Early neonatal jaundice

Early neonatal jaundice is a common, often self-limiting condition in newborns resulting from high bilirubin levels, most frequently appearing after the first 24 hours of life.

It is caused by a combination of higher red blood cell breakdown, shorter red blood cell lifespan, and an immature liver's inability to process bilirubin efficiently. The key is distinguishing between benign physiologic jaundice and more serious pathologic jaundice through clinical evaluation and monitoring bilirubin levels.
