It refers to the output or loss of blood from the inside of blood vessels in small amounts (<500cc). The bleeding can be arterial, venous or capillary and, according to its origin, internal (inside the body) or external (outside the body).
It can be caused by accidents, injuries, ulcers, varicose veins and other diseases.
Being a light bleeding, there might be no symptoms or that those are minimal, such as a state of anxiety and/or slight feeling of dizziness.
The diagnosis is made through the clinical questioning and physical examination. Depending on the origin of the bleeding, additional tests may or may not be required.
Depending on the type of bleeding, it must be assessed whether treatment can be performed at home with a simple direct compression at the bleeding point or it must be performed in a health centre or hospital as it may require bandages, sutures, antibiotic treatment and/or surgical treatment.
