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.
Causes of Hemophilia a
- Inheritance. You can inherit it from your parents through genes.
- Mutation. It can also happen when a certain gene changes before you’re born.
- Acquired. It is a rare, dangerous form of hemophilia a. It results from neither inheritance nor mutation, but can be related to pregnancy, cancer, the use of certain medications, etc. And under this circumstance, no cause can be found in about half of cases.
