Chronic inflammation prevents normal iron utilization and red blood cell production.
Anemia of inflammation (also called anemia of chronic disease) occurs when chronic inflammatory conditions reduce iron availability and erythropoietin response, despite adequate iron stores.
Inflammatory anemia develops when chronic diseases such as rheumatoid arthritis, infections, or cancers trigger sustained inflammation that upregulates hepcidin, a hormone regulating iron absorption and recycling. Elevated hepcidin locks iron in storage cells, making it unavailable for hemoglobin synthesis despite adequate total body iron. Additionally, inflammatory cytokines suppress erythropoietin production and red blood cell maturation. This type of anemia typically presents with low hemoglobin, low reticulocyte count, and normal or elevated iron stores, distinguishing it from iron deficiency anemia.
Inflammatory conditions impair iron utilization and erythropoietin response, resulting in anemia despite normal iron stores.
Treat the underlying inflammatory condition to improve anemia; managing inflammation is more effective than iron supplementation. Ensure adequate protein, B vitamins, and vitamin C intake to support red blood cell production. Work with healthcare providers to optimize management of chronic diseases and consider erythropoietin-stimulating agents if appropriate.
Inflammatory anemia improves primarily by treating the underlying inflammatory condition rather than iron supplementation.
