Empower Your Health: Recognizing Signs of Iron Deficiency in Women and Taking Action
iron deficiency is the most common nutritional deficiency worldwide, and women are disproportionately affected. monthly blood loss through menstruation, the increased demands of pregnancy, and the nutritional shifts of perimenopause all create conditions where iron levels can drop below what the body needs to function optimally — often without a woman knowing why she feels the way she feels.
signs of iron deficiency to know
persistent fatigue. the most common symptom. iron is essential for haemoglobin production, which carries oxygen to every cell in the body. when iron is low, tissues are oxygen-deprived. the result is a tiredness that does not resolve with sleep — a baseline depletion that colours everything.
pale skin and nail beds. reduced haemoglobin shows in the skin. if the inside of your lower eyelids, your gums, or your nail beds appear unusually pale, low iron is worth investigating.
shortness of breath on exertion. breathlessness from activities that wouldn’t previously have left you winded — climbing stairs, a brisk walk — can indicate the body is struggling to deliver adequate oxygen.
heart palpitations. the heart compensating for reduced oxygen delivery by beating faster or irregularly. not always alarming in isolation, but worth noting alongside other symptoms.
hair thinning or loss. hair follicles are sensitive to nutritional deficiency. iron deficiency is one of the most common causes of diffuse hair thinning in women, and one of the most commonly missed.
cold hands and feet. poor peripheral circulation as the body prioritises oxygen delivery to vital organs.
brain fog and difficulty concentrating. the brain is one of the first organs affected by reduced oxygen supply. cognitive clarity, memory, and processing speed all suffer. for more on addressing brain fog, read Understanding Brain Fog: Causes and Solutions for Women.
what to do
eat iron-rich foods consistently. lean red meat, poultry, and fish are the most bioavailable sources. plant sources include lentils, beans, tofu, pumpkin seeds, dark leafy greens, and fortified cereals. pair all plant-based iron sources with vitamin C to significantly increase absorption.
avoid iron inhibitors around meals. calcium, coffee, tea, and certain medications block iron absorption. space them at least an hour away from iron-rich meals or supplements.
consider supplementation. if your diet is not meeting your needs or your levels are significantly low, your healthcare provider may recommend iron supplements. ferrous bisglycinate is generally the most well-tolerated form.
get tested. a simple blood test measuring serum ferritin (stored iron) alongside haemoglobin gives the full picture. serum ferritin below 30 ng/mL is associated with symptoms even when haemoglobin is technically normal. know your numbers.
your energy, your clarity, your vitality — these are not fixed. they are nutritional. the body is responsive when you give it what it needs.
