Inherited Blood-Clotting Problems - Topic Overview

Some people are born with an increased tendency to form blood clots. This makes them more likely to get blood clots in the legs (deep vein thrombosis) and in the lungs (pulmonary embolism). This tendency is due to inherited blood-clotting problems, which are often related to:

  • Mutated genes (such as factor V Leiden, factor II).
  • Decreased amounts of certain proteins. These may include protein C, protein S, and antithrombin III.
  • Increased levels of other substances. These may include antiphospholipid and lupus anticoagulant.

Many of these blood-clotting irregularities can be found with special tests. If your doctor suspects that you may have an inherited blood-clotting problem, discuss whether you need testing.

Blood Clots

Blood has a seemingly impossible job: It must flow continuously and smoothly throughout your body for an entire lifetime, but quickly shut off to prevent spills when you get a cut or injury. Blood clots are healthy and lifesaving when they stop bleeding. But they can also form when they aren't needed and cause a heart attack, stroke, or other serious medical problems.
