Neonatal jaundice can occur in about half of full-term infants and is relatively common. Most children have physiological jaundice, which means that the value of jaundice is not particularly high, and the child is generally in good condition and needs to be closely observed without special medication. However, if the jaundice is obvious, the child needs to go to the hospital and the doctor will look for the cause of the jaundice and give treatment for the cause. Parents should not apply the so-called anti-yellowing drugs on their own, such as gardenia yellow granules and probiotics to help reduce the yellowing treatment. If the jaundice reaches a value that requires intervention, anti-yellowness treatment is given, such as blue light irradiation and blood exchange therapy. Immunoglobulin and albumin are needed if the jaundice is hemolytic.
