Iron deficiency is not always caused by inadequate dietary intake, but may result from various medical conditions. Dialysis treatment in people with chronic renal failure can lead to loss of iron; gastrointestinal inflammation (eg, in Crohn s disease or coeliac disease) may impair iron absorption; and gastrointestinal blood loss (eg

Iron: Deficiency and toxicity - DR. RONALD HOFFMAN

Iron deficiency and anemia: Iron deficiency and anemia are not the same. People may be iron deficient without being anemic. The term iron deficiency refers to depleted body iron stores without regard to the degree of depletion or to the presence of anemia. The term anemia refers to the severe depletion of iron stores that results in a low

Causes of Iron Deficiency Anemia The most common cause of iron deficiency anemia (IDA) in pre-menopausal women is menstrual blood loss. In post-menopausal women, blood loss from the gastrointestinal tract is more common.

Iron deficiency rapidly affects the epithelial cells thereby leading to dryness and roughness of the skin, dry and damaged hair, koilonychias and alopecia. In mild-to-moderate iron deficiency loss of tongue papillaeis reported. Atrophic glossitis is also noted in severe cases. Iron deficiency may be associated with restless legs syndrome [23].

Nutrition education material to address iron deficiency

Apr 01, 2012 According to the WHO (2006), iron deficiency (ID) and iron deficiency anemia (IDA) remain the most common nutritional disorders, affecting about two million people. ID and IDA are highly prevalent in sub-Saharan Africa; while affecting both genders, IDA is much more common in women of childbearing age and children (World Health Organization, 2006).


Oct 04, 2004 reported to occur in iron-sufficient children when blood lead concentration exceeds 60 µg/dL. The anemia is a normocytic, normochromic, well-compensated hemolytic anemia. However, in children with iron deficiency, the decrease in hemoglobin may occur at lower blood lead levels

Iron Deficiency Anemia: A Common and Curable Disease

Iron homeostasis in humans. Each day, 20 mg of iron is recycled between circulating transferrin (Fe-Tf ) and erythrocytes. This recycling pathway is supported by (A) intestinal iron absorption, (B) erythropha-gocytosis, (C) hepatic iron stores, and (D) iron incorporation into hemoglobin. For more details, see Andrews 2008.

United States and the United Kingdom, 30% had iron deficiency and 10% had IDA. This prevalence is even greater in children who are overweight (20%)5 and of Mexican American descent (17%).13 In addition to the known long-term consequences of IDA, some children will experience acute life-threaten-ing clinical events, including tachycardia, tachypnea,

Iron deficiency manifests as anaemia in up to 2 billion people, impairs physical and mental development in children, and can exacerbate many other health problems.

Latent iron deficiency and iron deficiency anemia correspond to mean absorption rates of 10% and 13%, respectively, whereas healthy males absorb 5% and healthy females 5.6%.60 Iron that remains in the intestinal lumen may cause mucosal injury,61,62 and studies in animal models suggest an exacer-

Approaches for Reducing the Risk of Early-Life Iron

Residual brain iron deficiency is likely responsible for the persistent neurological deficits in children with a history of early-life iron deficiency [3

paint, paint chips, or dust. Young children also absorb lead more easily than adults. Up to 50% of the lead a child ingests can be absorbed, compared to only 10% in adults. Children also are not as efficient in eliminating the lead they have absorbed. When a child has an iron deficiency, lead is more easily absorbed from the gastrointestinal tract.
