ETYM Latin haemorrhagia, Greek aimorragia; aima blood + rhgnynai to break, burst: cf. French hémorragie, hémorrhagie.
(Alternate spelling: haemorrhage).
1. Any discharge of blood from the blood vessels, especially a sudden loss of blood.
2. Any sudden loss of an essential substance.
Discharge of blood.
Loss of blood from the circulatory system. It is “manifest” when the blood can be seen, as when it flows from a wound, and “occult” when the bleeding is internal, as from an ulcer or internal injury.
Rapid, profuse hemorrhage causes shock and may prove fatal if the circulating volume cannot be replaced in time. Slow, sustained bleeding may lead to anemia. Arterial bleeding is potentially more serious than blood lost from a vein. It may be stemmed by pressure above the wound, as by tourniquet.
1. To suffer a hemorrhage; to suffer a sudden loss of blood.
2. To suffer the sudden loss of any essential substance.
