Postpartum Hemorrhage (PPH): Causes, Warning Signs, Prevention, and Treatment

 

Childbirth is one of the most beautiful and life-changing experiences in a woman's life. While most mothers recover safely after giving birth, some may experience serious complications that require immediate medical attention. One of the most dangerous of these complications is Postpartum Hemorrhage (PPH).

Postpartum hemorrhage is one of the leading causes of maternal deaths worldwide, particularly in developing countries. However, with early recognition, skilled healthcare, and prompt treatment, most women recover completely.

Every expectant mother, family member, and caregiver should understand what postpartum hemorrhage is, why it happens, its warning signs, and how it can be prevented. Knowing the danger signs can save a mother's life.

What Is Postpartum Hemorrhage (PPH)?

Postpartum Hemorrhage (PPH) is excessive bleeding that occurs after the birth of a baby.

It is defined as:

• Blood loss of 500 mL or more after a vaginal delivery.
• Blood loss of 1,000 mL or more after a Caesarean section.

However, healthcare providers also assess the mother's overall condition because even smaller amounts of blood loss can be dangerous in some women, especially those with anemia.

PPH is considered an obstetric emergency and requires immediate treatment.

Types of Postpartum Hemorrhage

1. Primary (Early) Postpartum Hemorrhage

This occurs:

• Within the first 24 hours after childbirth.

It is the most common type.

2. Secondary (Late) Postpartum Hemorrhage

This occurs:

• From 24 hours up to 6 weeks after delivery.

It is usually caused by retained placental tissue or infection.

Why Is Postpartum Hemorrhage Dangerous?

During pregnancy, the mother's body prepares for blood loss during delivery. However, when bleeding becomes excessive, it can quickly lead to:

• Severe anemia.
• Low blood pressure.
• Shock.
• Organ failure.
• Loss of consciousness.
• Maternal death.

Prompt treatment can prevent these complications.

Causes of Postpartum Hemorrhage

Healthcare providers commonly remember the causes using the "Four Ts."

1. Tone (Uterine Atony)

This is the most common cause of postpartum hemorrhage.

After delivery, the uterus should contract firmly to close the blood vessels where the placenta was attached.

If the uterus remains soft and relaxed (uterine atony), heavy bleeding occurs.

Risk factors include:

• Prolonged labor.
• Rapid labor.
• Overstretched uterus.
• Twin or multiple pregnancy.
• Large baby (macrosomia).
• Polyhydramnios (too much amniotic fluid).
• High parity (many previous births).

2. Tissue (Retained Placenta)

If parts of the placenta or membranes remain inside the uterus after delivery, the uterus cannot contract properly, resulting in continued bleeding.

3. Trauma

Injuries during childbirth may cause heavy bleeding.

Examples include:

• Cervical tears.
• Vaginal tears.
• Perineal tears.
• Episiotomy extension.
• Uterine rupture (rare).
• Uterine inversion.

4. Thrombin (Blood Clotting Disorders)

Some women have problems with blood clotting, making it difficult for bleeding to stop.

Examples include:

• Disseminated Intravascular Coagulation (DIC).
• Severe preeclampsia.
• HELLP syndrome.
• Certain inherited bleeding disorders.

Risk Factors for Postpartum Hemorrhage

A woman has a higher risk if she has:

• Previous postpartum hemorrhage.
• Multiple pregnancy.
• Placenta previa.
• Placental abruption.
• Prolonged labor.
• Induced labor.
• Instrumental delivery.
• Caesarean section.
• Large baby.
• Severe anemia.
• High blood pressure.
• Blood clotting disorders.

Although these factors increase risk, postpartum hemorrhage can also occur unexpectedly in women without any known risk factors.

Signs and Symptoms of Postpartum Hemorrhage

The warning signs include:

• Heavy vaginal bleeding.
• Passing large blood clots.
• Soaking one sanitary pad within an hour.
• Dizziness.
• Fainting.
• Pale skin.
• Cold, clammy skin.
• Rapid heartbeat.
• Low blood pressure.
• Extreme weakness.
• Difficulty breathing.
• Confusion or loss of consciousness.

These symptoms require immediate emergency care.

How Is Postpartum Hemorrhage Diagnosed?

Healthcare providers diagnose PPH through:

Physical Examination

Assessing the amount of blood loss and checking the uterus.

Vital Signs

Monitoring:

• Blood pressure.
• Pulse.
• Respiratory rate.
• Oxygen level.

Blood Tests

These include:

• Full blood count (FBC).
• Blood grouping and cross-matching.
• Clotting profile.

Examination of the Birth Canal

To identify any tears or retained placental tissue.

Treatment of Postpartum Hemorrhage

Treatment begins immediately.

Step 1: Call for Help

A team of healthcare professionals is mobilized.

Step 2: Massage the Uterus

Gentle uterine massage stimulates contraction and helps reduce bleeding.

Step 3: Administer Uterotonic Drugs

Medicines that help the uterus contract include:

• Oxytocin.
• Misoprostol.
• Ergometrine (where appropriate).
• Carboprost (in selected cases).

Step 4: Intravenous Fluids

Large amounts of IV fluids are given to replace lost blood volume.

Step 5: Blood Transfusion

If blood loss is severe, blood or blood products may be transfused.

Step 6: Remove Retained Placental Tissue

If pieces of the placenta remain inside the uterus, they are carefully removed.

Step 7: Repair Tears

Any tears in the cervix, vagina, or perineum are repaired.

Step 8: Surgery

If bleeding cannot be controlled, surgery may be necessary.

Procedures may include:

• Uterine compression sutures.
• Balloon tamponade.
• Uterine artery ligation.
• Hysterectomy (removal of the uterus) as a life-saving last resort.

Prevention of Postpartum Hemorrhage

Many cases can be prevented through good maternity care.

Prevention includes:

• Regular antenatal care.
• Early detection and treatment of anemia.
• Delivery in a healthcare facility.
• Skilled birth attendance.
• Active management of the third stage of labor (AMTSL).
• Routine administration of oxytocin after delivery.
• Careful monitoring after childbirth.

Active Management of the Third Stage of Labor (AMTSL)

AMTSL is one of the most effective ways to prevent PPH.

It involves:

• Giving oxytocin immediately after birth.
• Controlled cord traction (when appropriate).
• Uterine massage after delivery of the placenta.

These measures help the uterus contract effectively and reduce blood loss.

Recovery After Postpartum Hemorrhage

Recovery depends on how much blood was lost and how quickly treatment was started.

Mothers are encouraged to:

• Rest adequately.
• Eat iron-rich foods.
• Take prescribed iron supplements.
• Drink enough fluids.
• Attend follow-up appointments.
• Seek medical care if bleeding increases again.

Most women recover fully with appropriate treatment.

Possible Complications

If not treated promptly, PPH may lead to:

• Severe anemia.
• Hypovolemic shock.
• Kidney failure.
• Blood clotting disorders.
• Organ damage.
• Maternal death.

Early intervention greatly reduces these risks.

Common Myths About Postpartum Hemorrhage

Myth 1: Heavy Bleeding After Childbirth Is Always Normal

False.

While some bleeding is expected, excessive bleeding is a medical emergency.

Myth 2: Postpartum Hemorrhage Only Happens After Vaginal Delivery

False.

It can occur after both vaginal births and Caesarean sections.

Myth 3: If You Had No Problems During Pregnancy, You Cannot Develop PPH

False.

PPH can occur even in women with healthy pregnancies.

Myth 4: Home Remedies Can Stop Severe Bleeding

False.

Postpartum hemorrhage requires urgent hospital treatment.

When Should You Seek Immediate Medical Help?

Go to the nearest hospital immediately if you experience:

• Heavy vaginal bleeding.
• Large blood clots.
• Fainting.
• Severe dizziness.
• Rapid heartbeat.
• Difficulty breathing.
• Fever after childbirth.
• Foul-smelling vaginal discharge.
• Severe abdominal pain.

Do not delay seeking medical care.

Conclusion

Postpartum hemorrhage is a life-threatening emergency that requires immediate recognition and treatment. Although it is one of the leading causes of maternal deaths, it is also one of the most preventable when women receive quality antenatal care, skilled birth attendance, and prompt medical intervention.

Every mother should understand the warning signs of excessive bleeding and never ignore symptoms such as soaking pads rapidly, passing large blood clots, dizziness, or fainting after childbirth. Delivering in a well-equipped healthcare facility and attending regular postnatal check-ups greatly reduce the risk of complications.

Remember, every minute counts in postpartum hemorrhage. Early treatment saves lives, protects mothers, and ensures they can enjoy the precious moments of welcoming their new baby.
