Placental insufficiency occurs when the placenta does not provide enough oxygen and nutrients to the developing fetus. This condition can lead to growth restrictions, low birth weight, and other complications during pregnancy. It may be caused by various factors, including maternal health issues, such as high blood pressure or diabetes, and problems with the placenta itself. Symptoms of placental insufficiency can be subtle and may include decreased fetal movement or abnormal ultrasound findings. Healthcare providers monitor pregnancies for signs of this condition, and management may involve increased monitoring, early delivery, or other interventions to ensure the health of both the mother and baby.
