Anemia specifically refers to a condition in which there is a deficiency in the number of red blood cells or the quantity of hemoglobin they contain. This reduction hinders the blood's ability to carry adequate oxygen to the body's tissues, resulting in symptoms like fatigue, weakness, and pallor. The primary characteristic of anemia is the low red blood cell count, which can arise from various causes such as iron deficiency, vitamin deficiencies, chronic diseases, or bone marrow problems.

While other conditions may involve alterations in blood cell counts, such as elevated white blood cell counts (often indicating infection or inflammation) or changes in platelet levels (which can be a sign of clotting issues), these do not define anemia. Moreover, high iron levels may indicate a different disorder, such as hemochromatosis, but do not relate to the characteristic of a low red blood cell count that defines anemia. Thus, understanding the role of red blood cells in oxygen transport underscores why low red blood cell count is synonymous with anemia.
