Emma Cleary's life was forever altered by a seemingly 'hidden' health issue that affected her daily life. From her early teens, she suffered from light-headedness, extreme tiredness, and was nicknamed 'Casper' by classmates due to her ghost-like appearance. Despite repeated visits to her GP, her heavy periods and associated symptoms were never addressed, and the iron supplements she was prescribed did little to ease her symptoms. By her late 20s, the impact became impossible to ignore when her hair began falling out, and she even fainted in a supermarket due to heavy bleeding. Now 42 and a mother of two, Emma has finally found relief with a simple pill, tranexamic acid, and annual iron infusions. But her story is not unique; research suggests that one in three women suffer from heavy menstrual bleeding, and many do not even realize they are affected. Experts say this amounts to a 'silent public health crisis', and call for national screening for iron deficiency to prevent ill health and tackle inequalities. The condition, known as menorrhagia, can be treated with hormonal contraceptives or tranexamic acid, but prolonged heavy bleeding frequently leads to iron deficiency. Studies suggest that 36 per cent of UK women of child-bearing age may be iron-deficient, yet only one in four is formally diagnosed. Iron is an essential mineral, vital for energy levels, cognitive function, digestion, and immunity. While most people get sufficient amounts from food, heavy periods can quickly outweigh intake. Emma's story highlights the need for better awareness and management of heavy menstrual bleeding, and the importance of addressing the underlying health issues that affect so many women.
