Yellow Skin Infant Underlying Cause
Normally, red blood cells are broken down the liver and spleen. Bilirubin is produced from the breakdown of hemoglobin, which is the molecule that carries oxygen inside red blood cells. The liver processes the bilirubin and it is removed from the body in the stool.
The most common causes of neonatal jaundice include:
- Abnormally slow breakdown of bilirubin by the liver
- Poor feeding in infants who are breast-fed
The most common causes of neonatal jaundice resolve without treatment.
