Hemophilia B is a genetic disorder that affects the blood's ability to clot properly. It is caused by a deficiency of a specific protein called factor IX, which is essential for the clotting process. People with Hemophilia B may experience prolonged bleeding after injuries, surgeries, or even spontaneous bleeding episodes, particularly in joints and muscles. This condition is inherited, meaning it is passed down through families, primarily affecting males. Treatment often involves regular infusions of factor IX to help manage bleeding episodes and prevent complications. With proper care, individuals with Hemophilia B can lead active and fulfilling lives.
