However, these indicators are not sensitive or specific enough to adequately describe the full spectrum of iron status, and this can complicate the diagnosis of iron deficiency. The RDA for women 51+ years drops to 8 mg with the assumption that cessation of menstruation has occurred with menopause. Potential causes of iron deficiency in people with heart failure include poor nutrition, malabsorption, defective mobilization of iron stores, cardiac cachexia, and use of aspirin and oral anticoagulants, which might result in the loss of some blood in the gastrointestinal tract [61].

[, Siu AL, on behalf of the US Preventive Services Task Force. Guidelines vary on dietary iron intakes and possible supplementation to ensure adequate iron status and to prevent or treat IDA in infants and young children: Some studies have suggested that iron supplementation in young children living in areas where malaria is endemic could increase their risk of malaria [75,76]. Between 1983 and 2000, at least 43 U.S. children died from ingesting supplements containing high doses of iron (36443 mg iron/kg body weight) [27]. Blood levels should be rechecked periodically, and supplements discontinued or taken at a lower dosage if levels return to normal, as long-term high dosages can lead to constipation or other digestive upset. Web10. Because proton pump inhibitors, such as lansoprazole (Prevacid) and omeprazole (Prilosec), reduce the acidity of stomach contents, they can reduce iron absorption [3]. However, the effects of enhancers and inhibitors of iron absorption are attenuated by a typical mixed western diet, so they have little effect on most peoples iron status. The condition can be difficult to diagnose because, although low serum ferritin levels indicate iron deficiency, these levels tend to be higher in patients with infection or inflammation [80]. Iron.

Iron is a mineral that has many functions. The main causes of iron deficiency in people with cancer are anemia of chronic disease (discussed in the Iron and Health section below) and chemotherapy-induced anemia. Adolescents 14-18 years actively growing also need higher iron: 11 mg for boys, 15 mg for girls, 27 mg for pregnancy, and 10 mg for lactation. Serum ferritin concentration, a measure of the body's iron stores, is currently the most efficient and cost-effective test for diagnosing iron deficiency [11-13]. Acute intakes of more than 20 mg/kg iron (about 1,365 mg iron for a person weighing 150 lb) from supplements or medicines can lead to corrosive necrosis of the intestine, which might lead to fluid and blood loss, shock, tissue damage, and organ failure, especially if food is not taken at the same time as the iron [89]. The WHO therefore recommends 6-month supplementation cycles as follows: children aged 24 to 59 months should receive 25 mg iron and those aged 5 to 12 years should receive 45 mg every week for 3 months, followed by 3 months of no supplementation [75].

Certain factors can improve or inhibit the absorption of non-heme iron. Disorders of iron metabolism: New diagnostic and treatment approaches to iron deficiency. The combination of low iron intake and high iron loss can lead to a negative iron balance; reduced production of hemoglobin; or microcytic, hypochromic anemia [58]. Frequently used forms of iron in supplements include ferrous and ferric iron salts, such as ferrous sulfate, ferrous gluconate, ferric citrate, and ferric sulfate [3,27]. Some people have a hereditary condition called hemochromatosis that causes an excessive buildup of iron in the body. A complementary approach is to consider how iron intakes from the diet and dietary supplements compare with recommended intakes. Am J Clin Nutr 2001;73:638-46. Typically, a doctor screens for anemia by first checking a complete blood count (including hemoglobin, hematocrit, and other factors that measure red blood cell volume and size).

The FNB has established ULs for iron from food and supplements based on the amounts of iron that are associated with gastrointestinal effects following supplemental intakes of iron salts (see Table 3).
