Hearing a strange term like placenta calcification can be scary and nerve-wracking. But as long as it is monitored, your baby should be fine. The term refers to calcium deposits that appear on the placenta as the placenta ages towards the end of the pregnancy.

  • These deposits of calcium can cause certain small parts of the placenta to die and some parts of the placenta to be replaced with fibrous tissue. The calcium deposits can also obstruct parts of the placenta with blood clots. Your blood vessels could also be affected or blocked by the deposits.
  • In most cases, placental calcification does not affect placenta’s ability to do its job, and the foetus is generally not harmed.
  • When calcification is found early on in the pregnancy, it can be an indication that the placenta is ageing faster than it should. If this occurs, your doctor will monitor your baby at regular intervals to make sure that he is receiving the nutritional content that he needs, and that his nutritional intake is not obstructed by the calcium deposits.
  • Some studies suggest that placental calcification can be caused by cigarette smoking.
