The following have been identified as risk factors for placenta previa: Previous placenta previa (recurrence rate 4–8%), [13] caesarean delivery, [14] myomectomy [10] or endometrium damage caused by D&C. [13] Women who are younger than 20 are at higher risk and women older than 35 are at increasing risk as they get older.
Risk factors such as diabetes, chronic blood pressure and multiple pregnancies can increase the risk of developing placental disease. [3] Also, exposure to sudden trauma can increase the risk of placental abruption which coincides with placental disease. [6] There is no target treatment available for placental disease.
Placenta previa is a condition that occurs when the placenta fully or partially covers the cervix. [13] Placenta previa can be further categorized into complete previa, partial previa, marginal previa, and low-lying placenta, depending on the degree to which the placenta covers the internal cervical os.
Besides placenta previa and placental abruption, uterine rupture can occur, which is a very serious condition leading to internal or external bleeding. Bleeding from the fetus is rare, but may occur with two conditions called vasa previa and velamentous umbilical cord insertion where the fetal blood vessels lie near the placental insertion site unprotected by Wharton's jelly of the cord.

Risk factors include pulling on the umbilical cord or pushing on the top of the uterus before the placenta has detached. [1] Other risk factors include uterine atony, placenta previa, and connective tissue disorders. [1] Diagnosis is by seeing the inside of the uterus either in or coming out of the vagina. [2] [6]
Risk factors include smoking, pre-eclampsia, prior abruption (most important and predictive risk factor), trauma during pregnancy, cocaine use, and previous cesarean section. [2] [1] Diagnosis is based on symptoms and supported by ultrasound. [1] It is classified as a complication of pregnancy. [1]
