What Counts as "Heavy"?
Medically, heavy menstrual bleeding (HMB) is defined as blood loss exceeding 80ml per cycle, but few women measure this. More practically, if you're soaking through a pad or tampon every hour for several consecutive hours, passing clots larger than a 50p coin, or your bleeding significantly impacts daily life, that qualifies as heavy and deserves investigation.
Why Women Wait
Research shows the average woman waits 4–7 years before seeking help for heavy periods. The reasons are heartbreaking and familiar: being told it's "just your normal," internalising the idea that periods are supposed to be painful, or feeling dismissed during previous appointments. Heavy periods are not something you should simply endure.
What to Say in the Appointment
Come prepared with specifics: how many products you use per day, whether you flood or leak, whether you pass clots, how many days your period lasts, and how much it affects your work, exercise, sleep, or relationships. Ask specifically for a full blood count to check for anaemia, a pelvic ultrasound to rule out fibroids or polyps, and thyroid function tests. Say clearly: "This is impacting my quality of life and I want it investigated."
Common Causes Worth Investigating
Heavy periods are frequently caused by fibroids (present in up to 70% of women by age 50), endometrial polyps, adenomyosis, thyroid disorders, von Willebrand disease (an underdiagnosed bleeding disorder in women), or hormonal imbalances like PCOS. All of these are treatable. You deserve a diagnosis, not just period pain killers.
