Introduction
Jaundice typically appears in infants 2 to 3 days after birth. A bilirubin level not exceeding 12 mg/dL is considered normal for full-term newborns, while for preterm infants, a level not exceeding 15 mg/dL is considered normal. Normally, full-term infants develop jaundice 2 to 3 days after birth, with the peak occurring at 4 to 6 days, and the jaundice gradually subsides between 7 and 10 days.
Jaundice typically appears in infants 2 to 3 days after birth. A bilirubin level not exceeding 12 mg/dL is considered normal for full-term newborns, while a level not exceeding 15 mg/dL is considered normal for premature infants. Specifically:
Under normal circumstances, full-term infants develop jaundice 2 to 3 days after birth, with bilirubin levels peaking between days 4 and 6, and the jaundice gradually subsiding by days 7 to 10. Premature infants tend to have a longer duration of jaundice, which is usually accompanied only by mild poor appetite and no other clinical symptoms. If jaundice persists for an extended period, worsens progressively, or reappears after fading, it is considered pathological jaundice.
In full-term infants, peak bilirubin levels range from 10 to 12 mg/dL before gradually decreasing. In premature infants, bilirubin levels should not exceed 15 mg/dL and will subsequently decline gradually. In cases of pathological jaundice, bilirubin levels may rise daily, exceeding 12 mg/dL in full-term infants and 15 mg/dL in premature infants.
Patients are advised to seek timely medical attention when experiencing any discomfort and to receive standardized treatment under a doctor's guidance, which helps promote recovery.
