How are Ferritin Eisenmangel and Wechseljahre related?

Ferritin is the body's main iron storage protein. Iron deficiency (low ferritin) is common during perimenopause due to heavier and more irregular menstrual bleeding, which increases iron loss. After menopause, blood loss stops, so ferritin levels often rise – sometimes excessively, which may contribute to oxidative stress. However, ferritin is also an acute-phase reactant, meaning inflammation can falsely elevate it. The menopause transition itself does not directly cause iron deficiency, but the interplay of bleeding patterns, hormonal changes, and potential gut absorption issues matters. Testing ferritin is useful but should be interpreted alongside CRP and transferrin saturation. The evidence is based on established physiology and clinical observation, not on the provided context.
