Heavy Menstrual Bleeding in Fibroids?

Heavy Menstrual Bleeding in Fibroids?

Heavy bleeding (menorhagia) may involve

  • flooding (a sudden gush of blood)
  • long periods (a menstrual period typically lasts 4-5 days; women with fibroids often have longer periods, which may last 7 or more days)
  • passing large clots of blood

These periods may be unusually heavy, sometimes requiring a woman to change her pad hourly.


Heavy bleeding is not always due to fibroids, but when it is, it is usually associated with fibroids that grow into the womb (submucous).

Although it is unclear exactly why fibroids cause bleeding, it may be that fibroids stretch the lining of the womb and creating more lining to be shed during a period.


In addition to the inconvenience, heavy bleeding may also cause anemia and fatigue.


Bleeding between periods is not usually a sign of fibroids; however, women who experience this problem should check with their doctor.


If you are experiencing heavy bleeding for an extended length of time, talk to your doctor about treating your fibroids.

Anaemia (iron deficiency)

Some women with fibroids and heavy bleeding develop anaemia as a result of blood loss.
Anaemia can make you feel weak, dizzy and tired.
