Hemophilia is a genetic blood disorder characterized by a deficiency or absence of certain proteins called clotting factors, which are essential for blood clotting. The two most common types are hemophilia A and hemophilia B, which result from deficiencies of clotting factor VIII and clotting factor IX, respectively. People with hemophilia can experience prolonged bleeding episodes, even from minor injuries or internal bleeding without apparent cause. Symptoms may include easy bruising, excessive bleeding from cuts or injuries, and spontaneous bleeding into joints or muscles, leading to pain and swelling. Treatment typically involves replacing the missing clotting factor through infusions, which can help control bleeding and prevent complications. With appropriate medical management and careful monitoring, people with hemophilia can lead relatively normal lives, although they require ongoing care to manage their condition effectively.
