Which condition is a risk factor for placental abruption?

Placental abruption, which refers to the premature separation of the placenta from the uterine wall, has several well-recognized risk factors, among which hypertension disorders in pregnancy are significant. Conditions such as preeclampsia and chronic hypertension increase the risk of placental abruption due to higher pressures on the blood vessels supplying the placenta. This can lead to compromised blood flow, ultimately resulting in detachment.

Gestational diabetes and multiple gestation pregnancies, while having their own risks and complications, do not have a direct increased association with placental abruption in the same way that hypertension disorders do. Preexisting autoimmune disorders can pose risks in pregnancy, but they are not directly linked to a higher incidence of placental abruption as hypertension is.

Overall, hypertension disorders directly impact the placental structure and function, making them a critical factor in the risk for placental abruption.
