List 7 possible causes of neonatal jaundice?

1. Physiological jaundice: This is the most common cause of neonatal jaundice and occurs in approximately 60% of full-term newborns and 80% of preterm newborns. It is caused by the immature liver's inability to efficiently process bilirubin, resulting in a buildup of the substance in the blood.

2. Breastfeeding jaundice: This type of jaundice occurs in breastfed newborns and is often due to inadequate milk intake, leading to dehydration and reduced bilirubin excretion.

3. Breast milk jaundice: This type of jaundice is caused by a substance in breast milk that inhibits the breakdown of bilirubin in the liver, leading to elevated levels of bilirubin in the blood.

4. Blood group incompatibility: If a mother and baby have incompatible blood types (such as Rh incompatibility or ABO incompatibility), the mother's antibodies can attack the baby's red blood cells, leading to an increase in bilirubin levels.

5. Hemolytic disease of the newborn: This condition occurs when the baby's red blood cells are destroyed at a faster rate than they can be replaced, leading to an increase in bilirubin levels.

6. Infections: Certain infections, such as sepsis or urinary tract infections, can cause neonatal jaundice by increasing the breakdown of red blood cells and impairing the liver's ability to process bilirubin.

7. Genetic disorders: Rare genetic disorders, such as Gilbert syndrome or Crigler-Najjar syndrome, can cause neonatal jaundice by impairing the liver's ability to process bilirubin.
