What to watch with Ferritin Eisenmangel and menopause?

The question about ferritin and iron deficiency in menopause is clinically important, but the provided context contains no specific information on ferritin, iron metabolism, or menopause. Therefore, the answer must rely on general medical knowledge. Ferritin reflects iron stores; low levels indicate iron deficiency. During menopause, iron requirements decrease due to cessation of menstruation, yet deficiency can still occur – e.g., from chronic blood loss (fibroids, polyps, GI bleeding), inadequate intake, or malabsorption (celiac disease, Helicobacter). Symptoms include fatigue, poor concentration, hair loss, restless legs syndrome. A ferritin below 30 µg/L indicates overt deficiency; values between 30 and 100 µg/L may already cause functional impairment. Importantly, ferritin is an acute-phase reactant – inflammation can falsely elevate it despite deficiency. Thus, CRP should always be measured. Genetic testing for iron deficiency is not useful; no validated polygenic scores for ferritin levels exist. Evidence for supplementation (iron, vitamin C) is moderate, but self-treatment without medical evaluation is risky (iron overload, liver damage). In menopause, also monitor thyroid function and vitamin B12 status. Evidence: human-moderate (for general iron deficiency diagnostics), but due to lack of context-specific data rated as 'unclear'.
