4. Abnormally large bruises.
It’s normal for people to experience bruises from time-to-time, and depending on the severity of the injury, bruises can be extremely large. However, in individuals who lack clotting factors in their blood, excessive contusions can develop even after sustaining a minor bump or fall.
Contusions occur when the body has experienced some sort of trauma, and that trauma causes the eruption of capillaries, which leads to blood getting trapped underneath the surface of the skin.
The blood that’s trapped under the skin creates the appearance of a dark bluish-purplish mark. Because a hemophiliacs blood is unable to effectively clot, their skin is often covered with bruises, as capillaries can burst underneath the skin even after a minor abrasion that would cause a slight bruise, if any bruise at all, in someone who possesses adequate levels of Factor VII and Factor X proteins in their blood.
