Low ferritin levels stem from insufficient iron intake, chronic blood loss, or increased iron demand during pregnancy. Ferritin, a protein storing iron in your body, drops when iron reserves deplete.
Ferritin acts as your body's iron bank, releasing stored iron when needed. Your liver, spleen, and bone marrow produce it. When ferritin levels fall below 30 ng/mL, iron deficiency may develop, potentially causing anemia (National Library of Medicine).
Low ferritin results from inadequate iron supply, excessive iron loss, or heightened iron demand. Common causes include:
Early symptoms include fatigue, weakness, and pale skin. Untreated low ferritin leads to iron deficiency anemia, causing dizziness, shortness of breath, and brittle nails. Severe cases may require intravenous iron therapy.
Doctors diagnose low ferritin through blood tests measuring serum ferritin levels. Treatment includes iron supplements, dietary changes, and addressing underlying conditions. Foods rich in heme iron, like red meat and shellfish, improve absorption.
I once helped a friend with low ferritin by adjusting her diet to include more leafy greens and lean meats. Within weeks, her energy levels improved.
Prevent low ferritin by consuming iron-rich foods, taking supplements if needed, and managing chronic conditions. Pair iron-rich meals with vitamin C to improve absorption. Avoid coffee and tea near mealtimes, as they inhibit iron uptake.
Many believe low ferritin only affects vegans or vegetarians. However, even omnivores can develop deficiencies due to poor absorption or hidden blood loss. Another myth is that iron supplements always cause constipation; slow-release formulas minimize this risk.
