The blood is not able to clot (stop bleeding) as well as it should.
There are three common types; Type A, Type B, and Type C.
Type A is the most common.
Type B is also known as the "Christmas disease."
What causes it?
It can be caused by congenital defects, or birth defects (problems in a
baby's growth and development before birth).
It often results because important things (such as proteins) are missing
from the blood to help it clot.
It can be inherited (passed from parent to child through genes).
Who can get it?
Type A and B are most common in men.
If a parent has hemophilia, their child is more likely to have hemophilia.
What are the signs and symptoms?
Patients may bleed anywhere.
They do not usually bleed large amounts from small cuts and wounds.
Bleeding is usually caused by more serious injuries, trauma, or surgery.
Patients may bleed into their joints (usually the elbows, ankles, knees,
or shoulders).
The joint may become warm, painful, and swollen. It may be difficult to
move.
Bleeding into the joints can cause joint damage.
Patients can also bleed into muscles, into the esophagus, or into the stomach
or intestine.
There may also be bleeding from the nose and gums.
Heavy menstrual bleeding is common in women.
There may be blood in the urine or stool.
It is possible to bleed into the brain, although this is not common. Other
symptoms usually include nausea, headache, and confusion.
The amount of bleeding varies from person to person.
Is it contagious?
No. It is not contagious.
How is it diagnosed and treated?
Doctors can test unborn babies to see if they might have hemophilia.
Baby boys may be diagnosed after circumcision if parents notice a lot of
bleeding.
Parents may notice an unusual amount of bruises or bleeding following common
injuries. This is especially common as babies get older, are able to move
around more, and have more falls.
Some patients are not diagnosed until a serious injury, trauma, or surgery.
The doctor will want a family history and details about your child's symptoms.
Your child may need blood tests.
Patients may need to have blood products (like plasma) added to their blood.
This will help stop bleeding.
The doctor can use other people's blood products to put in your child's
blood. If your child is old enough, he may be able to learn how to do it himself.
Patients may need physical therapy if they have joint damage.
If your child gets a minor cut, cover the area with a bandage and add pressure.
For bruises, use an ice pack. Your doctor can give you other specific recommendations.
Tell teachers, childcare staff, relatives, and others who will watch your
child about his condition.
How long does it last?
It is a lifelong illness but symptoms can usually be controlled with proper
treatment.
Can it be prevented?
A parent with hemophilia or with a family history of hemophilia can talk
to a counselor to see what the risk is of having a child with it.
Prevent bleeding by avoiding injuries.
Parents should pad the baby's crib.
Exercise is encouraged. They should not participate in contact sports or
diving. Walking, swimming, and biking are okay. Talk to your doctor.
Some joint damage can be prevented if treatment is started early in life.
Patients should avoid taking aspirin and other medications that effect blood
clotting.
Patients should be immunized against the hepatitis A and B viruses.
When should I call the doctor?
Call the doctor if your child has hemophilia and is bleeding a large amount,
especially if the injury involves the head or neck.
Call the doctor if the child has sudden pain, swelling, and warmth in the
joints.
Call the doctor if your child has many bruises or lots of bleeding following
minor injuries.
If you are pregnant and have a family history of hemophilia, call your doctor.
Call the doctor if your child has symptoms of hemophilia.
Call the doctor if you have questions or concerns about your child's treatment
or condition.
