Neonatal jaundice is the most common phenomenon in the neonatal period, especially in early neonates, which refers to newborns within the first week of life. About 80% of full-term infants can visually exhibit signs of jaundice. Jaundice can be categorized into physiological jaundice and pathological jaundice. Typically, physiological jaundice appears about two to three days after birth. If it is pathological jaundice, it may appear earlier, possibly within the first twenty-four hours after birth. Generally, if the jaundice appears early, progresses quickly, and is severe, it is necessary to intervene and treat promptly.
