Internal bleeding facts
- Internal bleeding may occur in many areas of the body and may cause
significant local inflammation and pain. If enough bleeding occurs, signs of shock may be
apparent.
- Bleeding is a recognized complication of anti-coagulation and
anti-platelet medications. The benefits of taking these medications need
to be balanced against the risk of bleeding.
- Bleeding is never normal in
pregnancy.
- If internal bleeding is suspected, it is important to seek medical care.
What is internal bleeding?
While the general public understands that internal bleeding means
bleeding that can't be seen on the outside of the body, medical
personnel tend to use terms that describe more precisely the location
inside the body where the bleeding is found. The internal bleeding may
occur within tissues, organs, or in cavities of the body including the
head, spinal canal, chest, and abdomen. Examples of other potential
sites of bleeding include the eye and within tissues that line the
heart, muscles, and joints.
Bleeding outside the body is quite easy to recognize. If the skin is damaged by a laceration, puncture, or abrasion, blood can be witnessed as it streams out of the body. The scalp and face have a very rich blood supply and are notorious for demonstrating massive blood loss.
Internal bleeding may be much more difficult to identify. It may not be
evident for many hours after it begins, and symptoms may only occur when
there is significant blood loss or if a blood clot is large enough to compress an organ and prevent it from functioning properly.
Internal bleeding occurs when damage to an artery or vein allows blood to escape the circulatory system and
collect inside the body. The amount of bleeding depends upon the amount
of damage to an organ, the blood vessels that supply it, and the body's
ability to repair breaks in the walls of the blood vessels. The repair
mechanisms available include both the blood clotting system and the
ability of blood vessels to go into spasm to decrease blood flow to an
injured area.
People who take blood-thinning or anti-clotting medication are more
prone to bleeding than people who do not take these medications. These
individuals may experience significant bleeding even with relatively
minor injury or illness, and the risk of bleeding needs to be balanced
against the benefits of taking the medication. A variety of "blood
thinning" medications are now prescribed for many diseases.
