What are the causes of placenta aging?

If placental aging occurs before the expected date of delivery, this is a normal manifestation. This is the natural aging of the placenta. If the pregnant woman does not reach the expected date of delivery, this symptom may be caused by malnutrition in pregnant women, or by the stimulation of diseases such as hypertension and diabetes in pregnant women. Suggestions: pregnant women need to go to the hospital regularly for prenatal check-ups to determine the growth of the mother and fetus.
