Hemophilia is an inherited condition in which your child's blood doesn't clot normally. Children with hemophilia don't stop bleeding as quickly as other children and may have serious bleeding problems. When a person is injured or has surgery, platelets and clotting factors in the blood work together to help stop the bleeding and begin the process of healing. People with hemophilia A lack clotting factor 8. People with hemophilia B have little or no clotting factor 9.Symptoms of hemophilia vary depending on the type and severity of hemophilia. Some children with mild hemophilia (factor levels of 5-50% of normal) do not have symptoms until they have surgery, an accident, or a dental procedure. Those with moderate or severe hemophilia (factor levels of 1-5% of normal) may have symptoms of external and/or internal bleeding that begin shortly after birth. It is important that children with hemophilia and their families be aware of the signs and symptoms of bleeding and that treatment be administered as soon as possible.

The Center for Bleeding and Clotting Disorders

The Center for Bleeding and Clotting Disorders provides a complete range of care for children and adolescents with bleeding and thrombotic (clotting) disorders. Children's Minnesota belongs to a nationwide network of federally funded Hemophilia Treatment Centers (HTCs) and is the only such program in the region focused solely on pediatrics. This designation ensures that children and adolescents receive comprehensive care from a team of pediatric experts in bleeding and clotting disorders.
