Final answer:
Physiologic engorgement is a normal occurrence in breastfeeding when the milk supply increases, while pathologic engorgement is a more severe and prolonged condition that can occur when breastfeeding is abruptly stopped.
Step-by-step explanation:
Physiologic engorgement is a normal occurrence in the breast tissue when a person first starts breastfeeding or when the milk supply increases. It is characterized by swelling, tenderness, and leakage of milk.
On the other hand, pathologic engorgement refers to a more severe and prolonged breast engorgement that can occur when breastfeeding is abruptly stopped. It can lead to discomfort, pain, and potential complications such as mastitis.
