In anemia, a decrease in the number of red blood cells (RBCs) transporting oxygen and carbon dioxide impairs the body's ability for gas exchange. The decrease may result from blood loss, increased destruction of RBCs (hemolysis), or decreased production of RBCs. Anemia is classified as acute or chronic. Acute anemia denotes a precipitous drop in the RBC population resulting from hemolysis or acute hemorrhage.
A wide array of diseases, including inflammations, infections, and malignancies, may at some point be associated with anemia. Much like a fever, anemia is a sign that requires investigation to determine the underlying etiology. Often, practicing physicians overlook mild anemia. Do you know key aspects of various causes?
