Iron deficiency is one of the most widespread nutritional deficiencies globally, affecting around 10-15% of people in the U.S. Women are at a higher risk than men due to blood loss during menstruation. Despite its common occurrence, many symptoms of iron deficiency are subtle and frequently overlooked. Identifying these early signs can help prevent more severe health issues.

Common Causes of Low Iron Levels
Low iron levels can stem from insufficient dietary intake, heavy menstrual periods, pregnancy, or the body’s inability to absorb enough iron from food. Approximately one-third of women experience heavy menstrual bleeding, which raises their risk of iron deficiency. Additionally, lifestyle factors like intense exercise, vegetarian or vegan diets, and frequent blood donation can also contribute to reduced iron levels.
Fatigue and Weakness: Early Indicators
One of the earliest signs of iron deficiency is often persistent fatigue. Iron plays a crucial role in transporting oxygen in the blood, and when levels are low, the body struggles to produce sufficient hemoglobin. This compromises oxygen delivery to tissues and muscles, resulting in chronic fatigue and muscle weakness. If you consistently feel exhausted despite getting enough rest, it could be an indication of iron deficiency.
Pale Skin and Brittle Nails: Physical Signs
Iron deficiency lowers hemoglobin levels, which can result in paler skin, especially noticeable in the face, inner eyelids, and nails. It may also cause the tongue to appear pale. Additionally, brittle nails, known as koilonychia, can develop, where nails become thin, concave, and develop noticeable ridges. If your nails are prone to breaking or have an unusual shape, it could be a sign of iron deficiency, and checking your iron levels may be advisable.
Shortness of Breath and Dizziness
Iron deficiency impairs the oxygen-carrying capacity of red blood cells, making even simple activities, such as climbing stairs or walking short distances, feel exhausting. It can also lead to frequent dizziness or lightheadedness, as the brain may not receive enough oxygen. If you often feel breathless during routine activities, it could be a sign of low iron levels.
Unusual Cravings and Pica
A lesser-known symptom of iron deficiency is pica, a condition characterized by cravings for non-food items like ice, dirt, chalk, or paper. While the exact cause of pica remains unclear, some researchers suggest it may be the body’s way of signaling a nutrient deficiency. If you experience cravings for unusual substances, itโs important to consult a healthcare provider to assess your iron levels.
Hair Loss and Thinning
While hair loss can stem from various causes, iron deficiency is often a key factor. Iron is essential for cell growth and repair, including the health of hair follicles. When iron levels are low, hair can weaken and shed more easily. If youโre experiencing noticeable thinning or excessive hair loss, itโs worth considering whether low iron levels might be playing a role. Consulting a healthcare professional can help determine if iron deficiency is contributing to the issue.
Cold Hands and Feet
Iron is essential for regulating body temperature, and individuals with low iron levels often experience cold hands and feet. This happens because reduced oxygen transport, caused by iron deficiency, can lead to poor circulation, leaving extremities feeling chilly even in warm environments. If you frequently find yourself unusually sensitive to the cold, it might be worth checking your iron levels to see if theyโre the underlying cause.
Restless Leg Syndrome
Restless Leg Syndrome (RLS) is a neurological condition characterized by an uncontrollable urge to move the legs, often accompanied by uncomfortable sensations like tingling or crawling. Research has connected RLS to iron deficiency, as iron is essential for dopamine productionโa neurotransmitter that helps regulate muscle movement. If you find yourself with an irresistible need to move your legs, particularly at night, it could be a sign of low iron levels. Consulting a healthcare professional to check your iron status may help address the underlying cause.
Rapid heartbeat and Anxiety
Iron deficiency doesnโt just take a toll on the bodyโit can also significantly impact mental health. Low iron levels have been linked to difficulty concentrating and mood disturbances, such as anxiety and depression. Since iron plays a crucial role in neurotransmitter function, insufficient levels can contribute to cognitive challenges and emotional imbalances.
Additionally, low iron can lead to chest palpitations and a rapid heartbeat, which, over time, can put extra strain on the heart. Addressing iron deficiency through proper diet, supplementation (with medical guidance), and lifestyle changes is essential for both physical and mental well-being. If youโre experiencing these symptoms, itโs important to consult a healthcare professional to check your iron levels and take steps to restore balance.
How to Address Iron Deficiency.
If you suspect iron deficiency, a blood test can confirm whether your levels are low. Treatment usually includes taking iron supplements and increasing your intake of iron-rich foods like lean meats, leafy greens, beans, and fortified cereals. To boost absorption, pair these foods with vitamin C sources, such as citrus fruits or bell peppers. Always consult your doctor before starting any supplementation.
By recognizing the early signs of iron deficiency and making proactive changes to your diet and lifestyle, you can improve your overall health and well-being. If youโre experiencing any of these symptoms, it may be time to check your iron levels and take steps to prevent long-term complications.
