If neonatal jaundice is physiological, the child’s mental state is relatively good, feeding is normal, growth and development are normal, and it will usually subside naturally in about 2-4 weeks. If it is not serious, it does not require special treatment. Secondly, neonatal jaundice is pathological jaundice, which depends on the specific situation. If the child has neonatal hemolytic disease, the degree of jaundice is usually more severe, and phototherapy or even blood exchange therapy should be performed in a timely manner according to the hyperbilirubinemia. If the child has neonatal jaundice due to the hepatitis virus, timely antiviral treatment and liver preservation therapy are required, and in this case the child generally has jaundice for a longer period of time, often more than 1 month or even longer.
