What is excessive uterine bleeding?
Some bleeding after you deliver a baby is normal. More than 4 cups (more than 1000 mL) of blood loss after vaginal delivery is excessive uterine bleeding.
The most common reason for too much bleeding is your uterus stays stretched out and isn't contracting (squeezing) like it's supposed to
Doctors treat too much bleeding by massaging your belly and giving you medicines to help your uterus contract
Doctors may give you a blood transfusion
Rarely, you'll need surgery
What causes too much bleeding during delivery?
Most often, you have too much bleeding because:
Your uterus doesn't contract after delivery like it's supposed to
Other reasons for too much bleeding include:
Your vagina or cervix (the lower part of your uterus) was torn during delivery
A bleeding disorder that stops your blood from clotting
Part of your placenta (the afterbirth) stayed inside your uterus after delivery
You have a higher risk for bleeding if you:
Have had a lot of babies
Were in labor for a long time
Deliver more than one baby (such as twins or triplets)
Deliver a very large baby
What can doctors do to stop me from bleeding too much?
Before you go into labor, doctors take steps to prevent or to prepare for bleeding after delivery.
They check you for risks of bleeding, such as having too much amniotic fluid or a bleeding disorder
If you have an unusual blood type, doctors make sure that your blood type is available
They try to deliver your baby as slowly and gently as possible
After delivery, doctors watch you for at least 1 hour—they make sure your uterus has contracted and check for bleeding
How will doctors know if I am bleeding too much?
Watch for too much blood loss
Press on your belly area to see if your uterus is firm like it should be
Watch your blood pressure and how fast your heart beats—a drop in blood pressure or a rapid heart rate may mean you're losing too much blood
What happens if I start bleeding too much?
Firmly press on and massage your belly to help your uterus contract
Check for tears in your vagina and cervix
Give you medicines to make your uterus contract
Give you fluids or blood through your vein to replace lost blood
Pressing on your belly helps the uterus contract and shut off bleeding. There are several different medicines doctors may give in your IV or as a shot in your arm.
If bleeding continues, doctors may do surgery including:
Scraping the inside of your uterus to remove any leftover pieces of the placenta (afterbirth)
Putting a balloon inside your uterus to cut off blood flow
Packing the inside of your uterus with gauze
Putting in stitches around the bottom of your uterus
Blocking major veins that bring blood to your uterus
As a last resort, a hysterectomy (removing your uterus)
