Finding out you are going to have a baby brings so much joy, but it can also bring a few worries. You might wonder about every little change in your body. When you are pregnant, your placenta plays a vital role in feeding your growing baby. Sometimes, however, the placenta attaches too deeply into the wall of the uterus. This condition is called placenta accreta, and it requires careful medical attention.
Understanding this condition can help you feel more prepared and less afraid. Doctors and nurses are ready to guide you through every step of your prenatal care. Let us explore what placenta accreta is, why it happens, and how your medical team will keep you and your baby safe.
Key Takeaways About Placenta Accreta.
- Placenta accreta happens when the placenta grows too deeply into the uterine wall.
- Previous C-sections or uterine surgeries are the most common risk factors.
- Early ultrasound scans help doctors catch this condition before delivery day.

What Is Placenta Accreta?
In simple terms, placenta accreta is a pregnancy condition where the placenta attaches far too deeply into the wall of the womb. During a healthy pregnancy, the placenta delivers oxygen and food to your baby through the umbilical cord. After your baby is born, the placenta naturally peels away from the uterine wall.
With placenta accreta, the placenta does not peel away easily after birth because it is stuck tight. Think of planting a tree in your garden. Normally, the roots spread smoothly through the soft soil. But with placenta accreta, those roots grow far too deep, wrapping tightly around the muscle layers of the womb like tough concrete.
In severe cases, this strong attachment can cause heavy bleeding from the vagina. This heavy bleeding can become a serious medical emergency. Doctors often manage this by planning an early C-section delivery followed by surgery to remove the uterus, which is called a hysterectomy. Finding this condition early during prenatal care helps your medical team protect you from dangerous complications.
Types of Placenta Accreta.
There are three main types of placenta accreta. Doctors figure out which type you have by checking how deeply the placenta has grown into your uterine wall.
1. Placenta Accreta (Standard): This is the most common type. The placenta attaches firmly to the muscle wall of the uterus, but it does not grow into the muscle itself.
2. Placenta Increta: In this type, the placenta grows even deeper into the muscular wall of the uterus. It grips tightly to the muscle layers, making it much harder to remove after birth.
3. Placenta Percreta: This is the most severe and dangerous type. The placenta grows completely through the uterine wall and can attach to nearby organs like your bladder or bowel.
Who Has a Higher Risk of Placenta Accreta?
Certain factors can raise your chances of developing placenta accreta during pregnancy. You might have a higher risk if:
- You have had previous C-section deliveries, especially multiple surgeries.
- Your placenta is sitting low in your uterus, covering your cervix, which is known as placenta previa.
- You have had past surgeries on your uterus, such as fibroid removal or dilation and curettage procedures.
- You have had multiple previous pregnancies.
- You conceived using in vitro fertilization (IVF).
Imagine your friend, let us call her Sarah, has already delivered two babies via C-section. Now she is pregnant with her third child, and her doctor tells her to watch her placental placement closely. Because past C-sections leave tiny scars on the womb, those scar tissues create spots where the placenta can attach too deeply.
Does Placenta Accreta Harm Your Baby?
Placenta accreta does not directly harm your baby inside the womb. However, the condition often leads to early birth, also known as a preterm birth. This means your baby might arrive before 37 weeks of pregnancy.
Babies born early may face breathing trouble or low birth weight. They might also need extra care in the neonatal intensive care unit (NICU) for a short time after birth.
Risks for the Mother.
Hearing about these risks can feel scary, but knowing them helps you stay informed. An expectant mother with placenta accreta may face risks such as:
- Early labor and delivery.
- Damage to the uterus and nearby organs like the bladder or bowels.
- Loss of future fertility if the uterus must be removed.
- Heavy blood loss requiring blood transfusions.
- Blood clotting problems.
- Temporary kidney or lung strain.
- In rare cases, life-threatening complications.
How Common Is Placenta Accreta?
Placenta accreta affects roughly 1 out of every 533 pregnancies. However, the number of diagnosed cases has increased over the past few decades. The main reason for this rise is the higher number of C-section deliveries performed worldwide.
Causes of Placenta Accreta.
The primary cause of placenta accreta is an abnormality in the inner lining of the uterus, often due to prior scarring from surgery. However, some women with no previous uterine surgeries can still develop the condition.
Key risk factors and causes include:
- Previous C-sections: Having multiple C-sections raises your risk greatly because scar tissue invites abnormal attachment. More C-sections mean higher risk. Over 60% of placenta accreta cases happen in women with past C-sections.
- Uterine surgeries: Removing noncancerous uterine fibroids or having a D&C procedure can leave scars that lead to this condition.
- Low-lying placenta: When the placenta covers the cervix, combined with prior C-sections, the risk multiplies.
Symptoms of Placenta Accreta.
Many women with placenta accreta have no symptoms at all. That is what makes routine prenatal visits so vital. However, some mothers experience light or heavy vaginal bleeding during the third trimester, or lower belly pain due to the placenta pressing against nearby organs.
How Doctors Diagnose Placenta Accreta.
Doctors can often spot placenta accreta during a routine ultrasound scan in your second or third trimester. Sometimes, doctors order a Magnetic Resonance Imaging (MRI) scan to see exactly how deep the placenta has grown.
In other cases, doctors discover placenta accreta only after the baby is born. Normally, the uterus squeezes and pushes out the placenta within 30 minutes after delivery. If the placenta refuses to detach, your doctor will right away suspect placenta accreta.
Why Early Diagnosis Matters.
Finding placenta accreta early during your pregnancy is absolutely vital for your safety.
An early diagnosis lets a team of specialists plan your care together. This team may include a high-risk pregnancy specialist, a surgeon, and a neonatal doctor for your baby. Your doctor will watch you closely to ensure the best possible outcome.
Working with the right medical team helps reduce severe blood loss and may even help preserve your uterus. While severe cases still require surgery and blood transfusions, catching the condition early lowers overall risks.
Treatment Options for Placenta Accreta.
Treatment plans vary based on your specific health needs. If your doctor finds placenta accreta early, they will monitor you closely. They might suggest bed rest at home or a hospital stay to prevent early labor.
Your doctor will schedule a C-section delivery, usually between 34 and 37 weeks of pregnancy. This planned timing prevents labor contractions that could cause dangerous bleeding. If you wish to have more children in the future, your doctor will try every safe method to protect your uterus.
However, in severe cases where the placenta grows deep into the muscle or nearby organs, a hysterectomy is the safest choice. A cesarean hysterectomy removes the baby first and then removes the uterus with the placenta still attached. This stops heavy bleeding and protects your health.
In very rare instances, doctors leave small pieces of the placenta inside the body to dissolve naturally over time. This approach carries high risks of severe bleeding, infection, and blood clots, so doctors only use it in specific situations.
When Will Your Baby Be Delivered?
Most doctors recommend scheduling a C-section between 34 and 37 weeks of pregnancy if there are no other complications. This timing stops labor contractions from starting naturally, which keeps bleeding under control. Your doctor may also give you corticosteroid shots to help your baby's lungs develop faster before delivery.
Can You Prevent Placenta Accreta?
You cannot completely prevent placenta accreta. However, understanding your medical history and risk factors helps you and your doctor prepare. Talk openly with your obstetrician about your past surgeries and pregnancy history.
What Does the Future Hold?
When doctors diagnose placenta accreta before birth, outcomes are usually positive. However, managing early birth and possible hysterectomy requires careful recovery. If you need a hysterectomy, you will not be able to get pregnant again. With proper medical care, most mothers recover fully and return to healthy lives.
Can You Have Another Baby After Placenta Accreta?
Your ability to have another baby depends entirely on whether you had a hysterectomy. If you wish to grow your family in the future, discuss your plans with your doctor early so they can explore options that protect your fertility whenever possible.
Survival Rates and Outlook.
Survival rates for placenta accreta are generally high when managed by an experienced surgical team. Planned deliveries and prompt treatment of postpartum bleeding keep mothers safe and healthy.
When Should You Call Your Doctor?
Placenta accreta is a high-risk pregnancy condition. Follow all guidance from your medical team. If you notice warning signs, reach out to your doctor right away.
🚨 Emergency Red Flags.
If you experience heavy vaginal bleeding (soaking through a sanitary pad in less than an hour) or severe lower belly pain, call 911 (US/Canada) or 999 (UK) right away, or go straight to the nearest hospital Emergency Department.
Questions to Ask Your OB-GYN.
Discovering you have placenta accreta brings up many questions. Here are some helpful questions to ask your doctor during your next visit:
- Will my baby need to be delivered early?
- What specific treatment plan do you recommend for me?
- Do I need bed rest or activity limits at home?
- How will I know when it is time to go to the hospital?
- Can I attempt a vaginal delivery, or do I need a C-section?
- Will I need a hysterectomy during delivery?
- Can I have more children in the future?
| Condition Aspect. | Standard Pregnancy. / Placenta Accreta. |
