Hallow Dear, Placental abruption is premature separation of placenta due to which the oxygen supply and nutrition of the baby gets affected leading to foetal death. Placental abruption is always due to some cause. High blood pressure, Pregnancy induced hypertension, eclampsia, Folic acid deficiency, diabetes, trauma on the abdomen, severe anaemia, severe psychological trauma, too much or too less water around the foetus, Rh incompatibility are some of the commoner conditions which can cause placental abruption. You may get investigated for conditions like diabetes, blood pressure, blood examination, etc. before the next pregnancy. Please start Tab. Folic acid immediately for protecting the future pregnancy and the baby. Please report to your Obstetrician with a detailed history so that proper steps will be taken to evaluate you and manage accordingly. I hope this gives you initial guidance. For more detail guidance, you may ask me Direct question. Dr. Nishikant Shrotri
