Bleeding Disorders - Types - Types

You may develop a bleeding disorder if something in your body, such as a disease or a medicine, causes your body to stop making blood clotting factors or causes the blood clotting factors to stop working correctly. In addition, problems with your blood vessels can lead to bleeding.

Acquired bleeding disorders include:

• Disseminated intravascular coagulation (DIC)
• Liver disease-associated bleeding
• Vitamin K deficiency bleeding
• Von Willebrand disease and hemophilia, two conditions that are most often inherited, may also develop as a result of a medical condition.
• Other, rarer types of acquired bleeding disorders include deficiencies of certain factors, such as factor I, II, and V, that are named for the clotting factor causing the problem.
• Rarely, tangles of blood vessels, called arteriovenous malformations, can form in the brain or elsewhere in the body and lead to bleeding. These tangles may form before birth or later in life.

Inherited bleeding disorders include the following:

• Combined deficiency of the vitamin K–dependent clotting factors (VKCFDs), caused by a problem with clotting factors II, VII, IX, and X.
• Hemophilia A, a condition in which you are missing clotting factor VIII or have low levels of clotting factor VIII. Hemophilia A is the most common type of hemophilia.
• Hemophilia B, a condition in which you are missing clotting factor IX or have low levels of clotting factor IX.
• Hemophilia C, a rare condition also known as factor XI deficiency.
• Von Willebrand disease (VWD), the most common inherited bleeding disorder. The different types of VWD are numbered based on how common the condition is and how severe the symptoms are. For example, VWD 1 is the most common, and symptoms are usually mild, and VWD 3 is uncommon with symptoms that are usually severe.
• Other inherited bleeding disorders include other factor deficiencies, such as I, II, V, V + VIII, VII, X, XI, or XIII deficiencies. These rare bleeding disorders are named by the clotting factor causing the problem.
• Hereditary hemorrhagic telangiectasia is a rare inherited condition in which your blood vessels get tangled in different parts of the body, which can lead to bleeding.
