Anemia is a medical condition in which the red blood cell count or hemoglobin is less than normal. The normal level of hemoglobin is generally different in males and females. For men, anemia is typically defined as hemoglobin level of less than 13.5 gram/100 ml and in women as hemoglobin of less than 12.0 gram/100 ml. These definitions may vary slightly depending on the source and the laboratory reference used.
Some patients with anemia have no symptoms. Others with anemia may feel:
Develop palpitations (feeling of heart racing)
Become short of breath
