how do you lose blood
There are lots of ways... if you have a cut or a scrape, or a larger wound you can lose blood. You can have internal bleeding, so that you are losing blood (it is pooling somewhere in your body rather than being pumped throughout). That can be caused by anything from a broken rib, a ruptured appendix, or hemorrhoids.
For reference, when a person donates blood, about eight to 10 percent of the bodyâs blood is removed. There are generally no symptoms of blood loss at this point, though some may feel slightly faint. A Class 2 hemorrhage is a loss of 15 to 30 percent of blood volume. This is where symptoms of blood loss begin to manifest. âThe body tries to compensate at this point with, among other things, a faster heartbeat to speed oxygen to tissues,â Alton said. âThe patient will feel weak, appear pale, and skin will be cool.â.
