Which statement about the use of low-dose aspirin for preeclampsia prevention is correct?

The use of low-dose aspirin for the prevention of preeclampsia has specific guidelines regarding its timing of initiation during pregnancy. The correct statement highlights that low-dose aspirin should be started before 12 to 16 weeks of gestation to be effective. This is crucial because the earliest stages of pregnancy are when the placental development and uterine adaptations happen. Early administration of low-dose aspirin can help in promoting better placental blood flow and may reduce the risk of developing preeclampsia, particularly in women at high risk.

Starting low-dose aspirin too late in pregnancy may not provide the protective effects necessary to mitigate the risk of preeclampsia or its associated complications. Therefore, proper timing is essential for the effectiveness of the intervention in preventing this serious condition.
