Calcification of the placenta occurs when certain blood vessels in the placenta become blocked for a long period of time, resulting in ischemic necrosis of the placental tissue with calcium deposits at the site of necrosis. Calcification of the placenta is commonly referred to as aging of the placenta. When the fetus matures at the end of pregnancy, the placenta’s role in nurturing a new life will be over, so it will naturally age like any other organ, which is a normal phenomenon. However, if placental calcification occurs early, or if the placenta is highly graded and accompanied by a decrease in amniotic fluid, it may affect the function of the placenta and cause the fetus to function without oxygen. Placental calcification usually does not require treatment, but only in serious cases such as vaginal bleeding, decreased fetal movement, and serious complications such as neonatal asphyxia, aspiration pneumonia, and fetal distress, it is recommended to consult a doctor promptly.
