Hemophilia is a bleeding problem. People with hemophilia do not bleed any faster than normal, but they can bleed for a longer time. Their blood does not have enough clotting factor, a protein that controls bleeding.
Platelets are small cells that circulate in the blood. They are involved in the formation of blood clots and the repair of damaged blood vessels. Platelet function disorders are conditions in which platelets don’t work the way they should, resulting in a tendency to bleed or bruise.
For many years, people believed that only men could have symptoms of hemophilia and that women who “carry” the hemophilia gene do not experience symptoms themselves. We now know that many carriers do experience symptoms of hemophilia.
