Anterior placenta: what it means, diagnosis and complications (2023)


What is an anterior placenta?

An anterior placenta means your placenta is at the front of the uterus, closer to the abdomen. It is common during pregnancy and is not usually a cause for concern. It is diagnosed during an ultrasound at 18-21 weeks of pregnancy.

Your placenta forms where a fertilized egg implants in the wall of the uterus. It transports nutrients, hormones and oxygen from you to your babythe umbilical cord. It also removes your baby's waste. The placenta usually grows at the back or top of the uterus, but in the case of an anterior placenta, the placenta grows at the front of the uterus. Think of an anterior placenta as a pillow between your tummy and your baby.

The placenta can move as your belly grows, meaning your placenta may start at the front but may move toward the top of the uterus as your pregnancy progresses. An anterior placenta does not cause any health problems for you or your baby. In most cases, you will not notice any effects of an anterior placenta.

Why do some people have an anterior placenta?

It is not known why a fertilized egg implants in the front part of the uterus as opposed to other places in the uterus. The front wall of the uterus is still a normal site for egg implantation and placenta development. It does not interfere with the placenta's ability to deliver nutrients to your baby.

How common is an anterior placenta?

An anterior placenta is common. The placenta is in front of the uterus in up to 50% of all pregnancies. One study showed that anterior placentas appear to be more common in people with o-positive blood. Another found that sleeping on your stomach during conception might have something to do with the fertilized egg implanting itself in the front of the body. More scientific evidence is needed to confirm these studies.

What is the difference between anterior and posterior placenta?

The placenta grows inside the uterus at the implantation site (where the fertilized egg cell attaches to the uterine wall). There are several places where a placenta can form during pregnancy:

symptoms and causes

What are the symptoms of an anterior placenta?

An anterior placenta does not cause many symptoms and is not a cause for concern most of the time. Some noticeable signs of an anterior placenta are:

  • heart rate of the baby: It may take longer for your doctor to detect your baby's heartbeat with a Doppler ultrasound. The Doppler is moved in your abdomen to measure the baby's heart rate. It may take longer because the placenta is between the baby and the doppler.
  • Baby move: You may feel kicks or punches later than people with a rear placenta. Most people feel kicks around 18 weeks of pregnancy, but people with an anterior placenta may not feel kicks until after 20 weeks. They may also feel weaker or softer because the placenta acts as a barrier between the baby and the tummy.
