What are the symptoms of hemophilia?

Symptoms of hemophilia include prolonged oozing after injuries, tooth extractions or surgery; renewed bleeding after initial bleeding has stopped; easy or spontaneous bruising; and prolonged bleeding.

In both severe hemophilia A and severe hemophilia B, the most frequent symptom is spontaneous joint bleeding. Other serious sites of bleeding include the bowel, the brain and soft tissues. These types of bleeding can lead to throwing up blood or passing blood in the stool, stroke, and sudden severe pain in the joints or limbs. Painful bleeding into the soft tissues of the arms and legs can lead to nerve damage.

Individuals who have severe hemophilia are usually diagnosed within the first year of life. People who have moderate hemophilia do not usually have spontaneous bleeding, but they do have longer bleeding and oozing after small injuries. They are usually diagnosed before they reach five or six years.

Individuals who have mild hemophilia do not have spontaneous bleeding. If they are not treated they may have longer bleeding when they have surgery, teeth removed or major injuries. Individuals with mild hemophilia may not be diagnosed until later in life.
