← Human Body & HealthIf a patient presents with fatigue and microcytic anemia despite adequate dietary iron intake, which consequence follows regarding iron regulation?
A)Increased hepcidin production is likely
B)Enterocytes uptake more dietary iron
C)Iron recycling from macrophages decreases✓
D)Transferrin saturation levels will increase
💡 Explanation
Iron recycling decreases in conditions like anemia of chronic disease because inflammatory cytokines stimulate hepcidin production. Hepcidin then binds to ferroportin on macrophages, inhibiting iron release; therefore, less iron is available for erythropoiesis, rather than more being readily available.
