What are the signs of low iron in women?
Bottom lineThe common signs of low iron in women are fatigue that sleep does not fix, breathlessness, pale skin, brittle nails, hair shedding, cold hands and feet, headaches, dizziness, restless legs, and ice cravings. Women are at higher risk because periods lose iron each cycle. Iron stores (ferritin) fall before a standard blood count does, so ask for a ferritin test if you feel deficient but were told your count is normal; a blood test, not symptoms, confirms it.
Low iron is easy to miss because the symptoms come on slowly and get blamed on a busy life. The most common signs in women are fatigue that sleep does not fix, breathlessness, pale skin, brittle nails, and hair shedding.
The common signs
- Persistent tiredness and low energy, even after rest
- Breathlessness on stairs or light activity
- Pale skin, or paleness inside the lower eyelids
- Brittle nails and increased hair loss
- Cold hands and feet
- Headaches, dizziness, or a fast or pounding heartbeat
- Restless legs at night
- Pica - craving and chewing ice or non-food items like clay or paper
Why women are at higher risk
Menstruation loses iron every cycle, and heavy or long periods lose more. Pregnancy and a plant-heavy diet add to the demand. Roughly a third of women of reproductive age have low iron stores.
Low iron vs anemia
Your body drains iron in stages. Ferritin (your iron store) falls first, so you can feel deficient while a basic blood count still reads normal. If you have these signs but were told your count is fine, ask specifically about a ferritin test - it catches the problem earlier.
When to see a doctor
See a clinician if several of these signs stack up, especially alongside heavy periods. Iron deficiency is diagnosed with a blood test, never guessed from symptoms alone, and it is very treatable once found.
