Anemia or anaemia or anaemic, from the Greek meaning "without blood", refers to a deficiency of red blood cells (RBCs) and/or hemoglobin. This results in a reduced ability of blood to transfer oxygen to the tissues, causing 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 blood cell destruction (hemolysis) or deficient red blood cell production (ineffective hematopoiesis). 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, and 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. The morphologic approach uses a quickly available and cheap lab test as its starting point (the MCV). On the other hand, focusing early on the question of production (e.g., via the reticulocyte count) may allow the clinician more rapidly to expose cases where multiple causes of anemia coexist. Regardless of one's philosophy about the classification of anemia, however, any methodical clinical evaluation should yield equally good results.

Anaemia is a deficiency of red blood cells, which can lead to a lack of oxygen-carrying ability, causing unusual tiredness and other symptoms. Anaemic is lack of blood.

anaemic is the situation in which the body has less blood. it cn lead to many serious conditions. Anaemic conditions are most common in females

It literally comes from Greek meaning 'without blood'. In fact it is where the blood is low in red corpuscles - probably due to shortage of iron in the diet.

lacking iron /haemoglobin in the red blood cells. it is usually treated by increasing iron intake in the diet and by taking iron supplements. There are different types of anemia however and people who have sickle cell anaemia are treated very differently and those with pernicious anaemia lack vitamin B12 and need monthly injections as their treatment.

It is low blood levels, not necessarily low iron, although that can be a contributory factor. I suffer from it and have to inject myself every week with an enzme to make my bone marrow produce more blood.

Suffering from anaemia: sickly, spiritless, washed-out, lacking in body.
