Women can and do have bleeding disorders. Despite long-standing misconceptions about bleeding disorders in women, women’s voices and experiences are now being taken more seriously.

Symptoms of bleeding disorders in women

You may have a bleeding disorder if you have one or more of the following symptoms:

  • Heavy menstrual periods
    • Bleeding for more than 7 days, from the time it began until it stopped
    • Flooding or gushing of blood, limiting daily activities such as work, exercise or social activities
    • Passing clots that are bigger than a quarter
    • Changing tampon and/or pad every 2 hours or less on heaviest day
  • Being told you are “low in iron” or have anemia
  • Having bleeding symptoms and someone in your family has a bleeding disorder, such as von Willebrand disease, or a clotting factor deficiency, such as hemophilia
  • Heavy bleeding from dental surgery, other surgery, or childbirth.
  • Frequent nose bleeds that last longer than 10 minutes
  • Bleeding from cuts lasting longer than 5 minutes
  • Easy bruising (weekly, raised and larger than a quarter)

If you have one or more of these symptoms, talk to your doctor or other healthcare professional.

The most common bleeding disorder in women and girls is von Willebrand disease (VWD). It affects up to 1% of the U.S. population.1 VWD is an inherited bleeding disorder. It is caused by a defect in or deficiency of von Willebrand factor, a protein the blood needs for clotting. VWD affects men and women equally, but women can have more symptoms due to heavy menstrual bleeding (periods.)

Women and girls can also have mild hemophilia. Women who carry the gene for hemophilia can have factor levels that are low, resulting in a diagnosis of mild hemophilia. Sometimes these women are referred to as “symptomatic carriers.” There are many rare factor disorders (link), including factor I, II, VI, VII, XI and XIII deficiency that affect men and women equally.

Although men and women with bleeding disorders have similar symptoms, such as bleeds into joints and tissues, women can experience added complications during menstruation, pregnancy, labor and delivery. Some doctors are not familiar with bleeding disorders in women, resulting in many of women going undiagnosed or misdiagnosed. Women with undiagnosed and untreated bleeding disorders risk serious complications.

If you have symptoms of a bleeding disorder, it is important to get a proper diagnosis and treatment from a specialist, called a hematologist. In the U.S., there is a network of hemophilia treatment centers (HTCs) that provide comprehensive care to patients with hemophilia and other bleeding disorders, and even some that have specialty services for women and girls. HANDI, our information resource center, can provide information on bleeding disorders and the nearest HTC.
