Whether neonatal jaundice 11mg/dl is serious or not should be analyzed according to the age of the newborn, risk factors and other circumstances, and cannot be generalized. If the age of the newborn is 2~3 days, or accompanied by neonatal hemolysis, cephalohematoma, hypoxia, acidosis, hypoglycemia and other high-risk factors, jaundice 11mg/dl is more serious, often pathological jaundice, and need to be treated with blue light irradiation therapy, albumin, phenobarbital and other medications in a timely manner. If the newborn is more than 3 days old and does not have any of the above risk factors, jaundice 11mg/dl is not serious and generally does not require special treatment, regular testing, and the jaundice will gradually fade away as the baby grows. Therefore, newborns with jaundice 11 mg/dl should go to the hospital in time, according to the doctor’s assessment to determine the severity of the condition, under the guidance of the doctor to carry out regular treatment.
