Jaundice, Newborn

Jaundice is when the skin, the whites of the eyes, and mucous membranes turn a yellowish color. It is caused by increased levels of bilirubin in the blood (hyperbilirubinemia). Bilirubin is produced by the normal breakdown of red blood cells. A small amount of jaundice is normal in newborns because they have an immature liver. The liver may take 1 to 2 weeks to develop completely. Jaundice usually lasts for about 2 to 3 weeks in babies who are breastfed. Jaundice usually clears up in less than 2 weeks in babies who are formula fed.


Newborn jaundice can also be caused by:

  • Problems with the mother's blood type and the newborn's blood type not being compatible.

  • Maternal diabetes.

  • Internal bleeding of the newborn.

  • Infection.

  • Birth injuries such as bruising of the scalp or other areas of the newborn's body.

  • Prematurity.

  • Poor feeding with the newborn not getting enough calories. 


  • Yellow color to the skin, whites of eyes, or mucous membranes.

  • Poor eating.

  • Sleepiness.

  • Weak cry.


Blood tests may be taken.


Your child's caregiver will decide the necessary treatment for your newborn. Treatment may include:

  • Special light therapy (phototherapy).

  • Bilirubin level checks during follow-up exams.

  • Increased infant feedings.

  • Blood exchange (rare) if the bilirubin levels do not improve or your newborn gets worse.


  • Watch your newborn to see if the jaundice gets worse. Undress your newborn and look at his or her skin under natural sunlight by a window. The yellow color cannot be seen under artificial light.
