Young woman with pale skin and tired eyes wrapped in a beige blanket, holding her chest as if feeling weak or dizzy, illustrating common iron deficiency symptoms like fatigue and shortness of breath.
The tiredness rest doesn't fix, plus pale skin, lips, and inner eyelids, are the most common signs of iron deficiency - and the easiest to brush off as just being busy or stressed.
With too little hemoglobin your blood carries less oxygen, so you get winded easily and your heart beats faster or pounds to keep up - sometimes with headaches or dizziness too.
Poor oxygen circulation leaves hands and feet cold, and nails turn thin, brittle, or spoon-shaped. Hair can thin too - small signs that add up.
Iron deficiency affects up to 30% of people, and its hidden costs - weakened immunity, pregnancy and child-development risks - build silently. A simple blood panel confirms it.
