Dr. Zhao Xiaodong
Although iron deficiency anemia is relatively common in pregnant women, it usually does not directly cause polyhydramnios. Excessive amniotic fluid is often associated with fetal abnormalities, particularly those involving the digestive system, as well as gestational diabetes and poor blood glucose control. However, this does not mean that anemia during pregnancy can be ignored. On the contrary, severe anemia requires adequate attention. Once a pregnant woman exhibits symptoms of severe anemia, she should promptly seek medical assistance to avoid serious complications such as postpartum hemorrhage, infection, and coagulation disorders. Severe anemia may also adversely affect fetal growth and development. Therefore, pregnant women should undergo regular prenatal checkups to ensure the health of both mother and baby.
