Heavy periodsDiagnosis

See a GP if you feel your periods are unusually heavy or have become heavier. They'll investigate the problem and may offer treatments to help.


Heavy periods are when you lose a lot of blood during your period or your periods last a long time.


You may have heavy periods if you lose a lot of blood during your periods, pass large blood clots or your periods last more than 7 days.


It's not always clear why some women get heavy periods. Sometimes it's linked to conditions like fibroids or endometriosis.


Common treatments for heavy periods include contraceptives and medicines to help reduce the amount of blood you lose.
