Bleed
Bleed (Medical Term)
Bleed (/bli:d/), from the Old English blēdan, is a medical term referring to the loss of blood from the circulatory system.
Definition
Bleeding, also known as a hemorrhage or haemorrhage, is blood escaping from the circulatory system from damaged blood vessels. Bleeding can occur internally, where blood leaks from blood vessels inside the body, or externally, either through a natural opening such as the mouth, nose, ear, urethra, vagina or anus, or through a wound in the skin.
Causes
Bleeding can be caused by a variety of factors, including physical trauma, medical conditions, and medical or surgical procedures. Some common causes include injury, surgery, menstruation, and hemophilia.
Types of Bleeding
There are several types of bleeding, including:
- Arterial Bleeding: This is when the blood is bright red and spurts out in time with the heart's contractions.
- Venous Bleeding: This is when the blood is dark red and flows out steadily.
- Capillary Bleeding: This is when the blood oozes out slowly.
Treatment
Treatment for bleeding depends on the location, severity, and cause of the bleeding. It may include first aid measures, medication, surgery, or a combination of these. Some common treatments include pressure bandages, hemostatic agents, and surgery.
