Hemophilia is a rare, but serious blood disorder that prevents the blood from clotting properly following a scrape, cut or other injury. A lack of adequate clotting factor makes it difficult or even impossible for platelets to form clots and heal an injury. The condition can be mild, moderate or severe depending on the amount of clotting factor present in the body.
In most cases, hemophilia is acquired genetically and is passed from parent to child; although it is possible to acquire hemophilia at any point in life without a genetic predisposition. Symptoms include excessive bleeding, frequent nosebleeds, large bruises and blood in the urine or stool. Hemophilia is usually treated with clotting factor replacement therapy either when cuts and scrapes occur or as a preventive measure.
