia. Third, for children with existing breast milk jaundice, on the basis of not stopping breastfeeding, 1.5 grams of Smecta can be fed evenly with 10% glucose solution once every 8 hours, which can promote the early resolution of jaundice and ensure the healthy development of infants and young children.
