• A diet lacking in certain vitamins and minerals: A diet consistently low in iron, vitamin B-12, folate and copper increases your risk of anemia.
• Intestinal disorders: Having an intestinal disorder that affects the absorption of nutrients in your small intestine — such as Crohn's disease and celiac disease — puts you at risk of anemia.
• Menstruation: In general, women who haven't had menopause have a greater risk of iron deficiency anemia than do men and postmenopausal women. Menstruation causes the loss of red blood cells.
• Pregnancy: Being pregnant and not taking a multivitamin with folic acid and iron, increases your risk of anemia.
• Chronic conditions: If you have cancer, kidney failure or another chronic condition, you could be at risk of anemia of chronic disease. These conditions can lead to a shortage of red blood cells.
• Family history: If your family has a history of an inherited anemia, such as sickle cell anemia, you also might be at increased risk of the condition.
• Other factors: A history of certain infections, blood diseases and autoimmune disorders increases your risk of anemia. Alcoholism, exposure to toxic chemicals and the use of some medications can affect red blood cell production and lead to anemia.
• Age: People over age 65 are at increased risk of anemia.
