Placental Calcification: Causes, Risk Factors & What You Need to Know

Placental calcification is calcium salt deposition in placental tissue. It's a natural, progressive process but can be exaggerated by:

1. Advanced maternal age – hormonal/vascular changes affect calcium metabolism.
2. Multiple pregnancies – cumulative uterine/placental changes.
3. Placental insufficiency – reduced blood flow (preeclampsia, hypertension, vascular disease) → ischemia → calcification.
4. Infection/inflammation – inflammatory mediators disrupt placental cells.
5. Maternal health conditions – diabetes, chronic kidney disease, autoimmune disorders.
6. Genetic factors – maternal/fetal polymorphisms linked to calcification extent.
7. Environmental factors – toxins, pollutants, medications (needs more research).

Mild late-pregnancy calcification is usually benign. Severe calcification with insufficiency may impair fetal growth, requiring close monitoring or intervention.
