Hemophilia B is a rare genetic bleeding disorder occurs in patients who don’t produce adequate IX proteins, needed for blood clot formation to stop bleeding. This deficiency in factor IX clotting activity results in prolonged oozing after injuries, tooth extractions, or surgeries, and also may cause delayed or recurrent bleeding prior to wound healing.
Most patients with hemophilia are born with it, as the disease is almost always inherited (or passed down) from a parent to their child.
