Overview
PPH stands for postpartum hemorrhage, which is a serious complication involving excessive bleeding after childbirth. It is one of the leading causes of maternal illness and death worldwide, but with prompt recognition and treatment, most people recover well.
What Is PPH?
Definition
- Postpartum hemorrhage (PPH) is defined as blood loss greater than 500 milliliters (mL) after a vaginal birth or more than 1,000 mL after a cesarean birth. However, the diagnosis can also be based on symptoms of blood loss, such as low blood pressure, rapid heartbeat, or signs of shock, since blood loss can sometimes be underestimated or hidden by normal pregnancy changes.Introduction - Management of Postpartum Hemorrhage - NCBI BookshelfPostpartum hemorrhage (PPH) is commonly defined as blood loss exceeding 500 milliliters (mL) following vaginal birth and 1000 mL following cesarean.1 Definitions vary, however, and diagnosis of PPH is subjective and often based on inaccurate estimates of blood loss.1-4 Moreover, average blood ...Read full articleSource: ncbi.nlm.nih.govPostpartum Hemorrhage: Overview, Etiology, DiagnosisAcquired coagulopathies during ... fluid embolism, or sepsis. ...

Causes and Risk Factors
Main Causes (The "Four T's")
- Tone: Uterine atony (the uterus does not contract well), which is the most common cause.
- Trauma: Injury to the birth canal, such as tears or lacerations.
- Tissue: Retained placenta or blood clots.

Risk Factors
- Some people have identifiable risk factors, such as:
- Multiple pregnancy (twins, triplets, etc.)
- Prolonged or rapid labor
- Large baby (macrosomia)
- Placenta previa or abruption (placenta issues)
- Previous history of PPH
- High blood pressure or preeclampsia
- Use of certain medications or assisted reproductive technologies
- Cesarean or operative vaginal delivery (forceps/vacuum)

Summary
PPH is excessive bleeding after childbirth and is a major cause of maternal health complications. It can happen to anyone after delivery, even without risk factors. The most common cause is the uterus not contracting well after birth, but other causes include trauma, retained tissue, and clotting problems. Prompt medical attention and treatment are critical for a good outcome.
