What is the problem of calcification during preganancy?

Hi,
Welcome to ehealthforum,
Mild calcifications are common to be seen in the placenta and are indicative of placental maturity. It does not necessarily indicate need for cesarean. If found to be of Grade 3 during earlier in pregnancy rather than third trimester, then it could be a cause for concern as it might affect nutritional and blood supply to fetus. Cesarean should be done if mother is having any underlying medical problems or heart problems, elevated blood pressure, etc. If baby is distressed or CPD is suspected, then also cesarean can be opted. She should be in regular follow-up with her treating gynecologist/obstetrician. If the scan revealed good fetal condition and no CPD, then normal vaginal delivery can be given a try (especially if she is fine and there is no contraindication for vaginal delivery and straining).
Take care.
