Some Information About Hemophilia A

Definition of Hemophilia a

There are two types of hemophilia:

  • Hemophilia A(classic hemophilia) is most common. It occurs in about 80% of people with hemophilia.
  • Hemophilia B(Christmas disease) is less common. It occurs in about 20% of people with hemophilia.

With hemophilia a, your body doesn’t have enough of a protein called factor VIII. Without such protein, your body is unable to make clots and stop bleeding. Hemophilia a can be further separated into three types according to its factor VIII level:

  •  Mild hemophilia: 5% to 40% of the normal factor VIII level
  •  Moderate hemophilia: 1% to 5% of the normal factor VIII level
  • Severe hemophilia: Less than 1% of the normal factor VIII level

Most people who have hemophilia A have moderate or severe symptoms.
