Iron overdose during pregnancy could be harmful, according to an Iranian university study.
Iron is often given to combat anemia in pregnancy but many women take extra iron. Anemia is a condition where the blood is unable to carry enough oxygen due to low number of red blood cells or because each red blood cell is unable to carry normal amounts of oxygen. Common symptoms of anemia include feeling tired, fainting, or breathless.
AdvertisementThe condition is often associated with low birth weight and premature birth but this does not mean that women should be popping iron pills or any vitamin pills indiscriminately, the study, published in the British Journal of Obstetrics and Gynecology said.
The researchers at Tarbiat Modarres University checked the effect of iron supplements on women whose red blood cell level was normal. They gave 370 women a 150mg dose of ferrous sulphate, which is equal to approximately 30mg of iron, every day throughout their pregnancy. A similar number of women were given a placebo or dummy pill containing no iron.
The number of women with high blood pressure, a disorder that can also cause problems for the mother and child, was higher in the women given the iron pills than in the other group, according to online edition of BBC News.
Lead researcher Saedeh Ziaei said, 'Our trial suggests that administering iron may have some disadvantages in non-anemic women'.
In western countries, unless a pregnant woman is suffering from anemia, iron supplementation is not routinely given during pregnancy.
In India, however, due to a variety of reasons like malnutrition, vegetarian diet and deep-frying of vegetables, it is assumed that most women are iron-deficient. Hence, doctors recommend pregnant women to take iron supplements routinely.
