Why is it that you don't die from having your period? I know you can die from loosing blood anywhere else, by why don't you when you have your period? If you cut your arm and let it bleed that much for how ever long your period is, you'd die, but when you have your period you don't. How is this possible?
Research has shown that the average period blood loss is 40-60 mls (8-12 teaspoonfuls). Some women may complain of excess loss when they are only losing less than 10mls.
Some women losing up to 400 mls do not realize that they have a problem (500mls is about a pint, the amount given when someone donates blood), which for a menstrual cycle, is very heavy. A physician should be contacted if this is the case.
