The body's hemostasis system requires careful regulation in order to work properly. If the blood does not clot sufficiently, it may be due to bleeding disorders such as [[hemophilia]] or [[immune thrombocytopenia]]; this requires careful investigation. Over-active clotting can also cause problems; [[thrombosis]], where blood clots form abnormally, can potentially cause [[embolisms]], where blood clots break off and subsequently become lodged in a vein or artery.
