7 months amniotic fluid depth 100mm, polyhydramnios, what is the cause

Patient's question:

No

Doctor's answer:

Review, if the amniotic fluid gradually increases, prenatal diagnosis is needed to rule out fetal urinary system abnormalities. However, a large portion of the increased amniotic fluid does not indicate fetal abnormalities, but rather high maternal blood sugar or other reasons. Therefore, it is recommended to review again.
