Postpartum hemorrhage
Postpartum hemorrhage (PPH) is excessive bleeding after childbirth and can become life-threatening within minutes. Rapid recognition, quantified blood loss and immediate coordinated treatment are central to preventing shock, organ injury and death.

Structured entity profile
Clinical profile
Overview
Postpartum hemorrhage is excessive bleeding after childbirth. WHO, FIGO and ICM issued consolidated guidance in 2025 emphasizing earlier objective detection and rapid treatment because many severe cases occur without obvious risk factors. [1] [2]
PPH affects millions of women each year and causes nearly 45,000 deaths globally according to WHO’s 2025 guideline launch materials. [2]
Symptoms and warning signs
Heavy or rapidly increasing vaginal bleeding is the obvious sign, but clinical deterioration can also appear as fast heart rate, falling blood pressure, dizziness, weakness, pallor, confusion or collapse. Internal or concealed bleeding can make visual blood loss underestimate severity. [1] [2]
SYMPTOM MATRIX
Postpartum hemorrhage is recognized by bleeding plus maternal condition
Do not wait for collapse: blood loss and abnormal vital signs should trigger an immediate response.
- Heavy or ongoing postpartum bleeding
- Blood pooling or rapidly soaking pads/drapes
- Fast heart rate
- Dizziness or marked weakness
- Pallor
- Boggy poorly contracted uterus
- Retained placental tissue
- Genital-tract laceration
- Bleeding despite a firm uterus
- Coagulation abnormality
- Low blood pressure
- Confusion or reduced consciousness
- Collapse
- Cold clammy skin
- Very low urine output
Postpartum hemorrhage is an emergency. Immediate obstetric resuscitation and source control are required.
Diagnosis
WHO 2025 recommends objective blood-loss measurement after birth and close monitoring of maternal vital signs. The new guidance supports acting at 300 mL of blood loss when abnormal vital signs are also present, rather than relying only on the traditional 500 mL threshold. [2]
At the same time, clinicians identify the cause by checking uterine tone, placental completeness, the genital tract and coagulation status. Laboratory tests support resuscitation but should not delay treatment. [1] [2]
Diagnostic pathway
Recognize bleeding early and search for the source while treating
Diagnosis and treatment occur in parallel because delay increases the risk of shock.
Postpartum hemorrhage is a clinical emergency; treatment should begin from the clinical picture and measured blood loss rather than wait for complete laboratory confirmation. Source [1]
The main causes of postpartum hemorrhage
A common framework is the “4 Ts”: tone (uterine atony), trauma (lacerations or uterine injury), tissue (retained placenta) and thrombin (coagulation problems). More than one cause can be present at the same time. [1]
Treatment and management
WHO’s 2025 guidance recommends immediate coordinated treatment after PPH is diagnosed. The MOTIVE bundle includes uterine massage, oxytocic medicines, tranexamic acid, intravenous fluids, vaginal/genital-tract examination and escalation if bleeding continues. [2]
Persistent or severe bleeding may require additional uterotonics, blood products, balloon tamponade, uterine artery procedures or surgery, including hysterectomy in life-threatening cases. Resuscitation and source control proceed together. [1] [2]
Treatment & care hub
Minutes matter: resuscitate and control the bleeding source together
PPH care is a coordinated emergency pathway rather than a single medication.
Massage + uterotonics
Support uterine contraction rapidly when atony is present or suspected.
Reduce ongoing bleeding
TXA is part of the recommended rapid treatment bundle when PPH is diagnosed.
Restore circulating volume
IV fluids and blood products are escalated according to blood loss, shock and laboratory findings.
Control the source
Tamponade, interventional procedures or surgery may be required when first-line treatment fails.
After a major postpartum hemorrhage
Follow-up may include treatment of anemia, monitoring for organ injury, discussion of what happened, and psychological support. Severe PPH can be traumatic and may affect future pregnancy planning. [1] [2]
New or increasing heavy bleeding after discharge warrants urgent medical assessment; patients should know this warning sign before leaving the birth facility.
Global burden
Postpartum hemorrhage causes nearly 45,000 maternal deaths each year
WHO identifies PPH as one of the leading childbirth complications worldwide.
Common questions
Frequently asked questions
It is excessive bleeding after childbirth that requires rapid clinical recognition and treatment because it can progress to shock.
Uterine atony—when the uterus does not contract effectively after birth—is a common cause.
Treatment is immediate and coordinated, commonly including uterine massage, uterotonics, tranexamic acid, IV fluids, examination for the bleeding source and rapid escalation if bleeding continues.
Yes. Many cases occur without an obvious pre-existing risk factor, which is why routine monitoring after birth is important.
Yes. Severe hemorrhage can cause anemia, organ injury, psychological trauma and can influence counseling for future pregnancies.

Estimating blood loss is imprecise, so I do not rely on the volume estimate alone. Vital signs and the woman’s overall clinical condition are essential, and hypotension can be a late sign of major blood loss.
