What risk is associated with the use of aspirin during pregnancy?

The use of aspirin during pregnancy is associated with an increased risk of bleeding during delivery. Aspirin is an antiplatelet agent, meaning it inhibits platelet aggregation, which can lead to a prolonged bleeding time. This is particularly concerning during labor and delivery when the risk of hemorrhage increases. The potential for bleeding complications can pose serious risks to both the mother and the infant during the delivery process, as well as for postpartum recovery.

In contrast to this, the other options do not accurately reflect the specific risks associated with aspirin use during pregnancy. While some medications may be linked to hypertension or gestational diabetes, aspirin itself is not typically associated with those conditions. The link between aspirin and birth defects is minimal, especially when compared to known teratogenic medications. Therefore, the most pertinent concern with aspirin during pregnancy revolves around its effect on bleeding tendencies during delivery.
