What is the placenta?
The placenta is an organ that grows on the inside, upper part of your uterus (womb) when you're pregnant
It has many large blood vessels to carry oxygen and nutrients from you to the fetus (baby)
The placenta's blood vessels form the umbilical cord to connect the placenta to the fetus
About 15 minutes after you deliver your baby, the placenta comes off your uterus and goes out your vagina
That's why it's also called the "afterbirth"
What is placental abruption?
A placenta that starts to pull away from the uterus before delivery is called placental abruption. The placenta may pull away a little bit or a lot. The more that it pulls off, the more dangerous it is for you and your baby.
Placental abruption is more likely to happen after 20 weeks of pregnancy
If the placenta pulls away only a little bit, your baby might not grow as much or there might be too little amniotic fluid
If the placenta pulls away fully, your baby could die
To treat placental abruption, doctors will have you stay in the hospital and may deliver your baby early
Doctors usually don't know why placental abruption happens. However, it's more likely to happen if you:
Had placental abruption before
Have a serious injury to your abdomen (like from a car crash)
Problems With the Placenta
Normally, the placenta is located in the upper part of the uterus, firmly attached to the uterine wall until after delivery of the baby. The placenta carries oxygen and nutrients from the mother to the fetus.
In placental abruption (abruptio placentae), the placenta detaches from the uterine wall prematurely, causing the uterus to bleed and reducing the fetus’s supply of oxygen and nutrients. Women who have this complication are hospitalized, and the baby may be delivered early.
In placenta previa, the placenta is located over the cervix, in the lower part of the uterus. Placenta previa may cause painless bleeding that suddenly begins after 20 weeks of pregnancy. The bleeding may become profuse. The baby is usually delivered by cesarean.
What are the symptoms of placental abruption?
Symptoms depend on how much the placenta has pulled away from your uterus but can include:
Cramps in your belly or sudden, intense belly pain
How can doctors tell if I have placental abruption?

How do doctors treat placental abruption?
Doctors will have you stay in the hospital on bed rest so they can watch you. You may get medicine to help your baby’s lungs grow in case your baby has to be delivered early.
If your symptoms start to get better, doctors will let you walk around and may even let you go home.
Doctors will deliver your baby as soon as they can if:
You keep bleeding
Your baby's life is in danger
You’re at or more than 36 weeks along
