Bleeding, hemorrhage, haemorrhage or blood loss, is blood escaping from the circulatory system from damaged blood vessels. Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, vagina, or anus, or through a puncture in the skin. Internal bleeding happens when your blood vessels break and blood collects inside your body.

Understanding the Context

There are several causes of internal bleeding that range in severity. Bleeding can be caused by injuries, or it can be spontaneous. Spontaneous bleeding most commonly occurs with problems in the joints, or gastrointestinal or urogenital tracts. Bruising or bleeding after an injury is normal (see also How Blood Clots).

Key Insights

However, some people have disorders that cause them to bruise or bleed too easily. Sometimes people bleed without any obvious triggering event or injury. Hemorrhage is the medical term for any type of internal or external bleeding. You need medical treatment, such as blood transfusions or surgery, for severe bleeding.
