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]
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.
Iron metabolism disorders may involve a number of genes including HFE and TFR2. [1]Hepcidin is the master regulator of iron metabolism and, therefore, most genetic forms of iron overload can be thought of as relative hepcidin deficiency in one way or another.
Iron-deficiency anemia is the most common type of anemia overall and it has many causes. RBCs often appear hypochromic (paler than usual) and microcytic (smaller than usual) when viewed with a microscope. Iron-deficiency anemia is due to insufficient dietary intake or absorption of iron to meet the body's needs. Infants, toddlers, and pregnant ...
Plummer–Vinson syndrome (also known as Paterson–Kelly syndrome [1] or Paterson–Brown-Kelly syndrome in the UK [2]) is a rare disease characterized by dysphagia (difficulty swallowing), iron-deficiency anemia, glossitis (inflammation of the tongue), cheilosis (cracking at the corners of the mouth), and esophageal webs (thin membranes in the esophagus that can cause obstruction). [1]
Attacks are most common in young adult women and are rare before puberty or after menopause. [8] Severe acute attacks may require hospitalization. Patients usually experience symptoms in attacks that last from several hours to a few days. Between attacks, patients are asymptomatic. [citation needed]
Patients are also sometimes treated pharmacologically. To both induce menses and improve bone density, doctors may prescribe cyclic estrogen or progesterone as is used to treat post-menopausal women. [5] Patients may also be put on oral contraceptives to stimulate regular periods. [5]
