Jaundiced Newborn

Jaundice and Bilirubin

  • Jaundice means the skin has turned yellow.
  • Bilirubin is the pigment that turns the skin yellow.
  • Bilirubin comes from the normal breakdown of old red blood cells.
  • The liver normally gets rid of bilirubin. But, at birth, the liver may be immature.
  • Half of babies have some jaundice. Usually it is mild.
  • The level of bilirubin that is harmful is around 20. Reaching a level this high is rare.
  • High levels need to be treated with bili-lights. That's why your doctor checks your baby's bilirubin levels until it becomes low.

  • Peaks day 4 to 5, then improves

Breastfeeding or Malnutrition Jaundice (5 to 10% of newborns)

  • Due to inadequate intake of breastmilk
  • Onset pattern similar to physiological type
  • Also, causes poor weight gain

Breastmilk Jaundice (10% of newborns)
