The new research, carried out at the University of Edinburgh suggested the connection was due to increased inflammation in the womb lining. Such inflammation was observed in women having a higher Body Mass Index (BMI).
Up to 1 in 3 women experience very heavy periods at some point in their lives and can be so heavy they leak through their menstrual protection, while in extreme cases they can even require a blood transfusion. But the cause has never been understood.
The study leader, Dr Jacqueline Maybin said “Our findings suggest that women with obesity may experience heavier periods due to increased local inflammation and delayed repair of their womb lining.”
While additional, larger studies are needed before medical authorities can make strong recommendations, it’s a promising lead for sufferers and their doctors who may look at using anti-inflammatory medications, along with weight loss advice, to help treat heavy periods.
