Neonatal jaundice is one of the common symptoms during the neonatal period, especially in early newborns. It can be a symptom of the normal developmental process of newborns, or it can be a manifestation of certain diseases. Neonatal jaundice is relatively common in newborns, with about 80% of full-term infants visibly showing jaundice. Jaundice is classified into physiological jaundice and pathological jaundice. If it is pathological jaundice, there are different classifications. Based on different characteristics of bilirubin elevation, it is divided into high direct bilirubinemia and high indirect bilirubinemia. Physiological jaundice does not require intervention. However, if it is pathological jaundice, it is necessary to clarify its classification and determine which type it belongs to. Generally, if it is pathological jaundice, timely intervention and treatment are needed. If untreated, and if the jaundice level significantly increases, it may lead to serious complications.
