Neonatal jaundice is a common phenomenon in the newborn period, with 80% of full-term infants visibly exhibiting jaundice. Jaundice is divided into physiological jaundice and pathological jaundice. In full-term infants, physiological jaundice generally lasts about two weeks and ordinarily subsides within that time. For preterm infants, it typically does not last more than four weeks. However, if the jaundice progresses quickly, appears early, and is severe, reaching pathological levels, intervention and treatment are necessary. The duration of jaundice can vary depending on the baby’s condition. Without intervention, the duration of jaundice may be prolonged. Therefore, it is advisable to regularly monitor jaundice and actively intervene with treatment if abnormalities are present.
