There are more than 400 types of anemia. These types of anemia are divided into three main groups, according to their cause.
There is anemia caused by blood loss, by decreased or faulty red blood cell production, and by destruction of red blood cells.
Anemia caused by blood loss is the result of chronic bleeding. Common causes of chronic bleeding related to anemia include gastrointestinal conditions such as ulcers, use of nonsteriodal anti- inflammatory drugs including aspirin and Motrin, and menstruation and childbirth.
Sickle cell anemia, iron deficiency anemia, vitamin deficiency, and bone marrow and stem cell problems are associated with anemia as the result of decreased or faulty red blood cell production. Because there are either too few blood cells or blood cells are not functioning correctly, anemia can result. A lack of vitamins or minerals can cause blood cells to be faulty.
Hemolytic anemia is anemia caused by the destruction of red blood cells. Bloods cells are destroyed because they are too fragile to withstand the routine stress of the circulatory system. This condition may be present at birth or develop over time. Sometimes there is no known cause for the development of hemolytic anemia.
