Causes and Risks of Low Amniotic Fluid

9. Maternal Conditions

An expectant mother with chronic high blood pressure is at risk for low amniotic fluid. Risk increases if the mother takes certain blood pressure medications. Other conditions that may cause low amniotic fluid are diabetes, hypoxia, dehydration, and preeclampsia. Early in pregnancy, severe morning sickness may cause the condition. Sometimes morning sickness extends into the second trimester and further into the day. An OG-Gyn may recommend bed rest with IV fluids to treat low amniotic fluid due to excessive nausea and vomiting.
