What are the causes of anemia?
Iron deficiency anemia. This most common type of anemia is caused by a lack of iron in the body.
Without iron supplements, this type of anemia occurs in many pregnant women. It is also caused by blood loss, such as heavy menstrual bleeding. Ulcers in the stomach or small intestine. Large intestine cancer. Regular use of some over-the-counter pain relievers, especially aspirin, can cause inflammation of the stomach lining, leading to blood loss.
Vitamin deficiency anemia. Besides iron, your body needs folic acid and vitamin B12 to produce enough healthy red blood cells. A diet lacking in these other key nutrients can cause decreased red blood cell production.
Inflammatory anemia. Diseases such as cancer, HIV/AIDS, rheumatoid arthritis, kidney disease, Crohn’s disease and other acute or chronic inflammatory diseases can interfere with red blood cell production..
Anemia associated with bone marrow disease. A variety of diseases, such as leukemia and myelofibrosis, can cause anemia by affecting blood production in the bone marrow. The effects of these types of cancer and cancer-like disorders vary from mild to life-threatening.
Hemolytic anemia. This group of anemia develops when red blood cells are destroyed faster than the bone marrow can replace them. Some blood diseases increase the destruction of red blood cells. You can inherit hemolytic anemia, or you can develop it later in life.
Sickle cell anemia. This genetic and sometimes serious condition is hemolytic anemia. It is caused by a defective form of hemoglobin that forces the red blood cells to take on an abnormal crescent (sickle) shape. These irregular blood cells die prematurely, resulting in a chronic deficiency of red blood cells..
