Anemia a risk for women?

Lack of iron can pose health complications

Pregnant women and premenopausal women who still get their periods are at the highest risk of iron deficiency and iron-deficiency anemia, both of which can cause such problems as fatigue and severe neurological damage. But how concerned should women in general be?

Pretty concerned — especially given the risks of full-blown anemia. Although most of those who die of the condition are women age 65 and older, iron-deficiency anemia in younger women can cause pregnancy complications and serious health problems including persistent fatigue and heart failure.

“Iron is generally fairly difficult to get rid of except by losing blood or by having babies,” says Nancy Berliner, chief of hematology at Brigham and Women’s Hospital and deputy editor of Blood, the medical journal of the American Society of Hematology.

Menstruation and pregnancy are the main causes of iron deficiency in women. The National Heart, Lung, and Blood Institute says one in five women of child-bearing age has irondeficiency anemia, and about half of all pregnant women develop the condition, at least temporarily.

“Babies are excellent at siphoning iron away from their moms,” Berliner says.

During pregnancy, women’s bodies create more blood for themselves and their babies, which can deplete their iron stores. But regular menstruation and heavy periods — especially the flows experienced by pre-menopausal women — also take their toll.

If it’s not corrected, iron deficiency can lead to irondeficiency anemia, in which red blood cells don’t make enough hemoglobin, the protein that carries oxygen through the body. In addition to fatigue and neurological issues, the blood disorder can cause dizziness, a rapid heartbeat, less strength and cardiac complications.

Iron supplements can correct deficiencies and iron-deficiency anemia, but proceed with caution, doctors say. “I don’t recommend people self-medicating with iron,” Berliner says. The recommended daily allowance of iron is 18 milligrams for women age 19 to 50, and more for pregnant or lactating women.

While too little iron is not good, too much can lead to overload and can increase a person’s risk for such problems as heart failure, liver disease, diabetes and neurodegenerative conditions. Berliner recommends that women ask their doctor for testing before pursuing supplementation.

Sometimes, eating more of such foods as lean meat, chicken, seafood, fortified cereal and bread, nuts and beans can correct a deficiency. Iron supplements can cause an upset stomach or constipation — physicians can administer intravenous iron as an alternative.
