Which condition is associated with increased risk of severe hyperbilirubinemia?

The association between exclusive breastfeeding as a sole nutrition source and an increased risk of severe hyperbilirubinemia is rooted in the fact that breastfeeding can sometimes lead to increased levels of bilirubin in newborns. This condition, often referred to as "breastfeeding jaundice," can occur when a baby does not receive enough breast milk in the early days after birth, leading to dehydration or insufficient caloric intake. The lack of adequate milk can impair the infant's ability to clear bilirubin efficiently through their digestive system, resulting in higher bilirubin levels and a greater risk of hyperbilirubinemia.

It's important to note that while exclusive breastfeeding is generally promoted for its numerous health benefits, it is crucial for new mothers to be educated on proper feeding techniques and to ensure that the infant is feeding often and effectively in the early days. Understanding this relationship helps caregivers take proactive measures in monitoring jaundice levels in breastfed infants and intervening as necessary.

Other conditions listed in the choices do not have a direct correlation with an increased risk of severe hyperbilirubinemia like breastfeeding does. Low bilirubin levels in siblings, higher gestational age, and lower incidence of cephalohematoma do not reflect the same risks associated with breastfeeding practices and their potential
