An Introduction to Bleeding Disorders

Hemophilia

Hemophilia is primarily an inherited disorder that does not allow blood to clot properly. There is a deficiency in the body of the necessary proteins, also called clotting factors, needed to stop bleeding. Hemophilia A is the deficiency of clotting factor VIII and according to the US Centers for Disease Control and Prevention (CDC), hemophilia occurs in approximately 1 in 5,617 male births.

Hemophilia B is the deficiency of clotting factor IX and affects about 1 in 25,000 males.

Von Willebrands

VWD is the most common bleeding disorder, found in up to 1% of the U.S. population. This means that 3.2 million (or about 1 in every 100) people in the United States have the disease. Although VWD occurs among men and women equally, women are more likely to notice the symptoms because of heavy or abnormal bleeding during their menstrual periods and after childbirth. There are 3 major types of VWD: Type 1, Type 2, and Type 3.
