Does Gestational Diabetes Cause Oligohydramnios?

Oligohydramnios and polyhydramnios were found to be associated with diabetes mellitus patients (P = 0.005), and polyhydramnios with gestational diabetes patients (P = 0.052). Other maternal chronic diseases showed no effect on amniotic fluid index, although it might cause other risks on the fetus.

Can gestational diabetes cause low amniotic fluid?

Maternal hypertension, preeclampsia and gestational diabetes are also known to contribute to low amniotic fluid.

What is the most common cause of Oligohydramnios?

Rupture of the membranes is the most common cause of oligohydramnios. However, because the amniotic fluid is primarily fetal urine in the latter half of the pregnancy, the absence of fetal urine production or a blockage in the fetus's urinary tract can also result in oligohydramnios.
