Which hereditary condition causes abnormally slow blood clotting?

Hemophilia is a hereditary condition characterized by the absence or deficiency of specific clotting factors in the blood, which leads to abnormally slow blood clotting. This results in prolonged bleeding after injury, surgery, or sometimes even spontaneously without any obvious cause. The most common types of hemophilia are Hemophilia A, which involves a deficiency in factor VIII, and Hemophilia B, resulting from a deficiency in factor IX.

Individuals with hemophilia often experience symptoms such as easy bruising, excessive bleeding from minor cuts, and joint pain or swelling due to internal bleeding. The nature of this condition makes it vitally important for those affected to manage their health carefully and seek appropriate medical treatment, which may include infusions of the missing clotting factors.

In contrast, other conditions listed do not primarily affect blood clotting in this manner. For example, sickle cell anemia is a genetic disorder that affects the shape of red blood cells, leading to various complications, but it does not inherently cause slow blood clotting. Endometriosis is a condition involving the growth of endometrial tissue outside the uterus and does not pertain to blood clotting directly. Stage 4 anemia is a classification related to the severity of anemia but does
