What is hemophilia?

Clotting problem: Hemophilia is a hereditary blood disorder in which the person is deficient in one of the body's clotting factors (factor viii for hemophilia a and factor ix for hemophilia b). Therefore the blood does not clot correctly after an injury. Depending on severity, patients with hemophilia bleed and bruise easily and for a longer time. Some may even bleed into their joints, muscles, or brain.

Clotting disease: Hemophilia is a hereditary genetic disorder that impairs the body's ability to clot or stop bleeding. There are many factors involved in clotting and therefore, an abnormality in a few of these factors can cause a bleeding disorder or a hemophilia.
