How long does physiological jaundice in newborns usually last?

Patient's question:

My daughter is seven days old, and her jaundice hasn't gone down yet. How long does physiological jaundice usually last in newborns?

Doctor's answer:

If it is found that the child has jaundice, parents do not need to worry too much, and timely treatment is not a problem. Jaundice is divided into physiological jaundice, which appears 2-3 days after birth, peaks between 4-6 days, and disappears within 7-10 days. Premature infants have a longer duration, with only mild loss of appetite as the only clinical symptom. If jaundice occurs within 24 hours after birth and does not disappear within 2-3 weeks, even deepens or recurs after fading, or if jaundice only begins 1 week to several weeks after birth, these are all pathological jaundice. For physiological jaundice, it is recommended to start breastfeeding as soon as possible. For pathological jaundice, it is recommended to go to the hospital for phototherapy or traditional Chinese medicine treatment.
