What is Hemophilia? Blood clotting, or coagulation, is the process that controls bleeding. It changes blood from a liquid to a solid. It's a complex process involving as many as 20 different plasma proteins, or blood clotting factors. Normally, a complex chemical process occurs using these clotting factors to form a substance called fibrin that stops bleeding. When certain coagulation factors are deficient or missing, the process doesn't occur normally.

In people with bleeding disorders, clotting factors are missing or don't work as they should. This causes them to bleed for a longer time, bruise easier and have greater joint pain than those whose blood factor levels are normal.
