Iron deficiency can also cause shortness of breath, and amplify the symptoms of any chronic condition, such as depression. ... It has also been linked to restless leg syndrome, says von Drygalski ...
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 ...
An analysis of data from more than 8,000 adults in the U.S. revealed that 14% had low iron blood levels, a condition known as absolute iron deficiency, while 15% had the right iron levels but ...
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]
Mineral deficiency is a lack of the dietary minerals, the micronutrients that are needed for an organism's proper health. [1] The cause may be a poor diet , impaired uptake of the minerals that are consumed, or a dysfunction in the organism's use of the mineral after it is absorbed.
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.
Absorption of dietary iron in iron salt form (as in most supplements) varies somewhat according to the body's need for iron, and is usually between 10% and 20% of iron intake. Absorption of iron from animal products, and some plant products, is in the form of heme iron, and is more efficient, allowing absorption of from 15% to 35% of intake.
Iron is also stored as a pigment called hemosiderin, which is an ill-defined deposit of protein and iron, created by macrophages where excess iron is present, either locally or systemically, e.g., among people with iron overload due to frequent blood cell destruction and the necessary transfusions their condition calls for. If systemic iron ...
