Iron deficiency anemia -

Without iron supplementation, iron deficiency anemia occurs in many pregnant women because their iron stores need to serve their own increased blood volume as well as be a source of hemoglobin for the growing fetus.

These groups of people may have an increased risk of iron deficiency anemia: Women. Because women lose blood during menstruation, women in general are at greater risk of iron deficiency anemia. Infants and children. Infants, especially those who were low birth weight or born prematurely, who don't get enough iron from breast milk or formula may be at risk of iron deficiency.

Children need extra iron during growth spurts. If your child isn't eating a healthy, varied diet, he or she may be at risk of anemia. People who don't eat meat may have a greater risk of iron deficiency anemia if they don't eat other iron-rich foods.

Frequent blood donors. People who routinely donate blood may have an increased risk of iron deficiency anemia since blood donation can deplete iron stores.

Low hemoglobin related to blood donation may be a temporary problem remedied by eating more iron-rich foods. If you're told that you can't donate blood because of low hemoglobin, ask your doctor whether you should be concerned.

However, left untreated, iron deficiency anemia can become severe and lead to health problems, including the following: Heart problems. Iron deficiency anemia may lead to a rapid or irregular heartbeat. Your heart must pump more blood to compensate for the lack of oxygen carried in your blood when you're anemic.

This can lead to an enlarged heart or heart failure. Problems during pregnancy. In pregnant women, severe iron deficiency anemia has been linked to premature births and low birth weight babies. But the condition is preventable in pregnant women who receive iron supplements as part of their prenatal care.

Growth problems. In infants and children, severe iron deficiency can lead to anemia as well as delayed growth and development. Additionally, iron deficiency anemia is associated with an increased susceptibility to infections.

You can reduce your risk of iron deficiency anemia by choosing iron-rich foods. Choose iron-rich foods Foods rich in iron include: Red meat, pork and poultry Seafood Beans Dark green leafy vegetables, such as spinach Dried fruit, such as raisins and apricots Iron-fortified cereals, breads and pastas Peas Your body absorbs more iron from meat than it does from other sources.

Choose foods containing vitamin C to enhance iron absorption You can enhance your body's absorption of iron by drinking citrus juice or eating other foods rich in vitamin C at the same time that you eat high-iron foods.

Vitamin C is also found in: Broccoli Grapefruit Kiwi Leafy greens Melons Oranges Peppers Strawberries Tangerines Tomatoes. Preventing iron deficiency anemia in infants To prevent iron deficiency anemia in infants, feed your baby breast milk or iron-fortified formula for the first year.

Symptoms of iron deficiency anemia tend to develop gradually and are similar to symptoms produced by other types of anemia, such as fatigue, weakness, and paleness.

Many people with severe iron deficiency anemia have pica Pica Pica is an eating disorder characterized by regularly eating things that are not food. Usually, what people with pica eat does not harm them, but sometimes what they eat causes complications People with pica have a craving to ingest something, most commonly ice but sometimes a substance that is not food, such as dirt, clay, or chalk.

Once blood tests show a person has anemia, tests for iron deficiency are often done. With iron deficiency, the red blood cells tend to be small and pale. Blood levels of iron and transferrin the protein that carries iron when it is not inside red blood cells are measured and compared.

The most accurate test for iron deficiency is a measurement of the blood level of ferritin a protein that stores iron. A low level of ferritin indicates iron deficiency. However, sometimes ferritin levels are misleading because they can be falsely elevated and thus appear normal due to liver damage, inflammation, infection, or cancer.

Because excessive bleeding is the most common cause of iron deficiency, the first step is to locate its source and stop the bleeding. Normal dietary iron intake usually cannot compensate for iron loss due to chronic bleeding, and the body has a very small iron reserve.

Consequently, lost iron must be replaced by taking iron supplements. Correcting iron deficiency anemia with iron supplements usually takes 3 to 6 weeks, even after the bleeding has stopped. Iron supplements are usually taken by mouth.

Iron supplements make the stool look dark or black and often cause constipation. An iron supplement is absorbed best when taken 30 minutes before breakfast with a source of vitamin C either orange juice or a vitamin C supplement.

Sometimes, iron is given by vein intravenously when large amounts of iron are needed or when the person cannot tolerate taking iron by mouth.
