[3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [1]
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 ...

[11] [12] The absorption of heme iron is 2–3 times faster than non-heme iron. [13] After absorption, the iron from preparation becomes part of the iron pool in the body. Upon stimulation, the reduction of iron storage Fe3+ in the enterocyte to Fe2+ ferroportin allows the passage of iron through the cell membrane for export.

Specialty. Endocrinology.

[2] It is important to assess this condition because individuals with latent iron deficiency may develop iron-deficiency anemia.
