Causes, incidence, and risk factors
Hemoglobin, which gives blood cells their red color, is the protein that carries the oxygen within a red blood cell. Patients with anemia have deficiencies in hemoglobin. Depending on the type of anemia you have, the cause may vary. Some possible causes for anemia include:
- Certain medications
- Diseases such as cancer or rheumatoid arthritis
- Genes -- some forms of anemia can be inherited
- Kidney failure
- Blood loss (for example, from heavy menstrual periods)
- Poor diet
- Pregnancy
- Problems with bone marrow (where blood cells are made)
- Problems with the immune system that cause the destruction of blood cells
- Surgery to the stomach or intestines that reduces the absorption of iron, vitamin B12, or folic acid
