Signs and Symptoms
Red blood cells carry oxygen from the lungs to other tissues. Therefore, anemia symptoms usually relate to the tissues not receiving enough oxygen.
Mild anemia may cause minimal to no symptoms. With progressively worsening anemia, or anemia with sudden onset, people often experience fatigue or shortness of breath. Anemia can also cause pale skin, and if severe enough, a rapid heart rate. Some types of anemia can make the skin and the white part of the eyes turn yellow.
