Placenta Retention After Childbirth: Causes, Symptoms, and Treatment in Detail

The placenta is crucial during pregnancy, but it must be removed soon after birth. If it does not resolve on its own, it can cause serious problems. This article explains what happens if the placenta is not removed after birth, the associated risks, and the treatments that can help.

Placenta
Bringing a baby into the world is a special moment, but recovery involves necessary steps your body must complete. One key process is the removal of the placenta after childbirth. If the placenta does not come out on its own, it is important to understand what can happen next. Here’s a straightforward explanation.

Understanding the Placenta

  • The placenta develops during pregnancy and supplies the baby with oxygen and nutrients.
  • It also removes waste products from the baby’s blood.
  • After childbirth, the placenta is no longer required and should detach from the womb naturally.
  • This stage is known as the third stage of labour.
Usually, the placenta is delivered within 15 to 30 minutes. Sometimes it may not separate or remain stuck. This is called a retained placenta.

Types of Retained Placenta

There are three main types you should know:
Placenta Adherens
  • The most common type
  • The placenta fails to contract away from the womb due to weak uterine contractions.
Trapped Placenta
  • The placenta detaches from the womb but gets stuck behind a partly closed cervix.
Placenta Accreta

Signs of a Retained Placenta

If the placenta does not come out within the expected time, you may notice:
  • Continuous heavy bleeding after childbirth
  • Severe abdominal cramps or pain
  • Foul-smelling vaginal discharge
  • A feeling of pressure or fullness in the womb
  • Signs of shock, like dizziness, sweating, or rapid heartbeat

Why a Retained Placenta is Risky

If not removed, a retained placenta can lead to complications:
  • Postpartum Haemorrhage (PPH): Severe blood loss that can be life-threatening if not treated quickly.
  • Infection: Retained tissue may lead to a uterine infection, causing fever, chills, and discomfort.
  • Scar Tissue Formation: In some cases, scar tissue can develop in the womb, affecting future fertility.
  • Shock: Rapid blood loss can lead to shock, necessitating urgent medical attention.

Causes of Retained Placenta

Several factors increase the risk:
  • Giving birth before 34 weeks (preterm delivery)
  • Prolonged labour or speedy labour
  • Previous history of retained placenta
  • Stillbirth
  • The placenta is attaching abnormally deeply into the wall of the womb.

How Retained Placenta is Diagnosed

Doctors or midwives carefully monitor the third stage of labour. They check:
  • How long does it take for the placenta to pass
  • Amount of blood loss
  • Whether the placenta appears complete once delivered
If the placenta has not been expelled within 30 minutes, medical intervention is usually considered.

Treatment Options

If the placenta does not come out naturally, different steps may be taken:
Manual Removal
  • A trained doctor gently removes the placenta by hand.
  • This is usually done under anaesthesia to ensure comfort.
Medications
  • Medicines may be given to help the womb contract and expel the placenta.
Surgical Options
  • In rare cases, surgery may be needed to remove placental tissue.
  • This is more common in cases of placenta accreta.

Preventive Care During Pregnancy

While not always preventable, you can take some steps to reduce risk:
  • Regular antenatal check-ups
  • Informing doctors about previous childbirth experiences
  • Early detection of placenta-related complications through ultrasound
  • Ensuring delivery in a hospital or centre with emergency facilities

What You Should Do

If you or someone close has recently delivered a baby, remember:
  • Do not ignore heavy bleeding or severe pain after delivery.
  • Always ensure the placenta is checked for completeness.
  • Seek immediate medical care if symptoms of retained placenta appear.

Recovery After Retained Placenta

With timely treatment, recovery is usually smooth. You may need:
  • Rest and proper hydration
  • Antibiotics are used if an infection is present
  • Iron-rich foods or supplements if blood loss was significant
  • Emotional support, as the experience can be stressful

Why Timely Care Matters in India

In India, postpartum haemorrhage remains a leading cause of maternal deaths. Retained placenta is a major reason. Quick hospital care, provided by skilled staff and backed by emergency support, saves lives.

Key Takeaways

  • The placenta must be expelled within 30 minutes of childbirth.
  • A retained placenta can lead to heavy bleeding, infection, or complications if ignored.
  • Immediate medical care, whether through medication, manual removal, or surgery, is necessary.
  • Recovery is possible with proper treatment and support.
Pregnancy and childbirth require care beyond delivering the baby. The placenta, often overlooked, remains important after birth. If not removed, risks may arise. With awareness and prompt medical support, a retained placenta can be managed safely. Stay informed, listen to your body, and seek timely care.

FAQs on Placenta Retention After Childbirth: Causes, Symptoms, and Treatment in Detail

  1. Can a retained placenta pass on its own after many hours?
    Sometimes, small fragments pass naturally, but waiting is not safe. If not expelled within 30 minutes, medical assistance is required.
  2. Does a retained placenta always require surgery?
    No, not always. Manual removal of medicines is usually effective. Surgery is required only in rare cases, especially when the placenta is abnormally attached.
  3. Can a retained placenta affect future pregnancies?
    If treated quickly, most people recover fully without complications. However, in cases of placenta accreta or scarring, future pregnancies may need closer monitoring.
  4. Is a retained placenta common in India?
    While not extremely common, a retained placenta is a known cause of postpartum haemorrhage in India. Awareness and access to timely care are crucial for preventing risks.
  5. How long does recovery take after treatment?
    Recovery typically takes a few weeks, although the duration varies. Rest, proper nutrition, and follow-up visits all play a crucial role in the healing process.
