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]
Anemia (also spelled anaemia in British English) is a blood disorder in which the blood has a reduced ability to carry oxygen.This can be due to a lower than normal number of red blood cells, a reduction in the amount of hemoglobin available for oxygen transport, or abnormalities in hemoglobin that impair its function.
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.
Aplastic anemia [2] (AA) [3] is a severe hematologic condition in which the body fails to make blood cells in sufficient numbers. Blood cells are produced in the bone marrow by stem cells that reside there. [4] Aplastic anemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets. [5] [6]
Sideroblastic anemia, or sideroachrestic anemia, is a form of anemia in which the bone marrow produces ringed sideroblasts rather than healthy red blood cells (erythrocytes). [1] In sideroblastic anemia, the body has iron available but cannot incorporate it into hemoglobin , which red blood cells need in order to transport oxygen efficiently.
Cooley noted similarities in symptoms of children in his care having Greek or Italian ancestry; he named it "erythroblastic anemia," but it became popularly known as Cooley's anemia (now termed beta thalassemia major). [117] The term "thalassemia" was coined by George Whipple in 1932. The word "thalassemia" comes from the Greek word thalassa ...
Congenital dyserythropoietic anemia type II (CDA II), or hereditary erythroblastic multinuclearity with positive acidified serum lysis test (HEMPAS) [1] is a rare genetic anemia in humans characterized by hereditary erythroblastic multinuclearity with positive acidified serum lysis test.
