High bilirubin levels in newborns are usually caused by excessive production and accumulation of bilirubin in the body, or due to immature liver function or incomplete biliary tract function in newborns. Therefore, prompt treatment should be sought when symptoms of high neonatal jaundice appear. Treatment for high bilirubin levels in newborns generally involves phototherapy with blue light; in some cases, blood exchange transfusion may also be necessary.
