Who is most at risk for oligohydramnios?

Women most at risk for oligohydramnios include:
  • Those whose pregnancy lasts at least 42 weeks (post-term pregnancy);
  • Those at risk for a tear in the amniotic sac due to infections, poor nutrition, smoking during pregnancy, previous cervical surgery, or previous membrane tears;
  • Those diagnosed with a chronic disease such as diabetes, high blood pressure, or lupus (in which the immune system attacks healthy tissue); or
  • Those being treated for a life-threatening heart condition in the second or third trimesters with angiotensin-converting enzyme (ACE) inhibitor medication.
Because oligohydramnios can also be caused by a poorly-developed fetus, women with a family history of certain genetic disorders or women whose uterus size does not match her pregnancy stage are also at risk.
