Signs and Symptoms
of Hemophilia

The major signs and symptoms of hemophilia are excessive bleeding and easy bruising.

Excessive Bleeding

The extent of bleeding depends on the type and severity of the hemophilia. Children with mild hemophilia may not have symptoms until they have excessive bleeding from a dental procedure, an accident, or surgery. Males with severe hemophilia may bleed heavily after circumcision. Bleeding can be obvious (external bleeding) or hidden within the body (internal bleeding).

Signs of excessive external bleeding include:

• Bleeding in the mouth from a cut or bite or from cutting or losing a tooth
• Nose bleeds for no obvious reason
• Heavy bleeding from a minor cut
• Bleeding from a cut that resumes after stopping for a short time

Signs of internal bleeding include blood in the urine (from bleeding in the kidneys or bladder) and blood in the stool (from bleeding in the intestines or stomach).

Bleeding in the Joints

Bleeding in the knees, elbows, or other joints is another common form of internal bleeding in people with hemophilia. This can occur without obvious injury. At first, this bleeding causes tightness in the joint with no real pain or any visible signs of bleeding. The joint then becomes swollen, hot to touch, and painful to bend.

Swelling continues as bleeding continues, and eventually movement in the joint is temporarily lost. Pain can be severe. Joint bleeding that isn’t quickly treated can permanently damage the joint.

Bleeding in the Brain

Internal bleeding in the brain is a very serious complication of hemophilia that can happen after a simple bump on the head or a more serious injury. The signs and symptoms of bleeding in the brain include:

• Long-lasting painful headaches or neck pain or stiffness
• Repeated vomiting
• Changes in behavior or being very sleepy
• Sudden weakness or clumsiness of the arms or legs or difficulty walking
• Double vision
• Convulsions or seizures
