Causes
Internal bleeding can occur by traumatic injury such as high speed deceleration in an automobile accident, or by blood vessel rupture from high blood pressure. Also, internal bleeding can be caused by hitting or running against a sharp object in that area. Some diseases may also cause internal bleeding, such as the Filovirus Ebola. This infection, together with similar infections such as the Marburg virus, is rare. The most common cause of internal bleeding is carcinoma (cancer), either of the gastro-intestinal tract or of the lung, or more rarely of other organs such as the prostate, pancreas or kidney. Other diseases linked to internal bleeding include scurvy, hepatoma, liver cancer, Autoimmune Thrombocytopenia, ectopic pregnancy, malignant hypothermia, ovarian cysts, Vitamin K Deficiency, and hemophilia. Some medication interactions may also cause internal bleeding.
