Whereas breastfeeding jaundice is a mechanical problem, breast milk jaundice is a biochemical occurrence and the higher bilirubin possibly acts as an antioxidant. Breast milk jaundice occurs later in the newborn period, with the bilirubin level usually peaking in the sixth to 14th days of life.
Breast milk jaundice is caused by an increased concentration of β-glucuronidase in breast milk, which increases bilirubin deconjugation and reabsorption of bilirubin, leading to persistence of physiologic jaundice with unconjugated hyperbilirubinemia. Onset of breast milk jaundice is within 2 weeks after birth and lasts for 4–13 weeks.
In undiagnosed and untreated children, the accumulation of precursor metabolites due to the deficient activity of galactose 1-phosphate uridylyltransferase (GALT) can lead to feeding problems, failure to thrive, liver damage, bleeding, and infections. The first presenting symptom in an infant is often prolonged jaundice.
The mature breast milk is rich in fat and higher in calories to help babies grow." Wright says that as time goes on, the nutrients in breast milk continue to benefit a child, though the benefits ...
This allows a diagnosis to be made while the person is still an infant. Affected children can have serious, irreversible effects or even die within days from birth. Infants affected by galactosemia typically present with symptoms of lethargy, vomiting, diarrhea, failure to thrive, and jaundice.
Crigler–Najjar syndrome is a rare inherited disorder affecting the metabolism of bilirubin, a chemical formed from the breakdown of the heme in red blood cells. The disorder results in a form of nonhemolytic jaundice, which results in high levels of unconjugated bilirubin and often leads to brain damage in infants.

The causes of breast milk jaundice include variations in bilirubin metabolism, genetic variations, and variations in breastmilk, including the harmless and helpful germs found naturally on the surface of the skin and in the breastmilk. [40] Breast milk jaundice is usually not a reason to stop nursing. [121]
