Breast milk jaundice refers to the jaundice that occurs 4-7 days after birth in breastfed infants, and it can subside by itself after 4-11 weeks; if breastfeeding is suspended, the jaundice will mostly decrease rapidly within 2-4 days. Breastmilk jaundice is caused by excessive activity of glucuronidase in breastmilk, which increases the reabsorption of bilirubin in the intestinal tract. The peak of jaundice occurs in the 2nd-3rd week, and the growth, development, and intellectual status can be the same as that of healthy infants. If breastfeeding is suspended for 2-3 days, the jaundice may subside significantly, but the jaundice may reappear after resumption of breastfeeding. Therefore, stopping breastfeeding is generally not recommended, but if the jaundice value is very high, it is still recommended to suspend breastfeeding for 3-5 days. Suggest mothers pay attention to diet, infants and young children can take probiotics, or under the guidance of the doctor take Yin gardenia yellow, promote the excretion of bilirubin, relieve the symptoms of jaundice. Breast milk jaundice without special treatment, parents need to pay attention to indoor light enough, when appropriate, can let the child sunshine, because the blue light in the sunshine has obvious efficacy to reduce yellow. However, the premise of diagnosing breast milk jaundice is to exclude pathological jaundice, so as to avoid delaying the treatment and aggravating the condition.
