A member asked:

What causes polyhydramnios in gdm?

A doctor has provided 1 answer
Dr. Nikolaos Zacharias answered

Specializes in Maternal-Fetal Medicine

Fetal polyuria.: When the maternal blood sugar is elevated for prolonged periods of time, the sugar crosses over to the fetus and it cannot retain it in its kidneys, therefore profuse fetal glucosuria ensues. This leads to polyhydramnios.
