Christmas Disease

Christmas disease, also known as hemophilia B, is an inherited clotting disorder in which factor IX, a protein essential for the blood to form clots, is missing or insufficient.

Common causes: It is passed on in an X-linked manner, so it mainly affects men, while women are usually carriers of the genetic alteration.

Frequent symptoms: Prolonged bleeding after wounds or procedures, frequent bruising, and, in more pronounced cases, bleeding into the joints or muscles that can cause pain and swelling.

Which specialist treats it? The hematologist is the one who studies and follows up on this type of disorder. When bleeding takes a long time to stop or recurs without explanation, seeing this professional helps better understand the situation.
