Could Your Anemia Be More Than Just Low Iron?
Published: Jan 10, 2024
Anemia isn't just about low iron; it can be a sign of complex blood disorders. Understanding the different types of anemia can lead to effective treatments and improved health outcomes.
Types of Anemia
Anemia can be caused by various factors, not just iron deficiency. Hemolytic anemia involves the destruction of red blood cells, often detected by bite cells in a blood smear. In contrast, macrocytic anemia, such as that caused by vitamin B12 deficiency, results in larger than normal red cells.
Diagnostic Power of Blood Smears
Blood smears are crucial in diagnosing the type of anemia. They reveal the shape and size of red blood cells, which can indicate the specific anemia type. For instance, the presence of schistocytes suggests a serious condition like thrombotic thrombocytopenic purpura.
Beyond Iron: Other Causes
Anemia can also result from chronic disease, lead exposure, or hereditary conditions. Each has distinct blood cell characteristics visible under a microscope, aiding in pinpointing the exact cause and guiding treatment.
