What causes low amniotic fluid?
Birth defects – Problems with the development of the kidneys or urinary tract which could cause little urine production, leading to low levels of amniotic fluid. Placental problems – If the placenta is not providing enough blood and nutrients to the baby, then the baby may stop recycling fluid. Leaking or rupture of membranes –This may be a gush of fluid or a slow constant trickle of fluid. This is due to a tear in the membrane. Premature rupture of membranes (PROM) can also result in low amniotic fluid levels. Post Date Pregnancy- A post date pregnancy (one that goes over 42 weeks) can have low levels of amniotic fluid, which could be a result of declining placental function. Maternal Complications- Factors such as maternal dehydration, hypertension, preeclampsia, diabetes, and chronic hypoxia can have an effect on amniotic fluid levels.
