ANEMIA / LOW HAEMOGLOBIN

It is a condition in the body when supply of iron to bone marrow falls short of that required for the production of red blood cells. It is the commonest cause of Anemia throughout the world.

"There are cases...in which [the blood's] amount of globules falls much below the physiological mean, and diminishing more and more, reaches a proportion so low that we can scarcely comprehend how, with so few globules in the blood, life can still be maintained. This diminution, in different degrees, of the globular element of the blood is the fundamental character of Anemia, a condition which is the opposite of plethora." Gabriel Andral, 1843
