Internal bleeding (also called internal hemorrhage) is a loss of blood that occurs from the vascular system into a body cavity or space. It is a serious medical emergency and the extent of severity depends on bleeding rate and location of the bleeding (e.g. heart, brain, stomach, lungs). It can cause death and cardiac arrest if proper medical treatment is not received quickly.
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.
