Possible causes of anemia include: 1  Certain medications. 2  Destruction of red blood cells earlier than normal (which may be caused by immune system problems) 3  Long-term (chronic) diseases such as chronic kidney disease, cancer, ulcerative colitis, or rheumatoid arthritis.
Blood Loss. Blood loss is the most common cause of anemia, especially iron-deficiency anemia. Blood loss can be short term or persist over time. Heavy menstrual periods or bleeding in the digestive or urinary tract can cause blood loss. Surgery, trauma, or cancer also can cause blood loss. If a lot of blood is lost, the body may lose enough red blood cells to cause anemia.
