Coagulation (clotting).

Coagulation, or clotting, is the process by which the body slows and stops bleeding by turning part of the blood into a solid or semisolid substance. In most circumstances, the body starts this process automatically when there is an injury. However, in some instances, something interferes with the complex process. Interference can come from a pharmaceutical product, some foods, and certain health conditions. Coagulation issues can result from blood that clots too quickly, not quickly enough, or not at all. These clotting issues can be temporary or permanent and can cause other problems.
