Anemia is a common blood disorder defined by a deficiency of healthy red blood cells or hemoglobin, leading to reduced oxygen transport to body tissues. It is clinically identified by low hemoglobin (typically \(<13.5\) g/dL for men, \(<12.0\) g/dL for women) or hematocrit levels. Symptoms often include fatigue, weakness, and dizziness.
