Placenta previa

Placenta previa is a condition in pregnancy where the placenta attaches itself in the lower part of the uterus near to or over the cervix. This condition can cause severe bleeding during pregnancy and delivery. Placenta previa is usually diagnosed during the third trimester of pregnancy.

Causes

The exact cause of placenta previa is unknown. However, some factors may increase the risk of developing this condition. These include a history of cesarean section, multiple pregnancies, and being of an older maternal age.

Symptoms

The main symptom of placenta previa is painless bleeding during the third trimester. Other symptoms may include premature contractions and baby being in a breech position.

Diagnosis

Placenta previa is usually diagnosed through an ultrasound during the second trimester. If placenta previa is suspected, a follow-up ultrasound may be done in the third trimester to confirm the diagnosis.

Treatment

Treatment for placenta previa depends on the severity of the condition, the gestational age, and the health of the mother and baby. Treatment options may include bed rest, medication to stop premature labor, and delivery by cesarean section.

Complications

Complications of placenta previa can include severe bleeding, premature birth, and baby being in a breech position. In some cases, a hysterectomy may be needed to control bleeding.

Prevention

There is no known way to prevent placenta previa. However, regular prenatal care can help detect the condition early and manage any complications.
