What is a potential risk associated with placenta previa?

Placenta previa is a condition in pregnancy where the placenta is located low in the uterus and can partially or completely cover the cervix. This positioning poses a significant risk of excessive bleeding, particularly during labor and delivery. When the cervix begins to dilate or efface in preparation for labor, the placenta can be disrupted or torn, leading to potentially life-threatening hemorrhage for both the mother and the baby.

The risk of excessive bleeding is a crucial concern because it can lead to complications such as shock and necessitate immediate medical interventions, including cesarean delivery to ensure the safety of both the mother and child. The management of women with placenta previa often involves careful monitoring, and in more severe cases, women may be advised to avoid strenuous activities or sexual intercourse to minimize the risk of bleeding.

While other complications, such as preterm labor, maternal hypertension, and gestational diabetes can occur in pregnancy, they are not directly associated with the anatomical risk presented by placenta previa. Thus, the increased risk of excessive bleeding during delivery is the most accurate and significant risk linked to this condition.
