Hemophilia is a rare genetic disorder that impairs the body's ability to make blood clots, a process needed to stop bleeding. This results in prolonged bleeding after an injury, easy bruising, and an increased risk of bleeding inside joints or the brain. Hemophilia is typically classified into two main types: Hemophilia A, which is a deficiency in clotting factor VIII, and Hemophilia B, which is a deficiency in clotting factor IX.
