Iron deficiency and anaemia quietly drain the energy of millions of women worldwide, causing tiredness, brittle nails, hair loss, and mood swings. Many women mistake these signs for just being busy or stressed, but the real culprit often lies in low iron levels from heavy periods, diets, or intense exercise. Sadly, these symptoms are often ignored or misunderstood, leaving women feeling worn out and foggy. With proper testing and treatment—like supplements or iron infusions—women can reclaim their strength and brighten their days. It’s time to listen, act, and bring this hidden health crisis into the light.
Iron deficiency and anaemia in women cause fatigue, brittle nails, hair thinning, mood swings, and brain fog. Common causes include heavy menstrual bleeding, poor diet, intense exercise, and plant-based diets. Early diagnosis through blood tests and proper treatment, including supplements or iron infusions, are essential.
Across city cafés and home kitchens alike, women swap stories of persistent tiredness, lingering regardless of how much rest they get. For many, exhaustion has become a companion they drag from morning meetings to evening errands, a background hum they can’t shake. While some accept it as an unavoidable consequence of fast-paced living, an underlying health issue often drives these symptoms.
Women in their late twenties and beyond frequently share frustrations over fatigue, brittle nails, hair thinning, and restless nights. With society pushing the narrative that modern life is to blame, few take the next step to explore possible health causes. Friends and even healthcare providers can overlook these symptoms, chalking them up to stress or overcommitment, without considering what might be happening beneath the surface.
From the romanticized images of weary women in classic art to the modern “superwoman” trope, the struggles of female vitality have deep roots. But today’s epidemic of low iron levels and anaemia goes largely undiscussed, even as it quietly undermines the daily lives of hundreds of millions of women around the world.
Globally, iron deficiency and anaemia affect a staggering proportion of women. Recent studies estimate that around 539 million women between the ages of 15 and 49 live with some form of anaemia—close to one in three women worldwide. The numbers climb even higher in certain regions; for example, nearly 43 percent of women in Africa fall into this category. These statistics are more than just figures on a page—they represent real people facing daily challenges.
Karin Davidson, a champion for anaemia awareness and head of the Cape Town Infusion Centre, encounters women from all walks of life who report similar complaints. Whether in their 20s, 30s, or 40s, these women describe a shared experience: overwhelming fatigue, frequent anxiety, mood swings, and a sense that life is happening in slow motion. Their stories reveal a hidden crisis, one that is commonly dismissed or misunderstood by society at large.
Davidson emphasizes the danger of normalizing these symptoms. “Constant tiredness, anxiety, and feelings of disconnection aren’t just parts of being busy or modern,” she explains. “They’re often red flags for iron deficiency—an issue that can be prevented and treated with proper attention.”
Iron does more than keep blood healthy; it’s fundamental to many systems in the body. Most are aware that iron helps combat fatigue, but its influence reaches further, affecting neurotransmitter production—particularly serotonin. This brain chemical shapes mood, regulates sleep, and supports emotional balance. When iron dips, serotonin production falters, leading to increased risks of depression, anxiety, insomnia, and the infamous “brain fog” that disrupts concentration and memory.
Symptoms of low iron often blend into daily life, making them easy to ignore. Shortness of breath, heart palpitations, dizzy spells, and poor focus don’t always trigger alarm, yet they signal a body struggling to function. Heavy periods, which drain iron reserves month after month, are another commonly overlooked contributor. Research shows that almost half of women of reproductive age endure heavy menstrual bleeding, and as girls begin menstruating earlier, this problem only intensifies.
Iron deficiency doesn’t discriminate, but certain groups stand at higher risk. Working women may skip meals or settle for nutrient-poor snacks in the rush between commitments. Mental sharpness and productivity drop when iron reserves run low, impacting everything from decision-making to emotional resilience. Those following plant-based diets face another hurdle: the body absorbs iron from animal sources more efficiently than from plants. Despite their best efforts, vegetarians and vegans may find it nearly impossible to restore iron just through food.
The rise in women pursuing athletic goals also brings new challenges. Intense exercise increases iron requirements, and without careful planning, even the most health-conscious can slide into deficiency. This paradox—getting stronger while feeling weaker—can leave female athletes confused and frustrated.
Getting a proper diagnosis often proves challenging. Doctors sometimes wave off symptoms as stress or the strain of daily life, rather than looking deeper. Davidson urges women to persist: “If your concerns are dismissed, seek another opinion. A simple blood test can reveal if iron deficiency is to blame.” Unfortunately, many women never receive adequate screening, allowing their symptoms to persist unchecked.
For those diagnosed, oral iron supplements usually become the first step. These need to be taken regularly and combined with vitamin C-rich foods such as citrus fruits or peppers to maximize absorption. However, it takes several weeks to months to rebuild iron stores, and some women experience stomach discomfort or other side effects. In more severe cases, or when rapid improvement is required—such as during pregnancy or before surgery—intravenous iron infusions can be a game changer. These treatments, administered under medical supervision, often restore iron and haemoglobin levels quickly and are increasingly covered by insurance under certain conditions.
Women concerned about their risk should keep a close watch on their symptoms and menstrual cycles and request comprehensive iron panels from their healthcare providers. If initial feedback is unsatisfactory, it’s crucial not to settle. Registered dietitians can provide personalized support, ensuring nutritional needs are met without compromising personal choices.
Certain practical habits support iron health. Eat iron-rich foods like lean meats, lentils, or beans alongside foods high in vitamin C, while avoiding coffee and tea around iron-rich meals, as they can block absorption. Still, experts agree that once anaemia takes hold, dietary changes alone rarely suffice, and medical intervention becomes crucial.
Prevailing attitudes often downplay women’s complaints of tiredness or mental fog, tracing them back to nerves or “just being busy.” This mindset has roots in history, when doctors dismissed legitimate health concerns with vague labels. Sadly, this legacy endures, teaching women to tolerate symptoms rather than investigate causes.
Today’s world offers women more information and resources than ever before. Just as artists once broke free from the constraints of tradition, women can now challenge the expectation that low energy and diminished well-being are unavoidable. Advocating for proper care, seeking answers, and insisting on thorough evaluations are vital steps toward reclaiming health and vitality. The Cape Town Infusion Centre, and organizations like it, highlight an emerging awareness that women shouldn’t have to ration their energy or accept chronic fatigue as normal.
Both individuals and healthcare providers must take action. Women should track symptoms, push for comprehensive testing, and seek expert advice when needed. When doctors dismiss concerns, consulting another provider is not only justified—it’s necessary. Modern medicine offers effective solutions, from supplements to iron infusions, that allow women to reclaim their lives and pursue their ambitions with renewed vigor.
On a larger scale, the medical community and society must do better. Listening to women, acknowledging the prevalence of iron deficiency, and providing clear educational resources are essential. As more women speak up about their experiences, the time has come to treat iron deficiency and anaemia as central issues in women’s health—not as minor inconveniences, but as challenges that deserve serious attention and action.
Women with iron deficiency and anaemia often experience persistent fatigue, brittle nails, hair thinning or hair loss, mood swings, brain fog, shortness of breath, heart palpitations, and dizziness. Other symptoms may include poor concentration, restless nights, and anxiety. These signs are frequently mistaken for stress or busy lifestyles but may indicate underlying iron deficiency.
The main causes include heavy menstrual bleeding, poor dietary intake of iron, intense or prolonged exercise, and certain dietary patterns such as vegetarian or vegan diets where iron absorption is less efficient. Women in reproductive age are particularly vulnerable because of monthly blood loss. Additionally, skipping meals or consuming nutrient-poor foods can contribute to insufficient iron levels.
Diagnosis requires a blood test called a complete blood count (CBC) along with iron studies, including serum ferritin, serum iron, and total iron-binding capacity (TIBC). These tests help determine iron levels and assess whether anaemia is present. If symptoms persist but initial tests are normal, further evaluation by a healthcare professional is recommended.
Treatment typically starts with oral iron supplements, often combined with vitamin C-rich foods to enhance absorption. However, supplements may take weeks to months to restore iron stores and can cause gastrointestinal side effects. In more severe cases or when rapid correction is needed (e.g., pregnancy or surgery), intravenous iron infusions may be recommended. Dietary improvements and addressing underlying causes, like heavy periods, are also important.
While eating iron-rich foods such as lean meats, lentils, beans, and pairing them with vitamin C sources helps improve iron absorption, diet alone often isn’t enough once anaemia develops. Plant-based diets tend to provide non-heme iron, which the body absorbs less efficiently than heme iron from animal sources. Therefore, supplementation or medical treatment may be necessary to fully restore iron levels.
Iron deficiency symptoms are frequently attributed to stress, busy lifestyles, or emotional issues rather than investigated medically. This dismissal can delay diagnosis and treatment. Women are encouraged to advocate for themselves by tracking symptoms, requesting comprehensive iron tests, and seeking second opinions if concerns are not taken seriously. Awareness and self-advocacy are vital to overcoming this hidden health crisis.
