Sometimes the cause it not clear. Other times it may be due to:
- Rupture of an artery or vein in the uterus which causes bleeding between the placenta and the uterine wall
- Problems with how the placenta forms
- Low oxygen levels in the uterus
- Injury to the belly from an accident or a fall
- Sudden decrease in the volume of the uterus, from losing amniotic fluid or from the delivery of a first twin
This health problem is more common in older mothers.
Factors that may raise your risk are:
- Prior abruption
- Multiple prior deliveries
- Smoking during pregnancy
- Drug misuse , especially cocaine
- Vaginal bleeding during pregnancy
- High blood pressure during pregnancy
- Being pregnant with multiples
- Prior cesarean section (C-section)
Talk with your doctor about the best plan for you. You may have:
Fluids may be given by IV to replace lost fluids. Blood transfusions may also be given to replace lost blood supply.
You and your fetus will be carefully monitored for signs of distress or shock .
Emergency Cesarean Delivery
If you or your fetus are in danger, an emergency cesarean section will be done. If you and your fetus are at low risk of problems and your fetus is full-term, then you may deliver vaginally .
