What Are the Different Types of Anemia?
There are three broad categories of causes of anemia. First, when someone is injured and loses a great deal of blood, anemia can develop because the body’s total blood volume is lost faster than it can be replaced. In the second category, the process of making red blood cells in the body is not working normally: bone marrow does not make enough erythrocytes, the erythrocytes do not contain enough hemoglobin, or the hemoglobin does not function correctly. In the third category, red blood cells are destroyed faster than the marrow can replenish them. Some of the most common types of anemia in each category are described below.
