Bleeding is a common symptom of injury and can range from minor to severe, potentially leading to [[shock]] or even death if not properly managed.

==Types of Bleeding==
Bleeding is classified into several types based on its source and characteristics:

* '''[[External bleeding]]''': Visible bleeding from an external wound. It can be further categorized into arterial, venous, or capillary bleeding, depending on the type of blood vessel that is damaged.
* '''[[Internal bleeding]]''': Occurs when blood leaks from blood vessels within the body into internal spaces or cavities. It can result from trauma, medical conditions, or medications and may not be immediately apparent.
* '''[[Capillary bleeding]]''': The most common and least severe type, involving the smallest blood vessels, the capillaries. It usually results in a slow, oozing flow of blood.
* '''[[Venous bleeding]]''': Involves loss of blood from a vein. It is characterized by a steady flow of dark red blood.
* '''[[Arterial bleeding]]''': The most serious type of external bleeding, involving loss of blood from an artery. It is recognized by a pulsating flow of bright red blood and can lead to rapid blood loss.

==Causes==
Bleeding can be caused by a variety of factors, including:

* [[Physical trauma]]: Such as cuts, abrasions, or blunt force injuries.

* Applying direct pressure to the wound with a clean cloth or bandage.
* Elevating the injured area above the level of the heart, if possible, to reduce blood flow.

* Managing anticoagulant medications carefully under the guidance of a healthcare provider.
* Regular monitoring and treatment of medical conditions that affect blood clotting.
