Anemia (uh-NEE-me-eh) is a condition in which a person's blood has a lower than normal number of red blood cells (RBCs), or the RBCs don't have enough hemoglobin (HEE-muh-glow-bin). Hemoglobin—an iron-rich protein that gives the red color to blood—carries oxygen from the lungs to the rest of the body. In people with anemia, the blood does not carry enough oxygen to the rest of the body. As a result, people with anemia feel tired, along with other symptoms, because their bodies are not receiving enough oxygen. In severe or prolonged cases of anemia, the lack of oxygen in the blood can cause serious and sometimes fatal damage to the heart and other organs of the body.
RBCs also are called erythrocytes (eh-RITH-ro-sites). RBCs are disc-shaped and look like doughnuts without a hole in the center. They are produced continually in the spongy marrow inside the large bones of the body and normally last 120 days. RBCs' main role is to carry oxygen, but they also remove carbon dioxide (a waste product) from cells and carry it to the lungs to be exhaled. White blood cells and platelets are the two other kinds of blood cells. White blood cells help fight infections. Platelets help blood to clot. In some kinds of anemia, there are low amounts of all three types of blood cells.
Women and people with chronic diseases are at greater risk for anemia. Many types of anemia can be mild, short-lived, and easily treated. Some forms of anemia can be prevented with a healthy diet, and other forms can be treated with diet supplements.
Certain types of anemia may be severe, long-lasting, and life threatening if not diagnosed and treated. People who have symptoms of anemia should see their doctor to find out if they have the condition, its cause and severity, and how to treat it.
