Infant Jaundice Jaundice is a common condition in newborns. Jaundice refers to the yellow color of the skin and whites of the eyes caused by excess bilirubin in the blood. Bilirubin is produced by the normal breakdown of red blood cells. Normally, bilirubin passes through the liver and is excreted as bile through the intestines. Jaundice occurs when bilirubin builds up faster than a newborn's liver can break it down and pass it from the body. There are a couple reasons why this happens. One of the reasons is because newborns produce more bilirubin than adults do, this occurs because infants have a higher turnover rate of red blood cells. Another reason is that a newborn baby's still-developing liver may not yet be able to remove adequate bilirubin from the blood. Too large of an amount of bilirubin is reabsorbed from the intestines before the baby gets rid of it in the stool. High levels of bilirubin — usually above 25 mg — can cause deafness, cerebral palsy, or other forms of brain damage in some babies. In less common cases, jaundice may indicate the presence of another condition, such as an infection or a thyroid problem. The American Academy of Pediatrics (AAP) recommends that all infants should be examined for jaundice within a few days of birth. There are a number of common types of jaundice that occur. One of the most common is Physiological (normal) jaundice. This type occurring in most newborns, this mild jaundice is due to the immaturity of the baby's liver, which leads to a slow processing of bilirubin. It generally appears at 2 to 4 days of age and disappears by 1 to 2 weeks of age. Another type is Jaundice of prematurity. This type occurs frequently in premature babies since they are even less ready to excrete bilirubin effectively. Jaundice in premature babies needs to be treated at a lower bilirubin level than in full term babies in order to
