Anemia is a deficiency of healthy red blood cells. Red blood cells are the primary transporters of oxygen within the body. Anemia also causes iron deficiency; the primary reason fatigue is a common symptom.
Anemia affects about 4 million Americans. Women, and individuals with a chronic disease, are at an increased risk. Women in their childbearing years are particularly susceptible to a form of anemia called iron-deficiency anemia, because of the blood loss from menstruation and the increased blood supply demands of a pregnancy. Seniors also may have a greater risk of developing anemia because of medical conditions.
There are three types of anemia:
Anemia caused by blood loss.
Anemia caused by decreased or faulty red blood cell production.
Anemia caused by destruction of red blood cells.
The symptoms of anemia vary, according to the type. Anemia may be associated with other medical conditions such as an ulcer, hemorrhage or cancer.
The most common symptoms associated with anemia are:
Shortness of breath and headache, particularly with exercise
