Patient's question:
Nowadays, more and more newborns are experiencing physiological jaundice. Recently, my friend's child was diagnosed with physiological jaundice shortly after birth, and I'm quite worried about the child. Generally, how much is physiological jaundice in newborns?Doctor's answer:
Due to the metabolic characteristics of bilirubin in newborns, approximately 50%-60% of full-term infants and 80% of preterm infants will develop physiological jaundice, generally in good condition. Jaundice typically occurs 2-3 days after birth, with the peak appearing on days 4-5, and usually subsiding between 5-7 days, but not later than 2 weeks. In preterm infants, jaundice occurs 3-5 days after birth, peaks between 5-7 days, and resolves between 7-9 days. The increase in serum bilirubin is less than 85μmol/L, or 5mg/dL per day, and should not be delayed beyond 3-4 weeks. As long as it is within the normal range, it is physiological. If it is relatively high, it may be pathological. The hospital needs to further confirm and examine it.
