Answer
Jaundice can be classified into physiological jaundice and pathological jaundice. Physiological jaundice usually appears 2 to 3 days after birth, reaches its peak between 4 and 6 days, and resolves within 10 to 14 days in full-term infants, or up to 3 to 4 weeks in premature infants. Generally, no special treatment is required as it is due to the large-scale destruction of red blood cells after birth, excessive production of bilirubin, and underdeveloped liver function leading to low bilirubin decomposition and metabolism capabilities. Pathological jaundice includes early onset (within 24 hours after birth), severe levels, prolonged duration, or recurrence after jaundice subsides. It is recommended to use blue light therapy for treatment.
