Hemophilia is a rare disorder in which your blood doesn't clot normally because it lacks sufficient blood-clotting proteins (clotting factors). If you have hemophilia, you may bleed for a longer time after an injury than you would if your blood clotted normally.

Small cuts usually aren't much of a problem. The greater health concern is deep bleeding inside your body, especially in your knees, ankles and elbows. That internal bleeding can damage your organs and tissues, and may be life-threatening.

Hemophilia is an inherited (genetic) disorder. Treatment includes regular replacement of the specific clotting factor that is reduced.

Symptoms

Signs and symptoms of hemophilia vary, depending on your level of clotting factors. If your clotting-factor level is mildly reduced, you may bleed only after surgery or trauma. If your deficiency is severe, you may experience spontaneous bleeding.

Signs and symptoms of spontaneous bleeding include:

Unexplained and excessive bleeding from cuts or injuries, or after surgery or dental work

Many large or deep bruises

Unusual bleeding after vaccinations

Pain, swelling or tightness in your joints

Blood in your urine or stool

Nosebleeds without a known cause

In infants, unexplained irritability


Causes

When you bleed, your body normally pools blood cells together to form a clot to stop the bleeding. The clotting process is encouraged by certain blood particles. Hemophilia occurs when you have a deficiency in one of these clotting factors.

There are several types of hemophilia, and most forms are inherited. However, about 30 percent of people with hemophilia have no family history of the disorder. In these people, an unexpected change (spontaneous mutation) occurs in one of the genes associated with hemophilia.

Acquired hemophilia is a rare variety of the condition that occurs when a person's immune system attacks clotting factors in the blood. It can be associated with:

Pregnancy

Autoimmune conditions

Cancer

Multiple sclerosis
