When a person is cut or begins to bleed, certain proteins called clotting factor help our bodies stop bleeding. Each protein plays a key role at a certain stage of the clotting process. People with bleeding disorders are missing one of these proteins, making clotting difficult. Bleeding disorder is a general term for a range of medical conditions that cause poor blood clotting and continuous bleeding because of the absence of one of these proteins. A bleeding disorder occurs when the body is unable to activate the entire “clotting cascade” correctly.
