Microcytic anemia is characterised by small red bloodcells. The normal mean corpuscular volume (abbreviated to MCV on full blood count results) is 80-100 fl, with smaller cells described as microcytic and larger cells as macrocytic. Anemia (American English) or anaemia (Commonwealth English), which literally means without blood, is a lack of red blood cells and/or hemoglobin. ... Red blood cells (erythrocytes) are present in the blood and help carry oxygen to the rest of the cells in the body Blood is a circulating tissue composed of fluid plasma and cells (red blood cells, white blood cells, platelets). ... A cell is a single unit or compartment, enclosed by a border or wall. ... A full blood count (FBC) or complete blood count (CBC) is a test requested by a doctor or other medical professional that gives information about the cells in a patients blood. ...
Microcytic anemia is caused by a lack of hemoglobin, meaning that cell division in the bone marrow continues for longer than usual, resulting in smaller cells. The thalassemias are one relatively common cause of a hemoglobin shortage. 3-dimensional structure of hemoglobin Hemoglobin or haemoglobin is the iron-containing oxygen-transport metalloprotein in the red cells of the blood in mammals and other animals. ... Bone marrow is the tissue comprising the center of large bones. ... Thalassemia (American English) (or Thalassaemia in British English) is an inherited disease of the red blood cells, classified as a hemoglobinopathy. ...
Anemia is a blood disorder characterized by abnormally low levels of healthy RBCs or reduced levels of hemoglobin (Hgb), the iron-bearing protein in RBCs that delivers oxygen to tissues throughout the body.
Iron deficiency anemia is the most common type of anemia throughout the world, although it occurs to a lesser extent in the United States because of the higher consumption of iron-rich red meat and the practice of food fortification (addition of iron to foods by manufacturers).
Iron deficiency anemia can develop as a result of depleted iron stores from chronic blood loss, increased demands for iron as seen in periods of growth (e.g., in infancy and adolescence), or malabsorption of iron even when foods or supplements are supplying adequate amounts.
