What does the term "lochia" refer to?

The term "lochia" specifically refers to the vaginal discharge that occurs after childbirth, which consists of blood, mucus, and uterine tissue. This discharge is a normal part of the postpartum period as the body sheds the remnants of the placenta and uterine lining after delivery. Lochia typically varies in color and composition over time, starting with lochia rubra, a bright red discharge that occurs in the first few days postpartum, transitioning to lochia serosa, a pinkish-brown color in the following weeks, and finally to lochia alba, a yellowish-white discharge that can last for several weeks. Understanding lochia is essential in postpartum care as it helps in monitoring the mother's recovery and spotting any potential complications that may arise, such as abnormal bleeding or infection.
