According to MedicineNet.com, anaemia is a decrease in
number of red blood cells (RBCs) or less than the normal quantity of
haemoglobin in the blood. Anaemia may also be diagnosed where there is
decreased oxygen-binding ability of each haemoglobin molecule due to deformity
or lack in numerical development as in
number of red blood cells (RBCs) or less than the normal quantity of
haemoglobin in the blood. Anaemia may also be diagnosed where there is
decreased oxygen-binding ability of each haemoglobin molecule due to deformity
or lack in numerical development as in
some other types of haemoglobin
deficiency. Because haemoglobin (found inside RBCs) normally carries oxygen
from the lungs to the capillaries, anaemia leads to hypoxia (lack of oxygen) in
organs. Since all human cells depend on oxygen for survival, varying degrees of
anaemia can have a wide range of clinical consequences.
Anaemia is the most common disorder of the blood. The several kinds of anaemia
are produced by a variety of underlying causes. It 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. The three main
classes include excessive blood loss (acutely such as a haemorrhage or
chronically through low-volume loss), excessive blood cell destruction (haemolysis)
or deficient red blood cell production (ineffective haematopoiesis).
