How Common is Hemorrhaging After Birth? | Understanding Risks

Postpartum hemorrhaging, or excessive bleeding after birth, occurs in about 1 to 5% of deliveries and is a leading cause of maternal complications worldwide. It is defined as losing more than 500 ml of blood after vaginal delivery or 1,000 ml after a cesarean section.

How Common is Hemorrhaging After Birth? | What You Need to Know About Postpartum Bleeding

Postpartum hemorrhage (PPH) is one of the most serious complications that can occur after childbirth. I remember the worry I felt when I first learned about it during my pregnancy preparation classes. So, how common is hemorrhaging after birth? Approximately 1 to 5% of women experience postpartum hemorrhage, which makes it a relatively rare event, but one that can still have significant consequences if not properly managed. 

PPH is defined as losing more than 500 milliliters of blood after a vaginal delivery or more than 1,000 milliliters after a cesarean section. In this article, we’ll explore the causes, risk factors, symptoms, and treatments for postpartum hemorrhage, as well as ways to reduce the risk.

What is Postpartum Hemorrhage?

Postpartum hemorrhage refers to excessive bleeding following childbirth, which can be classified into two types: primary (or early) PPH and secondary (or late) PPH.

1. Primary Postpartum Hemorrhage

Primary PPH occurs within the first 24 hours after delivery and is the most common type. It usually results from issues such as uterine atony (failure of the uterus to contract), retained placenta, or trauma to the birth canal.

  • Tip: Most cases of primary PPH are detected and treated quickly in hospital settings, where healthcare providers can act promptly to stop the bleeding.

2. Secondary Postpartum Hemorrhage

Secondary PPH occurs more than 24 hours but within six weeks after delivery. It is less common and is often caused by retained placental tissue, infection, or problems with blood clotting.

  • Tip: If you experience heavy bleeding after being discharged from the hospital, it’s crucial to contact your healthcare provider immediately.

Causes of Postpartum Hemorrhage: Why Does It Happen?

PPH occurs when the body fails to stop the bleeding after the baby and placenta are delivered. There are several reasons this can happen, and understanding the causes can help you prepare and discuss your risks with your healthcare provider.

1. Uterine Atony

Uterine atony, or the failure of the uterus to contract after childbirth, is the most common cause of PPH. After delivery, the uterus should contract to compress the blood vessels where the placenta was attached. When the uterus doesn’t contract effectively, it can lead to heavy bleeding.

  • Tip: Doctors often use uterotonic medications (like oxytocin) to help stimulate uterine contractions immediately after birth, reducing the risk of uterine atony.

2. Retained Placental Tissue

Retained placenta occurs when all or part of the placenta remains attached to the uterine wall after delivery. This can prevent the uterus from contracting properly and lead to excessive bleeding.

  • Tip: Your healthcare provider will examine the placenta after delivery to ensure it has been fully expelled, but in some cases, retained tissue may be discovered later.

3. Trauma During Delivery

Vaginal or cervical tears, especially after a difficult or assisted delivery (e.g., forceps or vacuum extraction), can also cause hemorrhage. These tears may not close naturally and require stitches to stop the bleeding.

  • Tip: Careful monitoring during and after delivery can help identify any tears or injuries that could lead to excessive bleeding.

4. Coagulation Disorders

In rare cases, PPH is caused by a problem with the blood’s ability to clot. This can be due to pre-existing clotting disorders or conditions like disseminated intravascular coagulation (DIC), which can occur in response to pregnancy complications like preeclampsia or infection.

  • Tip: If you have a history of clotting disorders, make sure your healthcare provider is aware so they can monitor you closely during labor and delivery.

Retained PlacentaPlacenta or fragments remain in the uterusManual removal or surgery may be needed
Trauma During DeliveryTears or injuries to the vaginal or cervical areaStitches or repair needed to stop bleeding
Coagulation DisordersBlood clotting issues prevent proper clot formationBlood tests and clotting factor replacements

Risk Factors for Postpartum Hemorrhage

While PPH can occur in any delivery, certain factors can increase the risk. It’s important to be aware of these risks so you and your healthcare team can be prepared.

1. Prolonged Labor or Rapid Delivery

Both prolonged labor and very rapid delivery can increase the risk of PPH. In a prolonged labor, the uterus may become fatigued and less able to contract effectively, while a fast delivery may cause trauma to the birth canal.

  • Tip: If you’re experiencing either of these scenarios, your doctor may take extra precautions to prevent hemorrhaging by administering medications or closely monitoring your contractions.

2. Multiple Pregnancies

Carrying twins, triplets, or more can increase the risk of PPH because the uterus is stretched more than in a single pregnancy, making it harder for it to contract effectively after birth.

  • Tip: If you’re carrying multiples, discuss the potential risks of PPH with your healthcare provider to create a proactive birth plan.

3. High Blood Pressure or Preeclampsia

Conditions like preeclampsia, which causes high blood pressure during pregnancy, can lead to clotting issues that increase the risk of PPH. Women with preeclampsia are also at higher risk for requiring interventions like cesarean sections, which carry a greater risk of hemorrhage.

  • Tip: Managing blood pressure during pregnancy and being aware of the signs of preeclampsia can help reduce your overall risk of PPH.

4. History of PPH

Women who have experienced postpartum hemorrhage in previous deliveries are more likely to experience it again. If you have a history of PPH, it’s essential to inform your healthcare provider so they can take preventive measures.

  • Tip: Ensure that your healthcare team is fully informed about any previous PPH episodes so they can monitor you closely after delivery.

Signs and Symptoms of Postpartum Hemorrhage

Recognizing the signs of PPH is critical for timely intervention. Postpartum hemorrhage can escalate quickly, so it’s important for both healthcare providers and mothers to be aware of the symptoms.

1. Excessive Bleeding

The most obvious sign of PPH is excessive bleeding that doesn’t slow down after delivery. This bleeding may be vaginal or from the cesarean incision and is usually much heavier than normal postpartum bleeding (also called lochia).

  • Tip: If you’re soaking through more than one pad an hour or passing large clots, notify your healthcare provider immediately.

2. Drop in Blood Pressure

A sudden drop in blood pressure, which may cause dizziness, weakness, or fainting, is a sign that your body is losing a significant amount of blood. This can lead to shock if not treated promptly.

  • Tip: If you feel lightheaded, dizzy, or weak after delivery, alert your healthcare team right away.

3. Rapid Heart Rate

A rapid or racing heart rate is another sign that your body is trying to compensate for blood loss. This is often accompanied by feelings of panic or anxiety.

  • Tip: Don’t hesitate to mention any feelings of an irregular or fast heart rate to your doctor, as this could indicate PPH.

4. Swelling and Pain in the Lower Abdomen

If the uterus is not contracting properly, it can become enlarged and painful, causing noticeable swelling in the lower abdomen. This can also contribute to ongoing blood loss.

  • Tip: Ask your healthcare provider to check for signs of uterine atony if you feel persistent pain or swelling in your abdomen.

How Postpartum Hemorrhage is Treated

If postpartum hemorrhage is diagnosed, swift action is required to stop the bleeding and prevent complications. Treatment depends on the cause of the hemorrhage and may involve one or more of the following methods:

1. Uterine Massage

If uterine atony is the cause of PPH, healthcare providers may perform a uterine massage to encourage contractions and reduce bleeding. This is often one of the first steps in managing hemorrhage after delivery.

  • Tip: Uterine massage can be uncomfortable, but it is a quick and effective way to stimulate contractions and stop bleeding.

2. Medications

Medications such as oxytocin, misoprostol, or ergometrine are commonly used to stimulate uterine contractions and help control bleeding. These medications are often given immediately after birth to prevent or treat hemorrhage.

  • Tip: If you have a history of PPH, your healthcare provider may administer these medications preventively right after delivery.

3. Surgical Interventions

In severe cases, surgery may be required to stop the bleeding. This could include procedures like removing retained placental tissue or, in extreme cases, performing a hysterectomy (removal of the uterus) to save the mother’s life.

  • Tip: While surgical interventions are rare, it’s important to discuss the potential risks with your healthcare provider, especially if you have risk factors for PPH.
