physiological jaundice of the newborn
Definition
Noun: A common, typically harmless condition in newborn infants characterized by a yellowish tint to the skin and eyes. This occurs due to the normal breakdown of fetal red blood cells and the temporary immaturity of the infant's liver, which cannot yet efficiently process the resulting bilirubin. It usually resolves on its own without medical intervention.

Advanced Usage
