Hemorrhage refers to bleeding, which can be minor or severe and require different levels of medical treatment. Bleeding can be externalized or internal, affecting arteries, veins, capillaries, or the brain, and can be life-threatening if not treated promptly.
The term hemorrhage is used in the medical field to describe bleeding. Many different types of bleeding can occur, each requiring different levels of medical treatment.
The least worrisome hemorrhages are those characterized as minor traumatic bleeding. These result from minor wounds and the amount of blood loss is not considered dangerous. Also, the bleeding stops on its own without the need for medical intervention. The only area of concern is the possibility of an infection developing, which is a concern with all types of bleeding.
Severe traumatic bleeding is a greater cause for concern. With severe bleeding, a cloth used to cover the wound will soak up the blood within seconds. If the bleeding is not stopped and the wound is not treated, the person can die within minutes from blood loss.
Bleeding can also be classified as externalized bleeding. This is characterized by blood flowing from orifices found naturally on the body, such as the ears, nose, mouth, urethra, vagina, or anus. With these bleeds, the bleeding starts internally and is caused by disease or trauma. This is not the same as internal bleeding, however, which refers to bleeding that occurs inside the body and cannot be seen from the outside.
Common internal bleeding occurs in arteries, veins and capillaries. Those that affect the arteries, which are responsible for carrying oxygen-rich blood to the heart, are referred to as arterial bleeding. These bleedings are difficult to control and often life-threatening.
Internal bleeding that affects the veins, which returns blood to the heart, is called venous bleeding. These are easier to control than arterial bleeds, and although they require medical attention, they are not as serious arterial bleeds.
Bleeding from capillaries, the smallest vessels in the body, is usually easier to control than arterial and venous hemorrhages. However, the slow nature of bleeding from these vessels makes them highly susceptible to infection.
Brain hemorrhages are another form of internal bleeding. With this type of bleeding, blood can pool in the spaces between the brain and its membranes or within the brain tissue. These hemorrhages can affect one part of the brain or be localized in only one hemisphere. If not treated properly and immediately, they can be fatal or cause permanent damage.
