There are numerous different bleeding disorders, but the following are the most common ones:  

Hemophilia A and B are conditions that occur when there are low levels of clotting factors in your blood. It causes heavy or unusual bleeding into the joints. Though hemophilia is rare, it can have life-threatening complications.

Factor II, V, VII, X, or XII deficiencies are bleeding disorders related to blood clotting problems or abnormal bleeding problems.

Von Willebrand's disease is the most common inherited bleeding disorder. It develops when the blood lacks von Willebrand factor, which helps the blood to clot.

What causes a bleeding disorder?

Bleeding disorders often develop when the blood can’t clot properly. For blood to clot, your body needs blood proteins called clotting factors and blood cells called platelets. Normally, platelets clump together to form a plug at the site of a damaged or injured blood vessel. The clotting factors then come together to form a fibrin clot. This keeps the platelets in place and prevents blood from flowing out of the blood vessel.

In people with bleeding disorders, however, the clotting factors or platelets don’t work the way they should or are in short supply. When the blood doesn’t clot, excessive or prolonged bleeding can occur. It can also lead to spontaneous or sudden bleeding in the muscles, joints, or other parts of the body.

The majority of bleeding disorders are inherited, which means they’re passed from a parent to their child. However, some disorders may develop as a result of other medical conditions, such as liver disease.

Bleeding disorders may also be caused by:

a low red blood cell count

a vitamin K deficiency

side effects from certain medications

Medications that can interfere with the clotting of the blood are called anticoagulants.

How is a bleeding disorder diagnosed?

To diagnose a bleeding disorder, your doctor will ask you about your symptoms and medical history. They will also perform a physical examination. During your appointment, make sure to mention:

any medical conditions you currently have

any medications or supplements you may be taking

any recent falls or trauma

how often you experience the bleeding

how long the bleeding lasts

what you were doing before the bleeding began

After gathering this information, your doctor will run blood tests to make a proper diagnosis. These tests may include:

a complete blood count (CBC), which measures the amount of red and white blood cells in your body

a platelet aggregation test, which checks how well your platelets clump together

a bleeding time test, which determines how quickly your blood clots to prevent bleeding

How are bleeding disorders treated?

Treatment options vary depending on the type of bleeding disorder and its severity. Though treatments can’t cure bleeding disorders, they can help relieve the symptoms associated with certain disorders.

Iron supplementation

Your doctor may prescribe iron supplements to replenish the amount of iron in your body if you have significant blood loss. A low iron level can result in iron deficiency anemia. This condition can make you feel weak, tired, and dizzy. You may need a blood transfusion if symptoms don’t improve with iron supplementation.
