Common Iron Deficiency Symptoms in Women
Iron deficiency in women, whether or not it leads to anemia, is very common and can cause a wide range of symptoms. The most frequently reported symptoms include fatigue, poor concentration, reduced work function, increased susceptibility to infections, cardiovascular stress, pica (craving for non-food items like ice), restless legs syndrome, hair loss, brittle nails, and poor mental health, including symptoms like low mood and anxiety Moisidis-Tesch2022Fernández-Jiménez2020Dugan2021+3 MORE. Many women experience two or more of these symptoms at the same time .
Fatigue, Cognitive, and Mental Health Symptoms
Fatigue is one of the most common and debilitating symptoms of iron deficiency in women, including during pregnancy, and is often mistakenly attributed to normal life or pregnancy changes Moisidis-Tesch2022Fein2024Benson2022+1 MORE. Iron deficiency can also cause problems with concentration, memory, and executive function, leading to issues like "brain fog" and poor work or school performance Fernández-Jiménez2020Dugan2021Munro2023+1 MORE. Studies have shown that iron therapy can improve cognitive function and working memory in women with iron deficiency .
Iron deficiency is also linked to mental health symptoms such as low mood, anxiety, restlessness, and even depressive symptoms. Treating iron deficiency can help improve these psychiatric symptoms, and sometimes iron deficiency is misdiagnosed as depression Ciulei2023Arshad2023.
Physical Symptoms: Pica, Restless Legs, Hair Loss, and More
Physical symptoms of iron deficiency in women include pica (especially craving ice), restless legs syndrome, diffuse hair loss, brittle or spoon-shaped nails (ungual changes), and cheilitis (inflammation at the corners of the mouth) Moisidis-Tesch2022Fernández-Jiménez2020Dugan2021+1 MORE. These symptoms can be distressing and impact daily life. Many of these symptoms, such as pica, cheilitis, and restless legs syndrome, often resolve with iron therapy, while hair loss and nail changes also improve significantly .
Causes and Risk Factors in Women
The main causes of iron deficiency in women are heavy menstrual bleeding, pregnancy, poor dietary iron intake, and poor absorption due to gut disorders or surgery Moisidis-Tesch2022Dugan2021Benson2022+2 MORE. Heavy menstrual bleeding is the most common cause in women of reproductive age, and both heavy bleeding and iron deficiency are often normalized or overlooked by society and healthcare providers Dugan2021Munro2023Maclean2023.
Iron Deficiency in Pregnancy
Iron deficiency is extremely common in pregnancy, affecting up to 90% of pregnant women in some studies Fein2024Benson2022. Fatigue is especially common in pregnant women with iron deficiency, even if they do not have anemia Fein2024Benson2022. Iron deficiency during pregnancy can also increase the risk of complications for both mother and baby, including preterm labor, low birth weight, and developmental issues in the child Benson2022Munro2023.
Impact on Quality of Life
Iron deficiency significantly reduces quality of life for women, causing daily symptoms that can interfere with work, school, and family responsibilities Moisidis-Tesch2022Fernández-Jiménez2020Dugan2021+2 MORE. The effects on cognitive function and mental health can lead to absenteeism and reduced productivity .
Conclusion
Iron deficiency in women is common and can cause a wide range of symptoms, including fatigue, cognitive and mental health issues, pica, restless legs, hair loss, and more. These symptoms can greatly impact quality of life but often improve with iron therapy. Heavy menstrual bleeding and pregnancy are major risk factors, and iron deficiency is frequently underdiagnosed and undertreated. Increased awareness and routine screening for iron deficiency in women, especially those with symptoms or risk factors, are essential for improving health and wellbeing Moisidis-Tesch2022Fernández-Jiménez2020Dugan2021+5 MORE.
