Anemia ia a disease that affects the number of red blood cells or hemoglobin content in the blood. Anemia is the most common disorder of the blood. The three main causes of anemia are: 1) excessiv blood loss, either acute through hemorrhaging, or chronic through controlled blood loss; 2) excessive blood cell destruction (hemolysis); and 3) deficient red blood cell production (hematopoiesis).
Symptoms of patients with anemia are weakness, fatigue, general malaise, sometimes poor concentration, and signs of heart failure. Anemia is most often identified by a laboratory analysis of the blood by getting a red blood cell count and a hemoglobin count.
