With the increasing rate of breastfeeding, the incidence of breast milk jaundice has been rising year by year, currently reaching 20-30%. It has also become one of the main causes of hyperbilirubinemia in hospitalized newborns. Although the prognosis of this condition is generally good and only severe cases require treatment, attention should still be paid to ensure the successful promotion of breastfeeding.

bubble_chart Pathogenesis

The main reasons are insufficient breast milk, delayed initiation of breastfeeding, and delayed passage of meconium. This is primarily due to the high content of β-glucuronidase in breast milk, which hydrolyzes conjugated bilirubin into unconjugated bilirubin, forming an active enterohepatic circulation.

bubble_chart Clinical Manifestations

In cases of hyperbilirubinemia occurring after birth with no other apparent cause during breastfeeding, bilirubin levels often reach 256.5–342 μmol/L (15–20 mg/dL). The newborn generally appears healthy, feeds well, and shows normal growth and development. Jaundice may persist for 3 weeks to 3 months.

In cases of hyperbilirubinemia occurring after birth with breastfeeding and no other identifiable cause, bilirubin levels often reach 256.5–μmol/L (15–20 mg/dL). The newborn generally appears healthy, feeds well, and shows normal growth and development. Jaundice may persist for 3 weeks to 3 months.

bubble_chart Treatment Measures

Breastfeeding jaundice is primarily prevented by initiating breastfeeding early, feeding frequently, especially during nighttime, as it stimulates the secretion of prolactin.

bubble_chart Prognosis

Breast milk jaundice generally does not cause bilirubin encephalopathy.

Therefore, breastfed jaundice in healthy newborns must be closely monitored and followed up intensively, especially for those discharged home within 2–3 days after birth. Necessary follow-ups should be established to enable early intervention and prevent brain damage.
