Before iron deficiency anemia sets in, “the body will do everything it can to retain the right number of red blood cells. So, it will deplete the storage iron before it depletes the red blood ...
[157] [158] In the United Kingdom, a National Diet and Nutrition Survey (NDNS) was conducted in adults aged between 19 and 64 years in 2000–2001 [159] and in elderly individuals (≥ 65 years) in 1994–95. [160] Six percent of men (n = 632) and 10% of women (n = 667) had low serum vitamin B 12 concentrations, defined as < 150 pmol/L.
Main symptoms that may appear in anemia [20] The hand of a person with severe anemia (on the left, with ring) compared to one without (on the right). A person with anemia may not have any symptoms, depending on the underlying cause, and no symptoms may be noticed, as the anemia is initially mild, and then the symptoms become worse as the anemia worsens.

Mild and moderate anemia have symptoms that develop slowly over time.[5] If patients believe that they are at risk for or experience symptoms of anemia, they should contact their doctor. [8]
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 ...
Stage 3 – Anemia (reduced hemoglobin levels) is present but red blood cell appearance remains normal. [4] Stage 4 – Changes in the appearance of red blood cells are the hallmark of this stage; first microcytosis and then hypochromia develop. [4] Stage 5 – Iron deficiency begins to affect tissues, manifesting as symptoms and signs. [4]
