Breastmilk jaundice stops breastmilk for 24 hours, and the jaundice can usually be significantly reduced. Breastmilk jaundice is a condition in which a breastfed newborn remains jaundiced for 1 to 3 months after birth. The condition may be related to high levels of glucuronidase secreted in breastmilk, which causes jaundice in the baby’s intestinal tract by increasing the separation of intestinal glucuronic acid from bilirubin, allowing the reabsorption of unconjugated bilirubin by the baby’s gut, which in turn leads to jaundice in the baby. After cessation of breastfeeding, jaundice can be significantly reduced as the baby is no longer affected by the enzyme glucuronidase in breast milk and the reabsorption of unconjugated bilirubin is diminished. Apart from the yellowing of the skin, there is usually no other significant discomfort, and in a very small number of children, bilirubin encephalopathy may occur as a complication. No special treatment is needed for this disease, and breastfeeding can be continued, but if the bilirubin level in the baby reaches 20mg/dl, light treatment should be given. If breastfeeding jaundice is diagnosed, the baby should be closely monitored and if there is any special condition, it is important to go to the hospital in time and follow the doctor’s instructions for treatment.
