![]() If your anemia is due to a chronic disease, treatment of the underlying disease will often improve the anemia. Treatment varies from changing your diet to taking dietary supplements. Other nutritional anemias, such as folate or B-12 deficiency, may result from poor diet or from an inability to absorb vitamins in the gastrointestinal tract. If you have iron-deficiency anemia, your doctor may order tests to determine if you are losing blood from your stomach or bowels. Iron-deficiency anemia is almost always due to blood loss. The treatment for anemia depends on what causes it. Chemotherapy used to treat various cancers often impairs the body's ability to make new red blood cells, and anemia often results from this treatment. For example, some patients with kidney disease develop anemia because the kidneys are not making enough of the hormone erythropoietin to signal the bone marrow to make new or more red blood cells. Sickle cell anemia is an inherited hemolytic anemia in which the hemoglobin protein is abnormal, causing the red blood cells to be rigid and clog the circulation because they are unable to flow through small blood vessels.Īnemia caused by other diseases - Some diseases can affect the body's ability to make red blood cells. Examples of inherited hemolytic anemias include some types of thalassemia and low levels of enzymes such as glucose-6 phosphate dehydrogenase deficiency. Inherited abnormalities may affect the hemoglobin or the red blood cell structure or function. Hemolytic anemia may be due to mechanical causes (leaky heart valves or aneurysms), infections, autoimmune disorders, or congenital abnormalities in the red blood cell. Hemolytic anemia occurs when red blood cells are broken up in the bloodstream or in the spleen. ![]() Viral infections, ionizing radiation, and exposure to toxic chemicals or drugs can also result in aplastic anemia. However, the few blood cells the marrow does make are normal. This occurs as a result of destruction or deficiency of blood-forming stem cells in your bone marrow, in particular when the body’s own immune system attacks the stem cells. Pernicious anemia is a condition in which vitamin B12 cannot be absorbed in the gastrointestinal tract.Īnemia and Pregnanc y - Learn about the risk factors and symptoms of anemia during pregnancy.Īplastic anemia is a rare bone marrow failure disorder in which the bone marrow stops making enough blood cells (red blood cells, white blood cells, and platelets). Vitamin-deficiency anemia may result from low levels of vitamin B12 or folate (folic acid), usually due to poor dietary intake. People who have had gastric bypass surgery for weight loss or other reasons may also be iron deficient due to poor absorption. Pregnancy and childbirth consume a great deal of iron and thus can result in pregnancy-related anemia. Iron deficiency is usually due to blood loss but may occasionally be due to poor absorption of iron. It happens when you do not have enough iron in your body. Iron-deficiency anemia is the most common type of anemia. In fact, many people do not even realize that they have anemia until it is identified in a blood test. The signs and symptoms of anemia can easily be overlooked. Inflammatory bowel disease (Crohn disease or ulcerative colitis).Rheumatoid arthritis or other autoimmune disease.If you have any of the following chronic conditions, you might be at greater risk for developing anemia: The risk of anemia increases as people grow older. Women who are menstruating or pregnant and people with chronic medical conditions are most at risk for this disease. Many people are at risk for anemia because of poor diet, intestinal disorders, chronic diseases, infections, and other conditions. When you have anemia, your body lacks oxygen, so you may experience one or more of the following symptoms:
