Are hypercoagulable states dangerous?

Hypercoagulable states can be dangerous, especially when these conditions are not properly identified and treated. People with hypercoagulable states have an increased risk for blood clots developing in the arteries (blood vessels that carry blood away from the heart) and veins (blood vessels that carry blood to the heart). A clot inside a blood vessel is also called a thrombus or an embolus.

Blood clots in the veins or venous system can travel through the bloodstream and cause deep vein thrombosis (a blood clot in the veins of the pelvis, leg, arm, liver, intestines or kidneys) or a pulmonary embolus (blood clot in the lungs).

Blood clots in the arteries can increase the risk for stroke, heart attack, severe leg pain, difficulty walking, or even the loss of a limb.
