Haemophilia is the name of several hereditary genetic illnesses. Hemophilia (heem-a-FILL-ee-ah) is a rare inherited bleeding disorder in which the blood does not clot normally. Bleeding may occur spontaneously or following injury.Hemophilia occurs in 2 forms, hemophilia A and B. Hemophilia A , also known as factor VIII deficiency, is the cause of about 80% of cases. Hemophilia B , which makes up the majority of the remaining 20% of cases, is a deficiency of factor IX.
Patients are classified as mild, moderate, or severe, based on the amount of factor present in the blood. In both forms, a gene is defective. The defective gene interferes with the ability of the body to produce the clotting factors that allow for normal clotting. The result is a tendency for abnormal, excessive bleeding. Persons with hemophilia may bleed for a longer time than others after an injury or accident. They also may bleed internally, especially in the joints (knees, ankles, and elbows).
The most common type of bleeding in hemophilia involves muscles and joints. Clotting is a injury to a blood vessel causes a complex chain of events that results in a blood clot. Clotting factors are proteins in the blood that work with platelets—a type of small blood cell—to help the blood to clot. Because it is missing or has low levels of one of these clotting factors.
Sometimes people with hemophilia need infusions of a clotting factor or factors to stop bleeding. Clotting is your body's reaction to bleeding and keeps you from losing too much blood. Losing too much blood can be life threatening and can damage your internal organs. This clotting process is also called blood coagulation. When blood vessels are damaged, clotting factors help the platelets stick together to plug cuts and breaks at the site of the injury. In people with hemophilia, blood does not clot as it should.
