It is not typical to screen for bleeding disorders, unless you are having certain types of major surgery or have known risk factors. Your doctor may do a blood test. If you are diagnosed with a bleeding disorder, your doctor may discuss your risk of passing your condition on to a future child.

You may have an increased risk for bleeding disorders because of your age, family history and genetics, other medical conditions and medicines, and your sex.

Your genes, or other causes such as medical conditions or medicines, can cause bleeding disorders. Sometimes a cause may not be known. Any problem that affects the function or number of clotting factors or platelets can lead to a bleeding disorder.

Bleeding disorders can be inherited, or they can be acquired, meaning you develop them during your lifetime. Acquired bleeding disorders are more common than inherited bleeding disorders.
