In the relentless pace of modern life, persistent tiredness is often dismissed as an inevitable byproduct of being busy. For millions of women, however, this constant fatigue, the kind that isn’t remedied by a full night’s sleep, may be a crucial warning sign of a common yet frequently overlooked condition: iron deficiency anaemia. ITV regular and NHS GP Dr. Amir Khan highlights this issue, noting that it is “so common” for women at or around perimenopausal age to develop anaemia due to blood loss from their periods. This biological reality means that the very rhythm of a woman’s body can gradually deplete its iron stores, turning daily vitality into a struggle. Ignoring these signs, chalking them up to mere lifestyle demands, can be a dangerous oversight, potentially leading to significant harm over time.
The symptoms of iron deficiency anaemia extend beyond profound tiredness. Dr. Khan explains that because iron is essential for a robust immune system, recurring infections can also serve as a red flag. Other tell-tale signs often include headaches, unusual paleness, shortness of breath, and noticeable heart palpitations. A rarer but telling indicator is restless leg syndrome—an overpowering urge to move the legs, particularly in the evening. These symptoms collectively paint a picture of a body struggling to transport oxygen efficiently. The condition stems from a lack of iron, a mineral crucial for producing haemoglobin in red blood cells. When levels are low, every system in the body can be affected, from energy production to immune defence.
The risks of leaving iron deficiency anaemia untreated are serious and multifaceted. It can heighten susceptibility to illness and infection, placing a constant strain on overall health. In the long term, it may increase the risk of complications affecting the heart and lungs, as these organs work harder to compensate for the lack of oxygen in the blood. For pregnant women, the stakes are even higher, as untreated anaemia poses greater risks of complications both before and after birth. Given that heavy periods and pregnancy are among the most common causes, this is not a niche concern but a widespread health issue affecting billions globally to varying degrees. Recognising the symptoms is the first, vital step toward reclaiming health.
Diagnosis is straightforward and accessible. A simple blood test ordered by a GP can confirm iron deficiency anaemia, and the doctor will likely inquire about medical history and lifestyle to identify the underlying cause. Once diagnosed, treatment is typically very effective. Doctors usually prescribe iron tablets, which may need to be taken for around six months to replenish the body’s stores fully. Throughout this period, follow-up blood tests will monitor progress to ensure iron levels are returning to normal. The goal is not just to treat the anaemia but to address its root cause, whether that’s related to menstrual blood loss, dietary intake, or another medical factor.
Alongside supplementation, diet plays a foundational role in both treatment and prevention. Since the human body cannot produce its own iron, we must obtain it from our food. The recommended daily intake varies; women aged 19 to 49 need approximately 14.8mg (to offset menstrual losses), while men over 19 and women over 50 require 8.7mg. Incorporating iron-rich foods is key. Excellent sources include dark leafy greens like kale, red meats, pulses such as lentils and chickpeas, fortified cereals, and dried fruits like apricots. Simultaneously, it’s helpful to be mindful that substances like tea, coffee, and foods high in phytic acid (found in wholegrains) can inhibit iron absorption, so consuming them separately from iron-rich meals or supplements can maximise benefit.
Ultimately, the message is one of empowerment through awareness. The fatigue that feels like a personal failing—a sign of not coping with a hectic life—is often a legitimate medical signal from your body. By listening to these cues and seeking a simple check-up, women can uncover a treatable condition, restoring their energy and safeguarding their long-term health. In a world that often expects constant productivity, prioritising this aspect of self-care is not an indulgence but a critical investment in one’s wellbeing. If sleep no longer brings refreshment, it may be time to start a conversation with your doctor and turn that persistent tiredness into a catalyst for positive change.
