Information for Patients


Blood Clots

Also called: Hypercoagulability

Normally, if you get hurt, your body forms a blood clot to stop the bleeding. After the bleeding stops and healing takes place, your body usually breaks down and removes the clot. But some people get too many clots or their blood clots abnormally. Many conditions can cause the blood to clot too much or prevent blood clots from dissolving properly.

Risk factors for excessive blood clotting include

Blood clots can form in, or travel to, the blood vessels in the brain, heart, kidneys, lungs, and limbs. A clot in the veins deep in the limbs is called deep vein thrombosis (DVT). DVT usually affects the deep veins of the legs. If a blood clot in a deep vein breaks off and travels through the bloodstream to the lungs and blocks blood flow, it is called a pulmonary embolism. Other complications of blood clots include stroke, heart attack, kidney problems, kidney failure, and pregnancy-related problems.Treatments for blood clots include blood thinners and other medicines.
