Anemia is not just a single illness but it is a condition that has variety of causes and forms. This is a result of the deficiency in the number of functioning red blood cells. It is the red blood cell which carries blood around the body with the help of a certain protein called hemoglobin. Anemia could mean that either the level of hemoglobin or red blood cell is low.
When a person has anemia, the workload of the heart is increased because it has to work harder in order to produce the amount of blood needed to get the required amount of oxygen around the body. This is why when an anemic person exercises, he gets exhausted right away.
