Some medical conditions can also make patients susceptible to bleeding. These are conditions that affect the normal hemostatic (bleeding-control) functions of the body. Such conditions either are, or cause, [[bleeding diathesis|bleeding diatheses]]. [[Hemostasis]] involves several components. The main components of the hemostatic system include [[platelets]] and the [[blood coagulation|coagulation]] system.

 

 

There are several named coagulation factors that interact in a complex way to form blood clots, as discussed in the article on [[coagulation]]. Deficiencies of coagulation factors are associated with clinical bleeding. For instance, deficiency of Factor VIII causes classic [[hemophilia A]] while deficiencies of Factor IX cause "Christmas disease"([[hemophilia B]]). Antibodies to Factor VIII can also inactivate the Factor VII and precipitate bleeding that is very difficult to control. This is a rare condition that is most likely to occur in older patients and in those with [[autoimmune]] diseases. Another common bleeding disorder is [[Von Willebrand disease]]. It is caused by a deficiency or abnormal function of the "Von Willebrand" factor, which is involved in platelet activation. Deficiencies in other factors, such as factor XIII or factor VII are occasionally seen, but may not be associated with severe bleeding and are not as commonly diagnosed.
