At a Glance
Many women experience heavy periods at some point in their lives. However, bleeding that is unusually heavy, lasts longer than seven days, or interferes with daily activities may be a sign of Heavy Menstrual Bleeding (HMB), sometimes called menorrhagia.
Heavy menstrual bleeding is common and can affect physical health, emotional wellbeing, work, education, and family life. It is also one of the leading causes of iron deficiency and anaemia in women.
The good news is that effective treatments are available. If your periods are affecting your quality of life, you do not have to simply "put up with it."
What is Heavy Menstrual Bleeding?
Heavy menstrual bleeding means losing more blood during your period than is considered normal.
You may have heavy menstrual bleeding if you:
Bleed for longer than seven days.
Need to change pads or tampons every one to two hours.
Pass large blood clots.
Need to use two forms of protection at the same time.
Wake during the night to change sanitary products.
Find your period affects work, school, or daily activities.
Heavy bleeding is not always caused by a serious condition, but it should always be discussed with a healthcare professional if it is persistent.
Why It Matters for Black African Women
Heavy menstrual bleeding is particularly important because it can contribute to several health challenges that disproportionately affect Black African women.
These include:
Iron deficiency
Anaemia
Uterine fibroids
Pregnancy complications
Delayed diagnosis due to stigma
Limited access to specialist care
Cultural beliefs that normalise excessive bleeding
Many women assume that extremely heavy periods are simply "normal" because other family members experience them. In reality, heavy bleeding is often treatable.

Soaking through sanitary protection every one to two hours.
