Topic overview

Start with the big picture

The lesson organizes anemia assessment around hemoglobin and mean corpuscular volume (MCV), distinguishing microcytic, normocytic, and macrocytic patterns. It connects common symptoms and signs to reduced oxygen delivery and surveys causes such as iron deficiency, chronic kidney disease, inflammation, vitamin deficiencies, hemolysis, and blood loss. The diagnostic work-up includes blood counts and indices, reticulocyte count, iron and vitamin studies, kidney function, and assessment for occult blood loss. Treatment sections address oral and intravenous iron, vitamin B₁₂ and folate replacement, and erythropoiesis-stimulating agents. Patient counseling, therapeutic goals, transfusion, and drug-induced anemia are also included in the lesson structure.
