Which exposure is most strongly linked to placental abruption?

Which exposure is most strongly linked to placental abruption?

• A. Cocaine use
• B. Vitamin C deficiency
• C. Low protein intake
• D. Regular exercise

Answer: (A)

Placental abruption occurs when the placenta detaches from the uterine wall before delivery, and the exposure most strongly linked is cocaine use. Cocaine is a powerful vasoconstrictor that raises maternal blood pressure and narrows uteroplacental blood vessels, reducing placental perfusion and placing stress on the placental attachment. This combination of vasospasm and hypertension can trigger early detachment. Vitamin C deficiency isn’t a well-established direct risk factor for placental abruption, though it can affect connective tissue and healing. Low protein intake can influence overall fetal growth and nutrition but isn’t a known strong direct cause of abruption. Regular exercise is not associated with increased risk and is generally considered safe in pregnancy.
