Postpartum hemorrhage is excessive blood loss in a woman after childbirth. It is called primary when it is within the first 24 hours after childbirth. Secondary (or delayed) postpartum hemorrhage occurs between 24 hours-6 weeks after childbirth.
Some blood loss is normal. However, postpartum hemorrhage is a potentially serious condition that often goes unrecognized. Any excessive blood loss can put a woman at considerable risk. Talk with your doctor if you have any concerns about blood loss after giving birth.

Postpartum hemorrhage can be caused by: A loss of muscle tone in the uterus after birthWounds in the birth canalFailure to deliver the placentaMaternal bleeding disorders that prevent blood clotting (rare)
In rare cases, uterine inversion or
may also cause postpartum hemorrhage.
Postpartum hemorrhage may be more common in
Asian and Hispanic women.
Factors leading up to labor that may increase your chance of postpartum hemorrhage include: History of previous postpartum hemorrhagePre-eclampsiaProblems with the placentaObesityFirst pregnancyMultiple pregnancy, which may create high amniotic fluid levels
Complications of labor and delivery that may increase your chance of postpartum hemorrhage include:
Interventions, such as:
Augmented labor—methods that stimulate or speed the progression of labor when it is delayed or stoppedForceps or vacuum deliveryEpisiotomyCesarean sectionProlonged laborLarge fetusBacteria infection of the membranes and fluid surrounding the fetus—chorioamnionitisStillbirth
Forceps and Vacuum Delivery

The most obvious sign of postpartum hemorrhage is heavy vaginal bleeding. If the bleeding is not obvious, other signs may include: Lightheadedness and faintingIncreased heart rateDecreased blood pressureSwelling and pain in the vaginal and perineal area
Your doctor will ask about your symptoms. A physical exam will be done. The doctor will check your perineum, vagina, cervix, and uterus for bleeding. Other tests may include: Blood testsBlood clotting testsClot observation testsMonitoring the number of saturated pads or sponges that absorb bloodMonitoring blood pressure and pulse
Imaging tests evaluate internal body structures. These may include: UltrasoundAngiography
Treatment is based on the severity of bleeding. Treatment options include:
You may need IV fluids or an oxygen mask. In severe cases, resuscitation or a
may be necessary.
A massage technique called bimanual uterine massage can control bleeding. A doctor or nurse will place one hand in your vagina to push on your uterus, while the other hand pushes down on your abdomen. This action will cause a relaxed uterus to contract, thus slowing bleeding.
Bleeding can be caused by a tear in your genital tract or other trauma. The tear will be stitched. In addition, tissue from a retained placenta may need to be removed.
Your doctor may prescribe uterotonics or prostaglandins to stimulate contraction of the uterus.
In some cases, surgery may be needed to stop bleeding. Procedures include: Uterine packing—sterile materials or a special tamponade device is placed inside the uterine cavity to compress the bleeding areaRepair of arteriesUterine curettage—scraping the lining of the uterusRepair of hematomaRemoval of retained placentaUterine artery embolization—non-invasive procedure to block the uterine arteryRemoval of the uterus—hysterectomy
To help reduce your chance of postpartum hemorrhage: Receiving continuous nursing care during laborMake sure you are closely monitored during the third stage of labor, when the placenta is delivered
