Who is most at risk for oligohydramnios?

Honor Society of Nursing (STTI)

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.

Pregnancy Complications

Complications can fall into the category that is harmful to the baby and/or harmful to the mother. Many women develop gestational diabetes, which only affects the mother. Preeclampsia, which elevates the blood pressure of the mother during pregnancy, can be harmful to both mother and baby. Ectopic pregnancies can put both the mother and baby at risk when the embryo attaches to the fallopian tube, instead of moving to the uterus. Miscarriages or premature births can also happen to pregnant women with certain risk factors. When going through labor, progress can slow, causing distress for the baby and mother. In some cases, a C-section is needed to keep from causing harm to both the baby and mother.
