Placental Abruption Causes
The etiology of placental abruption is often elusive to doctors. However, certain factors can heighten the risk, including:
- Previous occurrences of placental abruption. If experienced before, there’s approximately a 10% likelihood of recurrence.
- Research indicates that pre-pregnancy smoking escalates the risk of placental abruption by 40% for each year of smoking.
- Substance abuse, such as cocaine. Up to 10% of women who use cocaine during the final trimester may experience abruption.
- High blood pressure. Whether pre-existing or pregnancy-induced, managing blood pressure with your doctor is crucial.
- Amniotic sac complications. Rupture or leakage of the sac before term can raise the likelihood of abruption.
- Advanced maternal age, particularly over 35, with an increased risk seen in women over 40.
- Carrying multiple fetuses. Delivery of the first baby can trigger premature placental separation before subsequent births.
- Abdominal trauma. Accidents or falls causing abdominal injury can contribute to abruption risk. Remember to always wear a seatbelt to minimize this risk.
While placental abruption cannot be entirely prevented, avoiding tobacco, alcohol, and drugs can mitigate the chances. Informing your doctor about previous abruptions is vital for close monitoring and potential preventive measures.
