Women are at higher risk for placenta previa if they've had previous surgeries involving the uterus, such as:

  • A C-section
  • Surgery to remove uterine fibroids
  • Dilation and curettage, though this presents a much lower risk

Placenta previa is also more common among women who:

  • Have delivered at least one baby
  • Had placenta previa with a previous pregnancy
  • Are carrying more than one fetus
  • Are age 35 or older
  • Are of a race other than white
  • Smoke
  • Use cocaine
