Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen ...
Iron-deficiency anemia is anemia caused by a lack of iron. [3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. [3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [1]
Nutritional iron deficiency is common in developing nations. An estimated two-thirds of children and of women of childbearing age in most developing nations are estimated to have iron deficiency without anemia with one-third of them having an iron deficiency with anemia. [96] Iron deficiency due to inadequate dietary iron intake is rare in men ...
The researchers discovered that, between 2003 and 2020, almost 40% of women and girls were deficient in iron and 6% actually had iron-deficiency anemia — a condition where the blood doesn't have ...
In 2020, 900 million women and children had anemia, which is often caused by iron deficiency. [37] More than 3.1 billion people in the world – 42% – were unable to afford a healthy diet in 2021. More than 3.1 billion people in the world – 42% – were unable to afford a healthy diet in 2021.
Anemia is a deficiency in the size or number of red blood cells or in the amount of hemoglobin they contain. [1] This deficiency limits the exchange of O 2 and CO 2 between the blood and the tissue cells. [1] Globally, young children, women, and older adults are at the highest risk of developing anemia. [1]
Iron-deficiency anemia: D50: 6947: Iron-deficiency anemia (or iron deficiency anaemia) is a common anemia that occurs when iron loss (often from intestinal bleeding or menses) occurs, and/or the dietary intake or absorption of iron is insufficient. In such a state, hemoglobin, which contains iron, cannot be formed. [5]
Latent iron deficiency (LID), also called iron-deficient erythropoiesis, [1] is a medical condition in which there is evidence of iron deficiency without anemia (normal hemoglobin level). [2] It is important to assess this condition because individuals with latent iron deficiency may develop iron-deficiency anemia.
