what is anemia?!
Question:
tellme anemic conditions breifly
Answers:
Anemia or anaemia (see spelling differences), which literally means "without blood," is a deficiency of red blood cells and/or hemoglobin. This results in a reduced ability of blood to transfer oxygen to the tissues, and this causes hypoxia; since all human cells depend on oxygen for survival, varying degrees of anemia can have a wide range of clinical consequences. Hemoglobin (the oxygen-carrying protein in the red blood cells) has to be present to ensure adequate oxygenation of all body tissues and organs.
The three main classes of anemia include excessive blood loss (acutely such as a hemorrhage or chronically through low-volume loss), excessive red blood cell destruction (hemolysis) or deficient red blood cell production. In menstruating women, dietary iron deficiency is a common cause of deficient red blood cell production.
Anemia is the most common disorder of the blood. There are several kinds of anemia, produced by a variety of underlying causes. Anemia can be classified in a variety of ways, based on the morphology of RBCs, underlying etiologic mechanisms, discernible clinical spectra, to mention a few.
Different clinicians approach anemia in different ways; two major approaches of classifying anemias include the "kinetic" approach which involves evaluating production, destruction and loss, and the "morphologic" approach which groups anemia by red blood cell size. (Schier) The morphologic approach uses a quickly available and cheap lab test as its starting point (the MCV--see below). On the other hand, focusing early on the question of production (e.g., via the reticulocyte count) may allow the clinician to more rapidly expose cases where multiple causes of anemia may coexist. Regardless of one's philosophy about the classification of anemia, however, methodical clinical evaluation should yield equally good results.

If you have anemia, people may say you have tired blood. That's because anemia — a condition in which there aren't enough healthy red blood cells to carry adequate oxygen to your tissues — can make you feel tired.
Anemia is a common blood disorder, affecting an estimated 3.4 million Americans. Women and people with chronic diseases are at increased risk of the condition.

Anemia is g Greek word for “bloodlessness”. A blood condition involving an abnormal reduction in the number of red blood cells or in their hemoglobin content. These cells are the means by which oxygen is carried to the various parts of the body. People who are anemic develop symptoms caused by the inadequate delivery of oxygen to their body tissues. There are three primary causes of anemia: (1) reduced production of red blood cells, which may result from deficiency in nutrients or hormones, or from disease or other conditions; (2) excessive destruction of red blood cells, often a hereditary problem; and (3) excessive blood loss.
The most common type of anemia is iron-deficiency anemia, which occurs when the body's need for iron increases, as during certain periods of childhood and in pregnancy, or when there is insufficient iron in the diet. Pernicious anemia, a chronic ailment that mostly affects people over 40, is a result of vitamin B 12 deficiency, often caused by decreased B12 absorption rather than a deficient diet. The most common symptoms of anemia are pallor, shortness of breath, low vitality, dizziness, and digestive disorders. Sickle-cell anemia is the result of a hereditary defect in the synthesis of hemoglobin.

My wife is anemic,she's always tired and cold.She went to the doctor and he put her on some high iron pills.
Anemia is the condition of having less than the normal number of red blood cells or less than the normal quantity of hemoglobin in the blood. The oxygen-carrying capacity of the blood is, therefore, decreased. Persons with anemia may feel tired and fatigue easily, appear pale, develop palpitations and become unusually short of breath. Children with chronic anemia are prone to infections and learning problems.

Anemia is defined as reduction in the aomount of hemoglobin in the red blood cells.
