3. Disease
The body creates proteins naturally that helps to clot the blood in the event of injury. Bleeding disorders such as von Willebrand disease and hemophilia prevent the proper production of these proteins which can cause internal bleeding that is difficult to treat. When there is too much clotting of the blood it leads to stroke or heart attack, while the inability to clot can cause excess bleeding or the inability to heal from internal bleeding.
Most blood-related diseases are almost exclusively inherited but in some very rare cases, they can develop spontaneously. These diseases develop as the body fights its own clotting factors which can result in chronic bouts of internal bleeding.
Bleeding disorders affect both men and women in equal amounts. Women who are pregnant and those with family members who have bleeding disorders are at the most risks of developing life-threatening instances of internal bleeding.
