What to watch with Eisen-Ferritin Selbsttest and weight loss?

An iron-ferritin self-test measures your ferritin level, reflecting iron stores. During weight loss, it can offer insights, but caution: ferritin is an acute-phase reactant – inflammation, infection, or exercise can skew results. Caloric restriction often lowers ferritin slowly; a low value may indicate iron deficiency, worsening fatigue and performance. A high ferritin (>200 ng/ml) may suggest hemochromatosis or inflammation – both need medical follow-up. The self-test alone cannot replace clinical workup (CBC, transferrin saturation, CRP). Evidence: human-moderate for ferritin as biomarker, but self-testing without context is limited. Safety note: Do not interpret without a doctor if you have liver disease or known iron overload. Weight loss alters iron needs – ensure adequate intake (e.g., meat, legumes, vitamin C).
