Overview. Menorrhagia is the medical term for menstrual periods with abnormally heavy or prolonged bleeding. Although heavy menstrual bleeding is a common concern, most women don't experience blood loss severe enough to be defined as menorrhagia.

What is considered profuse bleeding?

If you need to change your tampon or pad after less than 2 hours or you pass clots the size of a quarter or larger, that is heavy bleeding. If you have this type of bleeding, you should see a doctor. Untreated heavy or prolonged bleeding can stop you from living your life to the fullest. It also can cause anemia.

How much bleeding is too much during period?

Heavy for 1 woman may be normal for another. Most women will lose less than 16 teaspoons of blood (80ml) during their period, with the average being around 6 to 8 teaspoons. Heavy menstrual bleeding is defined as losing 80ml or more in each period, having periods that last longer than 7 days, or both.
