What to watch with Ferritin Eisenmangel and weight loss?

When dealing with low ferritin (iron deficiency) and weight loss, several points are important. Ferritin reflects iron stores; low levels indicate iron deficiency. Weight loss can be either a cause or a consequence: unintentional weight loss (e.g., from malabsorption, chronic inflammation, or malignancy) may present with iron deficiency as a secondary finding. Intentional weight loss (dieting) can worsen iron status if dietary intake is insufficient. Watch for symptoms like fatigue, pallor, brittle nails, hair loss, or pica (cravings for non-food items). Ferritin is an acute-phase reactant; inflammation can falsely normalize or elevate it – measure CRP concurrently. Iron deficiency without anemia can still impair physical performance. Caution: only supplement iron after confirmed deficiency, as excess iron is toxic (risk of hemochromatosis). Unexplained weight loss requires medical workup (e.g., celiac, thyroid, malignancy).
