Introduction
Early-onset neonatal jaundice can be classified as either pathological or physiological. Here, we focus primarily on the causes of pathological jaundice. The most common causes include congenital biliary tract abnormalities, sepsis, and ABO hemolytic disease. Pathological jaundice arises under specific circumstances that disrupt bilirubin metabolism in infants.
Yellowing of the skin on a newborn’s face is strongly associated with neonatal jaundice. From a pathological perspective, the severity of neonatal jaundice varies. Pathological neonatal jaundice is comparatively more serious. So, what is the most common cause of pathological neonatal jaundice?
Most Common Causes of Pathological Neonatal Jaundice
In early neonates, jaundice can be classified as either physiological or pathological. Here, we focus specifically on the causes of pathological jaundice. The most common causes include congenital biliary tract abnormalities in infants, sepsis, and ABO hemolytic disease. These conditions arise under specific circumstances—such as maternal use of excessive medications or blood type incompatibility between parents—which disrupt bilirubin metabolism in the infant and thereby trigger pathological jaundice.
It is normal for jaundice to appear within the first 24 hours after birth; however, if it recurs repeatedly, parents should promptly take the infant to a hospital for evaluation. As jaundice progresses, the risk of infection increases, and the infant may exhibit symptoms including lethargy, dull or vacant gaze, persistent crying and irritability, excessive sleepiness, constant anxiety or fear, and difficulty sucking. In advanced stages, generalized jaundice develops, and serum bilirubin levels exceed 2 mg/dL.
Prevention of pathological jaundice begins during pregnancy. Expectant mothers should practice dietary caution—avoiding unhygienic or unhealthy foods—to reduce risks of viral or parasitic infections that could affect the developing fetus. Regular physical exercise early in pregnancy helps strengthen maternal immunity and reduces susceptibility to infections. Adequate intake of vitamins and high-protein nutritional supplements is also recommended. Frequent prenatal check-ups are essential, along with maintaining emotional stability and practicing exclusive breastfeeding. Additionally, screening for parental blood type incompatibility (e.g., ABO or Rh incompatibility) is crucial for preventing hemolytic disease-related jaundice.
