Scientists think they might have finally found an explanation for why more than one-third of women experience heavy periods each month.
Rather than being related to hormones, a new small study suggests that low levels of a specific protein in the uterus might be to blame.
While most women lose up to 40 millilitres of blood each period, around 30 percent of women will lose as much as 80 millilitres - or more than a quarter of a cup - at least one cycle throughout their life.
That might not sound like a whole lot, but, trust me, it’s definitely noticeable when you’re running around trying to get on with work, school, and generally live life.
Sometimes this heavy bleeding is caused by a physical problem - such as fibroids or endometriosis - but around half the time, doctors have no idea what’s going on, or how to stop it.
University of Edinburgh researchers say they’ve now found early evidence that a protein called HIF1, or hypoxia-inducible factor 1, might be linked to heavy bleeding.
