Which disease is characterized as a bleeding disorder in which the blood does not clot normally?

Haemophilia is accurately described as a bleeding disorder where the blood does not clot normally due to deficiencies in specific clotting factors. This genetic disorder predominantly affects males and leads to prolonged bleeding after injuries, surgeries, or even spontaneously, due to the inability of the blood to form effective clots. Patients with haemophilia often require treatments that involve clotting factor replacement to manage their condition and reduce the risk of bleeding complications.

In contrast, while anemia relates to a deficiency in red blood cells or hemoglobin, it does not inherently pertain to the clotting process. Hemorrhagic fever involves viral infections that can cause bleeding but is not classified as a primary bleeding disorder like haemophilia. Sickle cell disease is a genetic condition affecting the shape and function of red blood cells, which can lead to various complications, including painful crises, but it does not primarily stem from a malfunction in the clotting process. Thus, haemophilia stands out as the specific disorder characterized by the failure of normal blood clotting.
