![]() ![]() People over age 65 are at increased risk of anemia. ![]() Alcoholism, exposure to toxic chemicals and the use of some medications can affect red blood cell production and lead to anemia. A history of certain infections, blood diseases and autoimmune disorders increases your risk of anemia. 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. Slow, chronic blood loss from an ulcer or other source within your body can deplete your body's store of iron, leading to iron deficiency anemia. These conditions can lead to a shortage of red blood cells. If you have cancer, kidney failure or another chronic condition, you could be at risk of anemia of chronic disease. Being pregnant and not taking a multivitamin with folic acid and iron, increases your risk of anemia.Ĭhronic conditions. Menstruation causes the loss of red blood cells. In general, women who haven't had menopause have a greater risk of iron deficiency anemia than do men and postmenopausal women. 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. A diet consistently low in iron, vitamin B-12, folate and copper increases your risk of anemia. A diet lacking in certain vitamins and minerals.These factors place you at increased risk of anemia: These irregular blood cells die prematurely, resulting in a chronic shortage of red blood cells. It's caused by a defective form of hemoglobin that forces red blood cells to assume an abnormal crescent (sickle) shape. This inherited and sometimes serious condition is a hemolytic anemia. You can inherit a hemolytic anemia, or you can develop it later in life. Certain blood diseases increase red blood cell destruction. This group of anemias develops when red blood cells are destroyed faster than bone marrow can replace them. The effects of these types of cancer and cancer-like disorders vary from mild to life-threatening. A variety of diseases, such as leukemia and myelofibrosis, can cause anemia by affecting blood production in your bone marrow. Anemias associated with bone marrow disease.Causes of aplastic anemia include infections, certain medicines, autoimmune diseases and exposure to toxic chemicals. This rare, life-threatening anemia occurs when your body doesn't produce enough red blood cells. Certain diseases - such as cancer, HIV/ AIDS, rheumatoid arthritis, kidney disease, Crohn's disease and other acute or chronic inflammatory diseases - can interfere with the production of red blood cells. ![]() This can lead to vitamin deficiency anemia, also known as pernicious anemia. Some people who consume enough B-12 aren't able to absorb the vitamin. A diet lacking in these and other key nutrients can cause decreased red blood cell production. Besides iron, your body needs folate and vitamin B-12 to produce enough healthy red blood cells. It's important to determine the source of iron deficiency to prevent recurrence of the anemia. ![]() It's also caused by blood loss, such as from heavy menstrual bleeding an ulcer in the stomach or small bowel cancer of the large bowel and regular use of some pain relievers that are available without a prescription, especially aspirin, which can cause inflammation of the stomach lining resulting in blood loss. Without iron supplementation, this type of anemia occurs in many pregnant women. Without adequate iron, your body can't produce enough hemoglobin for red blood cells. Your bone marrow needs iron to make hemoglobin. This most common type of anemia is caused by a shortage of iron in your body. Causes of anemiaĭifferent types of anemia have different causes. To produce hemoglobin and red blood cells, your body needs iron, vitamin B-12, folate and other nutrients from the foods you eat. Most blood cells, including red blood cells, are produced regularly in your bone marrow - a spongy material found within the cavities of many of your large bones. Hemoglobin enables red blood cells to carry oxygen from your lungs to all parts of your body and to carry carbon dioxide from other parts of the body to your lungs to be exhaled. Red blood cells contain hemoglobin - an iron-rich protein that gives blood its red color. Your body makes three types of blood cells - white blood cells to fight infection, platelets to help your blood clot, and red blood cells to carry oxygen from your lungs to the rest of your body and carbon dioxide from the body back to the lungs. Bleeding causes you to lose red blood cells more quickly than they can be replaced.Your body doesn't make enough red blood cells.Anemia occurs when your blood doesn't have enough red blood cells. Anemia can be due to a condition present at birth (congenital) or to a condition you develop (acquired). ![]()
