Patient's question:
The baby has been born for a week now, and recently the baby's skin has turned particularly yellow, and even the face is a bit yellow. Some elders said this is physiological jaundice. Could you please tell me what are the characteristics of physiological jaundice in newborns?Doctor's answer:
Neonatal physiological jaundice: 1 case. Good mental response and sleep.2. Full-term infants develop jaundice 2-3 days after birth, peak at 4-5 days, and resolve by 5-7 days, not exceeding 2 weeks. Preterm infants develop jaundice after 3-5 days of birth, peak at 5-7 days, and resolve by 7-9 days.
3. Serum bilirubin levels increase by less than 85 umol/L or 8.5 umol/L/h daily.
4. Bilirubin levels are assessed based on age or time.
Physiological jaundice has always been a specific diagnosis. Determining whether it is physiological or pathological is influenced by individual differences, race, region, genetics, and other factors, with no unified standard established to date.
