Women and Bleeding Disorders



While many people think of bleeding disorders as primarily affecting males (as in the case with hemophilia), women can have bleeding disorders too. Certain bleeding disorders, like von Willebrand’s disease (vWD) for instance, occur with equal frequency in both males and females.

Von Willebrand’s disease, is caused by a deficiency or defect in von Willebrand factor (VWF), a vital blood protein critical for normal blood clotting.

Coagulation (Clotting) Disorders
Bleeding disorders are really coagulation disorders. People with bleeding disorders do not bleed faster, they simply do not stop bleeding the way they should.

Clotting is the Body’s Way of Preventing Blood Loss
Normally, when a blood vessel is injured, the body takes immediate action to prevent excessive blood loss. Blood, which is usually in a liquid state, goes through a complex, interconnected process in order to form a solid clot.

This process, called a clotting cascade, requires multiple steps, 13 different blood protein factors , as well as other enzymes to complete.

If a given factor is missing or defective, a clot cannot form properly. Even if it does form, it will be too weak to stop the bleeding or prevent bleeding from recurring.

Heavy Periods and Bleeding Disorders in Women
The most common symptom women with bleeding disorders experience is menorrhagia, or heavy menstrual bleeding. Because the severity of symptoms can vary, and many women don’t know that prolonged or heavy bleeding during menstruation (periods) can be a sign of a bleeding disorder.

1% of All Women in the United States Have a Bleeding Disorder

This means that many women with a bleeding disorder might not be aware of it. The Center for Disease Control (CDC) estimates that as many as 1% of all women in the U.S. may have a bleeding disorder. While excessive menstrual bleeding is the most common symptom of a bleeding disorder in women, it is not the only one. Symptoms of a bleeding disorder in a females can include:
• Anemia (or being told you have “low iron”)
• Heavy or prolonged periods (lasting more than 7 days), passing clots larger than a quarter, having to change your pad every two hours or less on heavy flow days, or having gushing/flooding blood that seeps through pads or clothing
• Excessive bruising (bruises that are larger in size or swell) and or easy bruising that may occur frequently (weekly)
• Exaggerated bleeding after minor cuts (lasting longer than five minutes)
• Excessive or prolonged bleeding after dental work, surgery or childbirth
• Frequent nosebleeds, or nosebleeds that last longer than ten minutes
• Having a blood relative that has a bleeding disorder such as hemophilia or von Willebrand’s disease

Hemophilia and Women
While it is true that women are hemophilia carriers (meaning that they carry and can pass down the specific gene mutation which causes hemophilia), they can also experience symptoms as well.

Known as symptomatic carriers, women who carry the gene responsible for hemophilia, may experience symptoms similar to those in males with mild hemophilia. If they undergo surgery, go through childbirth, or are involved in an accident, they can bleed excessively and require medical intervention.

Asymptomatic Female Carriers of Hemophilia
Many carriers are asymptomatic, meaning they do not show symptoms in their day to day lives. If, however, they have an injury or go through childbirth, they may experience prolonged bleeding which can be life-threating.

More About Hemophilia
Hemophilia is a rare genetic disorder caused by either not having enough of factor VIII (hemophilia A) or factor IX (hemophilia B). Factors can also be at normal levels, yet defective in some way.

Hemophilia is caused by a gene mutation carried on the X chromosome (one of the chromosomes responsible for gender). The X chromosome also contains the gene with instructions for factor VIII (8)

Females typically have two X chromosomes (XX), while a male usually has an X and a Y chromosome combination (XY). Males inherit one X chromosome from their mother, which gives them a 50% chance of passing being born with hemophilia, and a Y chromosome from their father.

Girls Inherit an X from Dad, and an X from Mom
Females inherit an X chromosome from their mother and a X chromosome from their father. If a woman is a carrier, any daughters she may have also has a 50-50 chance of being a carrier. It should be noted that if a male with hemophilia has a daughter, she will inherit his affected X chromosome and the daughter will have a 100% chance of being a carrier.

Females Can be Born with Hemophilia
In rare cases where a female is born with hemophilia (rather than just being a carrier), both her X chromosomes must carry the defect (her father had hemophilia and her mother was also a carrier), or one has the gene mutation and the other is either inactive or missing. This situation is very uncommon.

Von Willebrand’s Disease

By far, the most common bleeding disorder in women is von Willebrand’s disease (vWD). An estimated 3.2 million people in America have von Willebrand’s disease. It occurs when a certain blood protein known as von Willebrand’s factor (I VWF) is either deficient or defective.

Named after the physician who discovered it, von Willebrand’s disease has three main types and several subtypes. For more information about types and subtypes of von Willebrand’s disease, please click here.

Females with bleeding disorders may experience anemia (lower than normal levels of red blood cells in the blood), leading to feelings of being overly tired and or weak. They may also have other symptoms such as those listed in the previous section.
