Hemophilia is a hereditary bleeding disorder that prevents blood from clotting normally. Typical symptoms of this disease include frequent bruising, hematuria (blood in urine), excessive bleeding from small cuts, joint inflammation and pain, and nosebleeds. Depending on which clotting factor is lacking in your blood, the condition is diagnosed as Hemophilia A (the most common), Hemophilia B or Hemophilia C. Beyond heredity, some risk factors for acquiring Hemophilia include blood cancers like leukemia, kidney failure, autoimmune disease, liver disease, Vitamin K deficiency, chemotherapy and radiation therapy, and immune system deficiencies.
