Types of Hemophilia
Your blood needs to clot in order to fend off further bleeding or infection. The blood clotting process involves specific clotting factors. A shortage of one of these clotting factors results in hemophilia.
The three main hemophilia types are:
||Also called “classical” or low clotting factor VIII (8). This is the most common type of hemophilia.
||Also called “Christmas disease” or low clotting factor IX (9). This is the second most common type of hemophilia.
||Is very rare, and is caused by a low clotting factor XI (11). Sometimes it’s called Rosenthal syndrome.
Not everyone with hemophilia bleeds the same. Hemophilia is classified as mild, moderate, or severe, depending on how much of the clotting factor is missing. Normal levels of the factor VIII (8) or IX (9) protein are above 50 percent.
- Severe hemophilia. You are missing clotting factor VIII (8) or IX (9). You may have excessive bleeding after injury, dental work, or surgery, and you may bleed for no clear reason.
- Moderate hemophilia. You have between 1 and 5 percent of the clotting factor in your blood. Some people with moderate hemophilia will have spontaneous bleeding episodes; however, others only bleed with trauma, surgery, or dental work.
- Mild hemophilia. You have over 5 percent of the affected factor in your blood. You may bleed with injury, dental work, or surgery. Bleeding without a clear cause is rare.
