Hemophilia

[hee-muh-fil-ee-uh]

World Hemophilia Day

Hemophilia is an inherited bleeding disorder, which means it can run in families. Blood does not clot properly in people with hemophilia. Blood contains proteins called clotting factors that are needed to stop bleeding. People with hemophilia have low amounts of either factor VIII (factor 8) or factor IX (factor 9) in their blood. A lower amount of factor in the blood typically leads to more severe hemophilia. The lower the amount of the factor, the more likely it is that bleeding will occur. Hemophilia occurs in about 1 of every 5,000 male births from all racial and ethnic groups. Females can also have hemophilia, but this is much more rare.

Prevention Tips

  • Hemophilia is a hereditary (inherited) disorder, which means it can be passed down in families. Any family history of bleeding, such as following surgery or injury, or unexplained deaths, should be discussed with a doctor.

  • Good quality medical care from doctors and nurses who are knowledgeable about hemophilia can help prevent some serious problems. Often the best choice is a hemophilia treatment center, which provides care for all issues related to the disorder.

  • About 1 in 5 people with hemophilia develop an inhibitor. Inhibitors make it less likely that clotting factor treatment will stop bleeding. It’s important for people with hemophilia to get tested yearly for inhibitors in order to detect them early.

  • Everyone should exercise regularly to stay healthy. People with hemophilia should avoid high-impact sports. For more information about sports and exercise, people with hemophilia should talk with a doctor or visit a hemophilia treatment center.
