Placenta Previa Condition & Symptoms

Placenta previa is a pregnancy complication that occurs when the placenta attaches to the lower wall of the uterus. The low-lying placenta may cover all or part of the cervix, and it may detach and cause dangerous bleeding as the cervix dilates in late pregnancy.

Risk Factors

Women who have an abnormal uterus or uterine scarring from previous procedures are more likely to have placenta previa. Smokers, older women and those who have been pregnant before are also at an increased risk.

Symptoms

Vaginal bleeding is the main symptom of placenta previa. Cramping is possible, but painless bleeding is common.

Treatment

Treatment commonly includes bed rest and close monitoring. Medications may be given to prevent premature labor and help the baby's lungs mature. In severe cases, the mother may be admitted to the hospital.

Complications

Severe blood loss, premature labor, shock, blood clots and infection are possible complications of placenta previa. It is sometimes necessary to deliver a baby before development is complete, according to MedlinePlus.

Outlook

With proper medical care, major complications can often be avoided. If the placenta is covering the cervix, the baby will be delivered via cesarean section, according to AmericanPregnancy.org.

Warning

Always contact your doctor if you have bleeding during pregnancy.
