What is a common risk associated with placenta previa during the later weeks of pregnancy?

Vaginal bleeding is a common risk associated with placenta previa, particularly in the later weeks of pregnancy. In this condition, the placenta is abnormally positioned at or near the cervix, which can lead to bleeding as the cervix starts to efface and dilate closer to term. This bleeding can occur spontaneously and may vary in amount, being light or heavy, which poses significant risks to both the mother and the baby. If significant bleeding occurs, it may necessitate hospitalization and could lead to preterm delivery if it compromises the mother's or baby's health.

While gestational diabetes, high blood pressure, and fetal growth restriction can occur in pregnancy and may have other associations, they are not directly linked to placenta previa in the same manner as vaginal bleeding. Understanding the specific risks of placenta previa is crucial for monitoring and managing the health of both the mother and the fetus throughout the pregnancy.
