Which symptom is a typical sign of anemia?

Fatigue is a typical sign of anemia due to the decreased oxygen-carrying capacity of the blood. Anemia results from a lack of healthy red blood cells or hemoglobin, leading to inadequate oxygen delivery to tissues and organs. When the body is not receiving enough oxygen, one of the most common symptoms experienced is extreme tiredness or fatigue. This occurs because the muscles and organs are not getting the energy they need to function optimally. A person with anemia often feels weak and tired even after adequate rest, highlighting the body's struggle to maintain energy levels amidst low oxygen availability. This makes fatigue a classic symptom of anemia, directly related to its physiological effects.
