Is Newborn Jaundice Innate?

Newborn jaundice refers to a condition characterized by yellowish discoloration of the skin, mucous membranes, and sclera during the neonatal period, categorized into physiological jaundice and pathological jaundice. It is caused by the accumulation of bilirubin in the body, leading to elevated levels of blood bilirubin. Physiological jaundice in full-term infants usually occurs 2-3 days after birth, reaches its peak at 4-5 days, and resolves between 5-7 days, with the latest not exceeding 2 weeks. Premature infants may experience a longer duration.
