Allergic reactions are more common with iron dextran and may necessitate switching to a different preparation.

Severe side effects other than allergic reactions are rare and include urticaria hivespruritus itchingand muscle and joint pain. Red blood cell transfusions may be given to patients with severe iron-deficiency anemia who are actively bleeding or have significant symptoms such as chest pain, shortness of breath, or weakness.

The following groups of people are at highest risk for iron-deficiency anemia: Women who menstruate, particularly if menstrual periods are heavy Women who are pregnant or breastfeeding or those who have recently given birth People who have undergone major surgery or physical trauma People with gastrointestinal diseases such as celiac disease sprueinflammatory bowel diseases such as ulcerative colitis, or Crohn disease People with peptic ulcer disease People who have undergone bariatric procedures, especially gastric bypass operations Vegetarians, vegans, and other people whose diets do not include iron-rich foods Iron from vegetables, even those that are iron-rich, is not absorbed as well as iron from meat, poultry, and fish.

Children who drink more than 16 to 24 ounces a day of cow's milk Cow's milk not only contains little iron, but it can also decrease absorption of iron and irritate the intestinal lining causing chronic blood loss.

Other less common causes of iron deficiency include: Blood loss from the gastrointestinal tract due to gastritis inflammation of the stomachesophagitis inflammation of the esophagusulcers in the stomach or bowel, hemorrhoids, angiodysplasia leaky blood vessels similar to varicose veins in the gastrointestinal tractinfections such as diverticulitis, or tumors in the esophagus, stomach, small bowel, or colon Blood loss from chronic nosebleeds Blood loss from the kidneys or bladder Frequent blood donations Intravascular hemolysis, a condition in which red blood cells break down in the blood stream, releasing iron that is then lost in the urine.

This sometimes occurs in people who engage in vigorous exercise, particularly jogging. This can cause trauma to small blood vessels in the feet, so called "march hematuria.

What Other Tests Will Be Done If Iron Deficiency Is Diagnosed? These tests may include the following: Testing for blood in the stool fecal occult blood test Looking for abnormalities in the gastrointestinal tract - upper and lower endoscopy looking into the stomach, esophagus, or colon with a tubecapsule enteroscopy swallowing a tiny camera that takes images of the gastrointestinal tractbarium enema, barium swallow, or small bowel biopsy Testing the urine for blood or hemoglobin In women with abnormal or increased menstrual blood losses, a gynecologic evaluation that may include a pelvic ultrasound or uterine biopsy Sometimes it is difficult to diagnose the cause of iron deficiency, or your doctor may be concerned that there is a problem other than iron deficiency causing the anemia.

How Is Iron Deficiency Treated? There are several ways to increase iron intake: Diet Meat: beef, pork, or lamb, especially organ meats such as liver Poultry: chicken, turkey, and duck, especially liver and dark meat Fish, especially shellfish, sardines, and anchovies Leafy green members of the cabbage family including broccoli, kale, turnip greens, and collard greens Legumes, including lima beans, peas, pinto beans, and black-eyed peas Iron-enriched pastas, grains, rice, and cereals Medicinal Iron The amount of iron needed to treat patients with iron deficiency is higher than the amount found in most daily multivitamin supplements.

White blood cells fight infection, platelets help blood clot and red blood cells carry oxygen throughout the body. Red blood cells have an iron-rich protein that gives blood its red color, called hemoglobin. Hemoglobin lets red blood cells carry oxygen from the lungs to all parts of the body. And it lets red blood cells carry carbon dioxide from other parts of the body to the lungs to be breathed out. Spongy matter inside many of the large bones, called bone marrow, makes red blood cells and hemoglobin. To make them, the body needs iron, vitamin B, folate and other nutrients from foods. Iron deficiency anemia. Too little iron in the body causes this most common type of anemia. Bone marrow needs iron to make hemoglobin. Without enough iron, the body can't make enough hemoglobin for red blood cells. Pregnant people can get this type of anemia if they don't take iron supplements. Blood loss also can cause it. Blood loss might be from heavy menstrual bleeding, an ulcer, cancer or regular use of some pain relievers, especially aspirin. Vitamin deficiency anemia. Besides iron, the body needs folate and vitamin B to make enough healthy red blood cells. A diet that doesn't have enough of these and other key nutrients can result in the body not making enough red blood cells. Also, some people can't absorb vitamin B This can lead to vitamin deficiency anemia, also called pernicious anemia. Ongoing, called chronic, conditions. Having cancer, kidney failure, diabetes or another chronic condition increases the risk of anemia of chronic disease. These conditions can lead to having too few red blood cells. Slow, chronic blood loss from an ulcer or other source within the body can use up the body's store of iron, leading to iron deficiency anemia. Many types of anemia can't be prevented. But eating a healthy diet might prevent iron deficiency anemia and vitamin deficiency anemias. A healthy diet includes:.

This video—presented by the National Heart, Lung, and Blood Institute, part of the National Institutes of Health—shows how Susan, a full-time worker and student, has coped with having iron-deficiency anemia. Prior to her diagnosis, Susan had symptoms such as tiredness, poor skin tone, dizziness, and depression. After her doctor diagnosed her with iron-deficiency anemia, Susan got counseling on how to improve her health and well-being. She began taking iron supplements and multivitamins to improve her iron levels. Susan also made changes to her diet, such as focusing more on green leafy vegetables, red meats, nuts, dried fruits, and beans. Other lifestyle changes, such as getting enough sleep and exercising, also have helped Susan feel better. To further improve her condition, Susan had a minor surgical procedure to stop her monthly periods. By following her treatment plan and making smart lifestyle choices, Susan continues to feel better and see the benefits of treatment.
